JH Traction Battery Operating Instructions

These operating instructions apply only to Jungheinrich battery models. If using another brand, refer to the manufacturer's operating instructions.

A Correct use and

The „Guidelines for the Correct Use and Application of Industrial Trucks“ (VDMA) are included in the scope of delivery for this truck. The guidelines are part of these operating instructions and must always be heeded. National regulations are fully applicable.

The fork-lift truck described in these operating instructions is a truck that is suitable for lifting and transporting loads.

It must be used, operated and maintained according to the information in these operating instructions. Any other uses are outside the design envelope and can lead to injury to persons or damage to equipment and property. Above all, overloading caused by excessively heavy or unbalanced loads must be avoided. The max. admissible load to be picked up is indicated on the identification plate or load diagram label shown on the truck. The operator must ensure that damaged and/or poorly readable load diagrams are renewed. The fork-lift truck must not be operated in spaces subject to fire or explosion hazards, or in spaces where corrosive or very dusty atmospheres prevail.

Duties of the user: A „user“ within the meaning of these operating instructions is defined as any natural or legal person who either uses the fork-lift truck himself, or on whose behalf it is used. In special cases (e.g. leasing or renting), the user is considered the person, who, in accordance with existing contractual agreements between the owner and the user of the fork-lift truck, is charged with the observance of the operating duties.

The user must ensure that the truck is not abused and only used within its design limits and that all danger to life and limb of the operator, or third parties, is avoided. In addition to this, it must be ensured that the relevant accident prevention regulations and other safety-related provisions, as well as the operating, servicing and maintenance guidelines, are observed. The user must also ensure that all persons operating the truck have read and understood these operating instructions.

If these operating instructions are not observed the warranty becomes void. The same applies if improper works are carried out at the device by the customer and/or third parties without permission of our Customer Service.

Mounting of attachments: The mounting or installation of any attachments which will interfere with, or supplement, the functions of the truck is permitted only after written approval by the manufacturer has been obtained. If necessary, the approval of local authorities has to be obtained.

Any approval obtained from local authorities does not, however, make the approval by the manufacturer unnecessary.

Trailing and slipping loads: The truck may only be used for trailing or slipping loads for which the truck has been approved.

B Description of tr

1 D e s i g n a n d a p p

EFG 422-430 is an electric rider-controlled fork lift truck in four-wheel construction with front drive which picks up, transports, and lifts its load outside the wheelbase. It is a cantilevered counterbalance truck which can – due to its load lifting device being located in front of the lift truck – unload lorries and deliver the load on ramps or in racks unimpededly. It can be used to stack and transport DIN 15142 pallets, DIN 15144 lattice box pallet, and other palletised loads.

Truck types and maximum carrying capacity:

2.1 Truck

Steering (8): When a load is applied to the driver seat the steering is switched to Standby. The steering unit runs at a preset idle speed. Depending on the steering request the steering pump is increased and the travel speed is reduced depending on the steering arc (“CurveControl”). The steering angle is indicated in the display.

Driver seat (2): The driver seat is a comfort seat and the steering column is adjustable. There are storage places for documents or personal belongings of the driver. The MULTI-PILOT combines all hydraulic functions and the travel direction switch in one single lever. The overhead guard (1) is prepared for a cabin installation and thus can be easily retrofitted.

Electric/electronic system: Sophisticated three-phase AC technology enables data transfers with few cables only (CAN bus). Thus we achieve decreased susceptibility to faults caused be broken cables as well as considerably faster fault isolation. The complex TC system (Total Control) is designed for simply, safe, and flexible usage. Depending on the load the driver can select from different operating programmes: from high-performance to energy-saving. Convenient and very fast fault analysis and programming can be performed via PC.

Drive and brake system: The front drive offers ideal traction to the drive wheels at all times.

The hydraulically actuated oil-bath multi-disk brake used a service brake is practically maintenance-free. The encapsulation in the transmission allows applications even in aggressive environments. In addition, the lift truck is generatively braked via the travel motor. Thus the energy consumption is minimised.

After approximately 15 sec standstill of the truck or 1 to 15 sec (adjustable) after the driver seat is relieved the spring-loaded brake engages.

When actuating the accelerator the spring-loaded brake is automatically disengaged.

Hydraulic system: All functions must be executed sensitively, proportionally, and simultaneously (only if this does not impair the safety). For higher efficiency a hydraulic unit and a steering booster motor function separately from each other. The micro pressure filter can be changed from the top (without spilling hydraulic oil).

Lifting mast (7): Our goal is optimising the view. The high-strength steel profiles are narrow, which is especially notable in the three-stage lifting mast with its good view to the fork arms. The same good results are achieved for the fork arm carriage.

The lifting mast as well as the fork arm carriage move on prelubricated and thus maintenance-free cocked support rollers.

Technical specification details in accordance with VDI 2198. Technical modifications and additions reserved.

-Turn the EMERGENCY DISCONNECT and key switch off.

- Secure the truck to prevent it from rolling away

- Place a spanner on the hex. bolt (6) and turn the drive to the required steering position.

6 Towing the truck

• Connect a tow-rod/towing rope at the trailer coupling of the recovery vehicle and at the truck to be towed.
• Disconnect the battery plug (observe item D3!).
• Disengage the parking brake.

There must be a person for steering the truck on the driver seat of the truck to be towed. Tow the truck at walking speed!

As the steering booster is not switched on, the truck can only be steered with increased effort.

For trucks with a multifunctional steering wheel (○) only authorised persons may only tow the truck out of the hazard area for slow shunting. The truck can only be moved using a recovery truck and a tow bar. The emergency steering must be applied as described in “Steering the Truck without its own Drive System”

Before commissioning or operating the truck, and before raising a load, the driver must ensure that there is nobody in the hazardous area and that the truck is safe to operate.

3.1 Checks and operations to be performed before starting daily work

Before starting the truck the driver must ensure it is safe to operate. Before starting work, check for example that

– the operating and parking brakes or the automatic brake (Emergency Stop) are working
-the fork tine retainer preventing the tines from moving is not defective
– the load handler does not show visible signs of damage (bent, cracks or heavy wear)
-the warning device is working

3.2 Trucks with reduced headroom X (○)

Failure to comply with the recommended body size may result in overload constitute a danger to the driver, possibly resulting in permanent damage caused by an unhealthy posture and excessive physical exertions on the part of the driver.

The owner must ensure that the truck operator does not exceed the maximum body size indicated.

The owner must also check that the drivers can sit normally, in an upright position without having to exert himself.

3.3 Adjusting the driver's seat

To achieve optimal seat cushioning, the driver's seat must be adapted to the driver's weight.

The driver's seat must be adapted to the driver's weight.

Adjusting the driver's weight:

- Pull the "driver's sea (92) in the direction of the arrow as far as the stop and then return it.

The previous weight setting is reset to the minimum value. The seat suspension can be set from 50 kg to 130kg

- Move the "driver's adjuster (92) again in the direction of the arrow until the corresponding weight marking on the "driver's seat" weight display (93) is reached. N return the "driver's seat" weight adjuster.

-Sit on the driver's seat.

The driver's seat must be securely locked in the desired position. The driver's seat setting must not be changed during travel.

The procedure for adjusting the driver's seat applies to standard models. For other models, follow the manufacturer's setting instructions. When adjusting the seat make sure that all controls are within easy reaching distance.

3.4 Safety restraint belt

Put on the safety restraint belt each time before starting the industrial truck. The belt protects against serious injury.

Protect the belt from contamination (e.g. cover it when the truck is idle) and clean it regularly. Frozen belt locks or pulleys must be thawed out and dried to prevent them from freezing up again.

The dry temperature of the warm air should not exceed +60 °C.

Do not alter the belt setting. This will increase the risk of malfunctioning.

- Always replace the safety restraint belt after an accident. - Only original spare parts must be used for retrofits or repairs.

Damaged or non-operational belts must only be replaced by contractual dealers or branches.

Procedure in unusual situations

If the truck is about to tip over, under no circumstances should you the restraint belt and try to jump out. Jumping increases the risk of injury.

Correct procedure:

- Lean your upper body over the steering wheel.

- Grip the steering wheel with both hands and brace feet.

- Lean your body against the opposite direction of fall

Restraint belt operating instructions

Before starting the truck carefully pull the belt out of the pulley, pull it tightly across your body and over your thigh, and engage it in the lock.

The belt must not be twisted when fastened.

When operating the truck (e.g. travelling, lifting, lowering, etc.), sit as far back as possible so that your back is against the backrest.

The automatic locking retractor allows sufficient freedom of movement on the seat.

Sitting at the front edge of the seat affords less protection, as the belt is too long.

The belt is only to be used to secure one person.

- After using the belt, push the red button and manually guide the tongue back to the retractor.

The automatic blocking system can be triggered if the seat belt tongue strikes the housing. This will prevent the belt from being extracted.

Deactivating the blocking system:

- Apply force to pull the belt 10mm – 15mm out of its housing. - Feed the belt back in to undo the automatic blocking system

The belt can now be extracted again.

Starting the industrial truck on steep slopes

The automatic blocking system locks the belt in the retractor when the truck is positioned on a steep slope. This prevents the belt from being pulled out of the retractor.

Carefully drive the truck off the slope and then put on the belt.

3.5 Safety Restraint System (○)

Never use the truck with a non-functional restraint system.

The restraint system must be checked by authorised specialist personnel after an accident.

Do not alter the restraint system.

When the driver's seat is occupied, maintain a 90 mm gap between the gate (96) and the seat to ensure safety.

96 90

Procedure in unusual situations

If the truck is in danger of tipping over, do not try to jump out. This will only increase the risk of injury.

Correct procedure

• Lean your upper body over the steering wheel.
  – Grip the steering wheel with both hands and brace feet.
• Tilt your body in the opposite direction of fall.

3.5.1 Safety restraint system (automatic) operating instructions (○)

Test the restraint system before starting the truck.

The stop knob (97) must not be engaged.

-Sit down on the seat -Turn the key switch "

After releasing the parking brake the two safety gates (LH and RH) close and lock automatically.

4.1 Safety regulations for truck operation

Travel routes and work areas: Only use lanes and routes specifically designated for truck traffic. Unauthorised third parties must stay away from work areas. Loads must only be stored in places specially designated for this purpose.

Driving conduct: The driver must adapt the travel speed to local conditions. The truck must be driven at slow speed when negotiating bends or narrow passageways, when passing through swing doors and at blind spots. The driver must always observe an adequate braking distance between the forklift truck and the vehicle in front and must be in control of the truck at all times. Abrupt stopping (except in emergencies), rapid U turns and overtaking at dangerous or blind spots are not permitted. It is forbidden to lean out of or reach beyond the working and operating area.

Travel visibility: The driver must look in the direction of travel and must always have a clear view of the route ahead. When carrying loads which affect visibility, these must be stored at the rear of the truck. If this is not possible, a second person must walk in front of the truck as a lookout.

Negotiating slopes and inclines: Negotiating slopes or inclines is only permitted if such roads are clean and have a non-slip surface and providing such journeys are safely undertaken in accordance with the technical specifications for the truck in question. The truck must always be driven with the load unit facing uphill. The industrial truck must not be turned, operated at an angle or parked on inclines or slopes. Inclines must only be negotiated at slow speed, with the driver ready to brake at any moment.

Negotiating lifts and docks: Lifts and docks must only be used if they have sufficient capacity, are suitable for driving on and authorised for truck traffic by the owner. The driver must satisfy himself of the above before entering these areas. The truck must enter lifts with the load in front and must take up a position which does not allow it to come into contact with the walls of the lift shaft. People travelling in the lift with the forklift truck must only enter the lift after the truck has come to a halt and must exit the lift before the truck.

Type of loads to be carried: The operator must make sure that the load is in a satisfactory condition. Do not carry loads unless they are positioned safely and carefully. Use suitable precautions, e.g. a load guard, to prevent parts of the load from tipping or falling down.

Towing trailers or the truck itself being towed are only permitted occasionally, on secure, level routes, with a maximum deviation of +/- 1% and at a max. speed of 5 km/h. Do not permanently operate the truck with trailers.

When the truck is pulling there must be no load on the forks.

Do not exceed the maximum trailer load specified for the forklift truck for trailers with or without brakes. The specified trailer load only applies for the auxiliary coupling in the counterbalance of the forklift. If a different trailer coupling is used on the truck, the instructions of the coupling manufacturer must be observed..

After coupling and before starting the driver must ensure that the trailer coupling cannot become detached.

Trucks pulling a load must be operated in such a manner that the trailing vehicle is driven safely and can be stopped at all times.

4.2 Travel

Travelling in electromagnetic fields beyond the permitted limits can result in random truck motion.

Immediately apply the EMERGENCY DISCONNECT, brake with the service brake and apply the parking brake.

Determine the cause of the fault and if necessary inform the manufacturer's service department.

Safety functions

If the driver's seat is not occupied (safety belt ○) not closed) or if the driver's weight is set too high, travel is interrupted by the safety switch (see Section 3 "Setting the Driver's Weight"). Occupying the driver's seat and applying the accelerator pedal releases the spring-loaded brake.

The travel speed reduces as a function of the steering angle. However, the driver is still responsible for adapting the travel speed to the conditions of the travel route, the work area and the load.

Do not drive the truck unless the panels are closed and properly locked.

Travel routes must be free of obstacles.

Braking

The braking pattern depends largely on the ground conditions. The driver must take this into consideration when handling the truck. Brake with care to prevent the load from slipping.

If you are travelling with an attached load you must increase the braking distance.

- Take your foot off the accelerator pedal (6) (11/13) and if necessary gently apply the brake pedal (7/12) (see also Section 4.4).

4.3 Steering

Very minimal steering effort is required for the electric steering, therefore turn the steering wheel sensitively.

Negotiating right hand bends

- Turn the steering wheel clockwise to match the desired steering radius.

Negotiating left hand bends

- Turn the steering wheel anti-clockwise to match the desired steering radius.

4.4 Braking

There are four ways of braking:

• Service brake
• Coasting brake
• Reversing brake
• Parking brake
• Spring-loaded brake

Service brake:

- Depress the brake pedal (7/12) until you feel the brake pressure.

The service brake acts on the drive wheels via the multi-plates.

Technical diagram showing car interior components with numbered labels pointing to different parts of the dashboard.

Coasting brake:

- Take your foot off the pedal (6) (11/13). The truck brakes regeneratively via the traction controller.

This operating method reduces energy consumption.

Reversing brake (twin pedal)

During travel, depress the accelerator pedal (11/13) for the opposite direction. The truck brakes regeneratively via the traction controller until it starts to travel in the opposite direction.

Parking brake:

- Apply the parking brake

The parking brake actuates a black and white valve, braking cannot be performed with any degree of sensitivity.

The parking brake acts mechanically on the drive wheels via the multi-plates.

The parking brake will keep the truck with the maximum permissible load, on a clean ground surface, on a 15 % incline.

Spring-loaded brake

The spring-loaded brake applies approx. 30 seconds (adjustable) after the truck comes to a halt, and approx. 1 to 5 seconds (adjustable) after the driver's seat has been vacated.

When you stop on the ramp the truck is held electrically until the spring-loaded brake applies.

When you set off, before the spring-loaded brake is released, a torque builds up on the drive motor to prevent the truck from rolling back.

4.5 Operating the lift mechanism and attachments (MULTI-PILOT)

The Multipilot must only be operated from the driver's seat. The driver must be instructed in how to handle the lift mechanism and the attachments.

Push the Multipilot in the desired direction, depending on the hydraulic function.

• Pull the auxiliary hydraulics control lever ZH2 (19) backwards or push it forward to control the attachment (e.g. fork positioner).
• You can use button (20) to toggle the ZH2 control lever (19) to auxiliary hydraulics ZH3.

The auxiliary hydraulics ZH3 can only be activated when the button (20) is pressed and the control lever is in the neutral position. To control the attachment, pull the SOLO-PILOT ZH2 lever (19) back or push it forward. The auxiliary hydraulics ZH3 are deactivated when the button (20) is released and the control lever has returned to the neutral position.

Moving the lever controls the lift speed of the hydraulic cylinder.

When the lever is released it automatically reverts to neutral and the lifting device remains in the position it has reached.

Always apply the control lever sensitively, never with a sudden jerk. Release the control lever as soon as the lifting device reaches the limit position.

Integrated Sideshift (○)

The fork carriage can be moved sideways using the integrated sideshift.

• Pull the auxiliary hydraulics control lever ZH1 (18) back = sideshift right.
• Push the auxiliary hydraulics control lever ZH1 (18) forward = sideshift left.

Integrated fork positioner (○)

The integrated fork positioner allows the distance between the forks to be set.

• Pull the auxiliary hydraulics control lever ZH2 (19) back = forks together.
• Push the auxiliary hydraulics control lever ZH2 (19) forward = forks apart.

The fork positioner can be synchronised to ensure the forks are even. The forks must be spread apart as far as the stop and then brought back together.

Other Attachments

Additional equipment can only be attached with written permission from the manufacturer, see chapter A “Attaching Accessories”. Always follow the manufacturer’s operating instructions when using other attachments.

The control levers of the attachments must be indicated by symbols to illustrate the function of the attachment.

Only use attachments that have CE approval. The reduced residual capacity must be re-calculated and indicated by a separate capacity plate.

4.7 Operating the lift mechanism and attachments (multifunction steering wheel)

4.10 Towing trailers

The truck can occasionally be used to tow a light trailer on a dry, level and well maintained surface.

The max. tow load is the capacity indicated on the capacity data plate (see decals diagram in chapter B).

The tow load consists of the weight of the trailer and the stated capacity.

If a load is transported on the forks, the tow load must be reduced by the same amount.

Important notes for safe towing

– A truck must not be continually operated with trailers.
- No supporting loads are permitted.
– The maximum speed is 5 km/h.
- Towing must only be performed on level, secure travel routes.
- Follow the instructions of the coupling manufacturer if using special trailer couplings.
- The owner must test trailer operation with the permissible tow load by means of a trial run under the applicable operating conditions in the field.

Attaching the trailer

- Push the tow pin (117 it 90 degrees.

- Pull the tow pin up of the trailer vehicle into the opening.

- Insert the tow pin, push it down, turn it 90 degrees and engage it.

If the fault cannot be rectified after carrying out the remedial procedure, notify the manufacturer's service department, as any further troubleshooting can only be performed by specially trained and qualified service personnel.

F Maintenance of

The checks and servicing operations contained in this chapter must be performed in accordance with the intervals as indicated in the servicing checklists.

Modifications of fork lift truck assemblies, especially of the safety installations, are not permitted. On no account must the operational speeds of the truck be changed.

Only original spare parts have been certified by our quality assurance service. To ensure safe and reliable operation of the fork lift truck, only spare parts of the manufacturer must be used. Used parts, oils and fuels must be disposed of in accordance with the applicable environmental protection regulations. For oil changes, the oil service of the manufacturer is available to you.

Upon completion of any checking and servicing activities, the operations contained in the section “Recommissioning” must be performed (refer to chapter F).

2 S a f e t y r e g u l a t

Servicing and maintenance personnel: The fork lift truck must only be serviced and maintained by trained personnel of the manufacturer. The service organization of the manufacturer has external technicians trained especially for these assignments. We thus recommend signing a maintenance contract with the relevant service location of the manufacturer.

Lifting and jacking up: When a fork lift truck is to be lifted, the lifting gear must only be secured to the points specially provided for this purpose. When the truck is to be jacked up, suitable measures must be taken to prevent the truck from slipping or tipping over (use of wedges, wooden blocks). Work underneath the raised load lifting device must only be carried out when the fork is immobilised and supported by a chain of adequate strength.

Jacking point see chapter B.

When work has to be performed under the raised fork or under the jacked up truck, suitable measures must be taken to prevent any dropping, tilting or slipping of the fork or truck. When lifting the truck, the instructions contained in chapter “Transportation and commissioning” have to be observed.

When performing work on the parking brake, the truck must be secured against moving.

Cleaning operations: No inflammable liquids must be used when cleaning the fork lift truck. Prior to commencing cleaning operations, all safety measures that are required to prevent sparking (e.g. by short-circuits) have to be taken. For battery-operated fork lift trucks, the battery plug must be removed. Only weak indraft, weak compressed air and non-conducting, antistatic brushes must be used for the cleaning of electric or electronic assemblies.

If the fork lift truck is to be cleaned using a water jet or a high-pressure cleaner, all electric and electronic components must be carefully covered beforehand because moisture can lead to incorrect functioning.

Cleaning by means of a steam jet is not permitted.

Upon completion of cleaning work, the operations detailed in the section "Recommissioning" must be performed.

Work on the electric system: Work on the electric system of the truck must only be performed by personnel specially trained for such operations. Before commencing any work on the electric system, all measures required to prevent electric shocks have to be taken. For battery-operated fork lift trucks, the truck must also be depowered by removing the battery plug.

Welding operations: To prevent any damage to electric or electronic components, these have to be removed from the fork lift truck before any welding operations are undertaken.

Settings: When repairing or replacing hydraulic, electric or electronic components or assemblies, all truck-specific settings have to be retained.

Wheels: The quality of wheels affects the stability and performance of the truck. When replacing wheels fitted at the factory, only use manufacturer's original spare parts. Otherwise the truck's rated performance cannot be ensured.

When replacing wheels, ensure that the truck does not slew (e.g. always replace wheels in pairs, i.e. left and right wheels at the same time).

Lift chains: The lift chains wear rapidly if not lubricated. The intervals in the service checklist apply to normal duty. If requirements are higher (dust, temperature), lubrication is required more often. The specified chain spray must be used as specified. The external application of grease does not provide sufficient lubrication.

The chain tensioners must be adjusted in such a manner that they can adapt themselves to the pulling direction of the chain. Pretensioning the tensioner head against the mounting is not allowed. A minimum distance of 20 mm must be kept.

Hydraulic hoses: The hoses must be renewed every six years. When replacing hydraulic components, also renew the hoses in this hydraulic system.

3 Servicing and inspection

Thorough and expert servicing is one of the most important preconditions for safe operation of the forklift truck. Failure to perform regular servicing can lead to truck failure and poses a potential hazard to personnel and equipment.

The application conditions of an industrial truck have a considerable impact on the wear of the service components.

We recommend that a Jungheinrich customer service adviser carries out an application analysis on site to work out specific service intervals to prevent damage due to wear.

The service intervals listed are based on single shift operation under normal operating conditions. They must be reduced accordingly if the truck is to be used in conditions where there is heavy dust, temperature fluctuations or multiple shifts.

The following maintenance check list gives the tasks and times at which they should be carried out. Maintenance intervals are defined as:

W = Every 50 service hours or at least weekly

A = E v e r y 5 0 0 s e r v i c e h o u

B = Every 1000 service hours, or at least six months

C = Every 2000 service hours, or at least annually

W service intervals are to be performed by the customer.

In the run-in period - after approx. 100 service hours - or after repair work, the owner must check the wheel nuts/bolts and re-tighten if necessary.

• Check the horn for proper functioning.
• Check the master switch for correct functioning.
• Check the brake for correct functioning.
• Lubricate truck according to lubrication schedule.

7 D e c o m m i s s i o n i n

If the fork lift truck is to be decommissioned for more than two months, it must be parked in a frost-free and dry location and all measures to be taken before, during and following decommissioning must be performed as detailed below.

During decommissioning, the fork lift truck must be jacked up, ensuring that the wheels are clear of the ground. Only this measure will ensure that wheels and wheel bearings do not suffer damage.

If the fork lift truck is to be decommissioned for more than 6 months, additional measures must be discussed with the Service Department of the manufacturer.

7.1 Operations to be performed prior to decommissioning

• Thoroughly clean the fork lift truck.
• Check the brakes for correct function.
• Check the hydraulic oil level and top up if required (refer to chapter F).

• Grease the fork lift truck as detailed in the lubrication chart (refer to chapter F).
  – Recharge the battery (refer to chapter D).
• Disconnect and clean the battery. Apply pole grease to the battery poles.

In addition to this, all instructions given by the battery supplier must be observed.

- Spray all exposed electrical contacts with a suitable contact spray.

7.2 Measures to be taken during decommissioning

Every 2 months:

– Recharge the battery (refer to chapter D).

⚠️ Battery-operated fork lift trucks: Regular recharging of the battery is very important; otherwise, exhaustive depletion of the battery caused by self-discharging would occur. Owing to sulfatisation, this will result in the destruction of the battery.

7.3 Recommissioning the truck

• Thoroughly clean the fork lift truck.
• Lubricate the fork lift truck according to the lubrication chart (refer to chapter F).
• Clean the battery. Grease the pole screws using pole grease and reconnect the battery.
  – Recharge the battery (refer to chapter D).
• Check if the gear oil contains condensed water and change if required.
• Check if the hydraulic oil contains condensed water and change if required.
• Start up the fork lift truck (refer to chapter E).

Battery-operated fork lift trucks:

If switching troubles are experienced in the electric system, spray the exposed contacts with contact spray and remove any oxide layer on the contacts of the operating controls by repeated operation.

Perform several brake tests immediately after recommissioning the truck.

8 S a f e t y t e s t s t c

Perform a safety check in accordance with national regulations. Jungheinrich recommends the truck be checked to FEM guideline 4.004. Jungheinrich has a safety department with trained personnel, able to carry out inspections.

The truck must be inspected at least annually or after any unusual event by a qualified inspector (be sure to comply with national regulations). The inspector shall assess the condition of the truck from purely a safety viewpoint, without regard to operational or economic circumstances. The inspector shall be sufficiently instructed and experienced to be able to assess the condition of the truck and the effectiveness of the safety mechanisms based on the technical regulations and principles governing the inspection of forklift trucks.

A thorough test of the truck must be undertaken with regard to its technical condition from a safety aspect. The truck must also be examined for damage caused by possible improper use. A test report shall be provided. The test results must be kept for at least the next 2 inspections.

The owner is responsible for ensuring that faults are immediately rectified.

A test plate is attached to the truck as proof that it has passed the safety inspection. This plate indicates the due date for the next inspection.

9 F i n a l d e - c o m m i

•Dangerous electrical voltage!
- Caution! Metal parts of the battery are always live. Do not place tools or other metal objects on the battery!

Ignoring the operation instructions, repair with non-original parts or using additives for the electrolyte will render the warranty void.

For batteries in classes ☒ I and ☒ II the instructions for maintaining the appropriate protection class during operation must be complied with (see relevant certificate).

1. Commissioning filled and charged batteries. For commissioning of unfilled batteries see separate instructions!

The battery should be inspected to ensure it is in perfect physical condition.

The charger cables must be connected to ensure a good contact, taking care that the polarity is correct. Otherwise battery, vehicle or charger could be damaged.

The specified torque loading for the polscrews of the charger cables and connectors are:

	steel
M 10 23	± 1 Nm

The level of the electrolyte must be checked. If it is below the antisurge baffle or the top of the separator it must first be topped up to this height with purified water.

The battery is then charged as in item 2.2.

The electrolyte should be topped up to the specified level with purified water.

2. Operation

DIN EN 50272-3 «Traction batteries for industrial trucks» is the standard which applies to the operation traction batteries in industrial trucks.

2.1 Discharging

Be sure that all breather holes are not sealed or covered.

Electrical connections (e.g. plugs) must only be made or broken in the open circuit condition.

To achieve the optimum life for the battery, operating discharges of more than 80% of the rated capacity should be avoided (deep discharge).

This corresponds to an electrolyte specific gravity of 1.13 kg/l at the end of the discharge. Discharged batteries must be recharged immediately and must not be left discharged. This also applies to partially discharged batteries.

2.2 Charging

Only direct current must be used for charging. All charging procedures in accordance with DIN 41773 and DIN 41774 are permitted. Only connect the battery assigned to a charger, suitable for the size of battery, in order to avoid overloading of the electric cables and contacts, unacceptable gassing and the escape of electrolyte from the cells.

In the gassing stage the current limits given in DIN EN 50272-3 must not be exceeded. If the charger was not purchased together with the battery it is best to have its suitability checked by the manufacturers service department. When charging, proper provision must be made for venting of the charging gases.

Battery container lids and the covers of battery compartments must be opened or removed. The vent plugs should stay on the cells and remain closed.

With the charger switched off connect up the battery, ensuring that the polarity is correct. (positive to positive, negative to negative). Now switch on the charger. When charging the temperature of the electrolyte rises by about 10^ C, so charging should only begin if the electrolyte temperature is below 45^ C. The electrolyte temperature of batteries should be at least +10^ C before charging otherwise a full charge will not be achieved.

A charge is finished when the specific gravity of the electrolyte and the battery voltage have remained constant for two hours. Special instructions for the operation of batteries in hazardous areas. This concerns batteries which are used in accordance with EN 50014, DIN VDE 0170/0171 Ex (in areas with a firedamp hazard) or Ex II (in potentially explosive areas). During charging and subsequent gassing the container lids must be removed or opened so that the explosive mixture of gases loses its flammability due to adequate ventilation. The containers for batteries with plate protection packs must not be closed until at least half an hour after charging has past.

2.3 Equalising charge

Equalising charges are used to safeguard the life of the battery and to maintain its capacity. They are necessary after deep discharges, repeated incomplete recharges and charges to an IU characteristic curve. Equalising charges are carried out following normal charging. The charging current must not exceed 5 A/100 Ah of rated capacity (end of charge - see point 2.2).

Watch the temperature!

2.4 Temperature

An electrolyte temperature of 30^ C is specified as the rated temperature. Higher temperatures shorten the life of the battery, lower temperatures reduce the capacity available. 55^ C is the upper temperature limit and is not acceptable as an operating temperature.

2.5 Electrolyte

The rated specific gravity (S. G.) of the electrolyte is related to a temperature of 30^ C and the nominal electrolyte level in the cell in fully charged condition. Higher temperatures reduce the specified gravity of the electrolyte, lower temperatures increase it. The temperature correction factor is -0.0007 kg/l per ^ C, e.g. an electrolyte specific gravity of 1.28 kg/l at 45^ C corresponds to an S.G. of 1.29 kg/l at 30^ C.

The electrolyte must conform to the purity regulations in DIN 43530 part 2.

3. Maintenance

3.1 Daily

Charge the battery after every discharge. Towards the end of charge the electrolyte level should be checked and if necessary topped up to the specified level with purified water. The electrolyte level must not fall below the anti-surge baffle or the top of the separator or the electrolyte „min“ level mark.

3.2 Weekly

Visual inspection after recharging for signs of dirt and mechanical damage. If the battery is charged regularly with a IU characteristic curve an equalising charge must be carried out (see point 2.3).

3.3 Monthly

At the end of the charge the voltages of all cells or bloc batteries should be measured with the charger switched on, and recorded. After charging has ended the specific gravity and the temperature of the electrolyte in all cells should be measured and recorded.

If significant changes from earlier measurements or differences between the cells or bloc batteries are found further testing and maintenance by the service department should be requested.

3.4 Annually

In accordance with DIN VDE 0117 at least once per year, the insulation resistance of the truck and the battery must be checked by an electrical specialist.

The tests on the insulation resistance of the battery must be conducted in accordance with DIN EN 60254-1.

The insulation resistance of the battery thus determined must not be below a value of 50 per Volt of nominal voltage, in compliance with DIN EN 50272-3.

For batteries up to 20 V nominal voltage the minimum value is 1000 Ω.

4. Care of the battery

The battery should always be kept clean and dry to prevent tracking currents. Cleaning must be done in accordance with the ZVEI code of practice «The Cleaning of Vehicle Traction batteries».

Any liquid in the battery tray must be extracted and disposed of in the prescribed manner. Damage to the insulation of the tray should be repaired after cleaning, to ensure that the insulation value complies DIN EN 50272-3 and to prevent tray corrosion. If it is necessary to remove cells it is best to call in our service department for this.

5. Storage

If batteries are taken out of service for a lengthy period they should be stored in the fully charged condition in a dry, frost-free room. To ensure the battery is always ready for use a choice of charging methods can be made:

1. a monthly equalising charge as in point 2.3
2. float charging at a charging voltage of 2.23 V x the number of cells. The storage time should be taken into account when considering the life of the battery.

6. Malfunctions

If malfunctions are found on the battery or the charger our service department should be called in without delay. The measurements taken in point 3.3 will facilitate fault finding and their elimination.

A service contract with us will make it easier to detect and correct faults in good time.

Back to the manufacturer!

Batteries with this sign must be recycled.

Batteries which are not returned for the recycling process must be disposed of as hazardous waste!

We reserve the right make technical modification.

1. Design

The Aquamatic/BFS battery water refilling systems are used for automatically adjusting the nominal electrolyte level. Venting holes are provided for letting off the gases which arise during charging. In addition to the optical level indicator, the plug systems also have a diagnostics hole for measuring the temperature and the electrolyte density. All battery cells of the design series EPzS; EPzB can be equipped with the Aquamatic/BFS filling systems. The water can be refilled by means of a central sealing coupler through the hose connections in the individual Aquamatic/BFS plugs.

2. Application

The Aquamatic/BFS battery water refilling system is used in traction batteries for forklift trucks. The water refilling system is provided with a central water connection for the water supply. Soft PVC hose is used for this connection and for the hose connections for the individual plugs. The hose ends are put onto the hose connection sleeves located on the T or < pieces.

3. Function

The quantity of water required in the refilling process is controlled by the valve located in the plug in combination with the float and the float rods. In the Aquamatic System the existing water pressure at the valve turns off the water supply and ensures that the valve closes securely. When the maximum filling level is reached in the BFS system, the float and the float rods through a lever system close the valve with five times the buoyant force and consequently interrupt the water supply reliably.

4. Filling (manual/automatic)

The batteries should be filled with battery water as soon as possible before the battery charging comes to an end; this ensures that the refilled water quantity is mixed with the electrolyte. In normal operation it is usually sufficient to fill once a week.

5. Connection pressure

The water refilling unit is to be operated in such a way that the water pressure in the water pipe is between 0.3 bars and 1.8 bars. The Aquamatic System has an operating pressure range of between 0.2 bars and 0.6 bars. The BFS system has an operating pressure range of 0.3 bars to 1.8 bars. Deviations from the pressure ranges impair the system's functional reliability. This wide pressure range permits three types of filling.

5.1 Falling water

The height of the tank is chosen to suit whichever water refilling system is used. For the Aquamatic System the installation height is 2 m to 6 m and for the BFS system the installation height is 3 m to 18 m over the battery surface.

5.2 Pressurised water

The pressure-reducing valve in the Aquamatic System is set from 0.2 bars to 0.6 bars and from 0.3 bars to 1.8 bars in the BFS system.

5.3 Water Refill Trolley (serviceMobil)

The submergible pump located in the ServiceMobil's tank generates the necessary filling pressure. No difference in height is permitted between the standing level of the ServiceMobil and the standing level of the battery.

6. Filling duration

The length of time needed to fill the batteries depends on the conditions under which the battery is used, the ambient temperatures and the type of filling and/or the filling pressure. The filling time is approx. 0.5 to 4 minutes. Where filling is manual, the water feed pipe must be separated from the battery after filling.

7. Water quality

Only refilling water which conforms in quality to DIN 43530 part 4 may be used to fill the batteries. The refilling unit (tank, pipelines, valves etc.) may not contain any kind of dirt which could impair the functional reliability of the Aquamatic/BFS plug. For safety reasons it is recommendable to insert a filter element (optional) with a max. passage opening of 100 to 300 m into the battery's main supply pipe.

8. Battery hose connections

Hose connections for the individual plugs are laid along the existing electric circuit. No changes may be made.

9. Operating temperature

The temperature limit for battery operation is set at 55^ C. Exceeding this temperature damages the batteries. The battery filling systems may be operated within a temperature range of >0^ C to a maximum of 55^ C.

CAUTION:

Batteries with automatic water refilling systems may only be operated in rooms with temperatures >0^ C (as there is otherwise a danger that the systems may freeze).

To be able to measure the acid density and temperature easily, the water refilling systems must have a diagnostics hole with a 6.5 mm-diameter (Aquamatic plugs) or a 7.5 mm-diameter (BFS plugs).

9.2 Float

Different floats are used depending on the cell design and type.

9.3 Cleaning

The plug systems may only be cleaned with water. No parts of the plugs may come in contact with soap or fabrics which contain solvents.

10. Accessories

10.1 Flow indicator

To monitor the filling process, a flow indicator can be inserted into the water feed pipe on the battery side. During the filling process, the paddlewheel is turned by the flowing water. When the filling process ends, the wheel stops and this indicates the end of the filling process. (ident no.: 50219542).

10.2 Plug lifter

Only the appertaining special-purpose tool may be used to disassemble the plug systems (plug lifter). The greatest of care must be employed when prising out the plug to prevent any damage to the plug systems.

10.2.1 Clamping ring tool

The clamping ring tool is used to push on a clamping ring to increase the contact pressure of the hose connection on the plugs' hose couplings and to loosen it again.

10.3 Filter element

For safety reasons a filter element (ident no.: 50307282) can be fitted into the battery's main supply pipe for supplying battery water. This filter element has a maximum passage cross-section of 100 to 300 m and is designed as a bag filter.

10.4 Sealing coupler

The water is supplied to the water refilling systems (Aquamatic/BFS) through a central supply pipe. This is connected to the water supply system at the battery charging station by means of a sealing coupler system. On the battery side a closing nipple (ident no.: 50219538) is mounted and the customer must place a sealing coupler construction on the water supply side (obtainable under ident. no.: 50219537).

11. Functional data

PS - self-sealing pressure: Aquamatic > 1.2 bars

BFS system none

D - rate of flow in the opened valve when the pressure is 0.1 bars: 350 ml/min

D1 - maximum permissible leakage rate in the closed valve when the pressure is at 0.1 bars: 2 ml/min

T - p e r m i s s i b l e t e m p e r a t u r e

Pa - operating pressure range: 0.2 to 0.6 bars in the Aquamatic system and operating pressure range: 0.3 to 1.8 bars in the BFS system.
