• Provide for safe storage of the tools. The tools that are not in current need should be stored at a dry unapproachable or an elevated place.
• Watch out for the cable. Do not pull the cable. To unplug, always grasp at the plug. Keep the cable at a safe distance from sources of heat, oil and sharp edges.
• Provide against unintentional switching. Always make sure that the tool switch is in OFF position before plugging in.

• When working outdoors, use special extension cables. To work outdoors, special extension cables are needed, mark in the appropriate way.

• Always remain concentrated. Mind what you are doing. Use common sense. Do not use electrical tools when feeling tired.

• Watch out for damaged parts. Check out the unit before use. Are some parts damaged? If the damage is slight, reconsider whether the unit is able of perfect and safe operation.
• Prevent any electrical shock. Avoid any contact of your body with grounded articles, e.g. water piping, heating radiators, stoves and fridges.
• Use approved parts only. For maintenance and repairs, use genuine spare parts only. The spare parts may be obtained from an authorised servicing centre.
• Warning! Use of accessories and additional parts other than those recommended in the operating manual may present a threat for persons and things.

Initial Operation Safety Instructions

• Before starting set-up or maintenance of the unit, disconnect it from the source.
  Connect the charger until the power supply, if all settings and the terminals are properly connected.
• Having removed the packing, make sure that the condition of the unit and any of its component is perfect.
• Unwind the power cable completely and put it so the pole terminals cannot get in touch with each other.
• If necessary, use an extension cable to extend the power cable; it must be of the same cross section as the power cable. Never use cable of smaller cross section.
• Keep the clamps, terminals and upper surface of the battery clean, if necessary, use the wire brush to clean the battery terminals. In this way, a good electrical contact will be provided and better charging efficiency secured.

- Never mix connections poling! ((-) black; (+) red)

- The charging voltage should be same as that shown on the battery i; the value is equal to the number of cells of a storage battery multiplied by two (3 cells = 6 V; 6 cells = 12 V; 12 cells = 24 V).

- Before charging, put the unit on a stable base and make sure that noting will prevent air flow through the respective holes. A good cooling system must be guaranteed.

- Do not charge more batteries at a time.

- The battery closure should be removed after cleaning the terminals not to have dust and dirt falling in the tubs.

- Provide for the electrolyte covering the plates up to the height of 4-5 mm at least, If necessary, add distilled water that may be obtained at shops for this purpose.

- In the course of charging, explosive gases develop abstain from smoking and naked fire or sparks.

- The batteries should be charged in well ventilated spaces. The charger is prohibited for use inside a vehicle or closed car bonnet.

- Never charge standard and maintenance-free batteries jointly.

- Never recharge disposable batteries.

- Leave sufficient ventilation space behind the unit.

Screw on the handle according to (Fig. 4).

Put the axle through the charger (Fig. 1/2). Fit the supplied safety rings on. Mount the wheels (Fig. 1/1) on the axle and secure them with safety rings (Fig. 5).

Put the wheels covers (Fig. 1/4) on.

Operation

Unplug before any adjustment and set up.

Charging (Fig .3)

• Connect the charger to the battery to be recharged
• Always connect the black cable first, to the negative pole. Connect the red pole cable to the positive pole.

The battery should be completely disconnected from the vehicle before getting down to charging.

• Always set the charger at the lowest charging degree (min/1).
• Now, plug in and control the charging degrees upwards until charging current equal to ca 10% of the battery capacity is displayed.
• Charging degrees may be increased by falling charging current.
• Do not disconnect the battery from terminals later than 3-5 hours after charging is finished.
• Notice. The charging current indicator will not come back to zero after charging is finished.

Charging Time

• The charging time always depends on the battery status (nearly charged, half-charged or completely discharged)
• To recover a battery that is normally in use 2 – 4 hrs are sufficient, while for full recharging 8-10 hrs are needed.
• Charging time should not be exceeded (10 hrs max.).

High-rate charging

4-6 levels allow high-rate charging that must in any case be limited by a timer.

• Connect the battery (see the "Handling" chapter).
• Set the charging level optionally to 4-6 and read the charging current on the ammeter.
• Set the timer to the required charging time (max. 60 minutes).

Start-up Assistance

• CAUTION! At the startup process can overvoltages arise, the on-board electronics could damage their vehicle. Please discuss with your automotive specialist.
• Connect the batteries as shown in part "Charging" and leave it connected to the vehicle!
• On principle, two persons should always start up a vehicle with chargers.
• The charger on max. Performance are: Switching stage 2 (Fig. 3, 7) and "boost" (Fig. 3, 8).
• The first person shall push the Start button on the charger (Fig.3, 9). The other one shall immediately start the ignition, max. 9-10 sec.
• As the vehicle starts up, stop starting immediately
• If the attempt to start fails, wait about 5 minutes for the charger to get cooled and only then begin another attempt to start.

Tip: If you change the battery for 10-15 minutes to subpoena requires much less battery power startup.

Warning: The fuses may burn through and the vehicle damaged if the starting time is more than 10 s.

Note: The terminals may not touch.

⚠️ Notice: The charger is equipped with overload protection.

IMPORTANT NOTICE!: Replacement fuses, the resistance values (Fig. 3,5) of which are different from the plate values, may cause material and personal damage. The fuses replacement should not be done unless the mains cable is unplugged

Operator Safety Instructions

- Any safety and protection devices must be fitted in place before switching the unit on.

• It is forbidden to attempt starting vehicles, the batteries of which are discharged or damaged as that would result in damaging the unit.
• Any attempts to start in position “charging” instead of “starting” could damage the ammeter and start the overload protection.
• Before pressing the main switch, make sure that the unit is connected correctly.
• Warning! If in doubt, consult a specialist in an authorized servicing centre.
• Do not use the unit until you have read the manual carefully.
• Observe all the safety regulation in this manual.
• Be responsible to the others.

Step-by-step Instruction

Charging

Troubles-Causes-Troubleshooting

Notice: Always check the overload protection first!

Overload circuit-breaker:

1. Connect the red clamp to the positive pole and the black one to the negative pole.
2. Remove the contact and check the fuses.
3. Set the charger at the lowest charging degree.
4. If the battery power input is too high, it is recommended to have the battery charging done by a skilled electrician and to keep the level of charge high by frequent charging or to get a more powerful charger. Have the battery checked by a specialist. Replace the battery.

Too heavy charging current at the beginning of charging

1. Watch out the charging current if it is high even after 15 - 20 minutes, it may mean that the charge would not hold Have the battery checked at a specialist's. Replace the battery.

Too weak charging current.

1. Try to adjust the charging current control higher.

Ammeter pointer touches the lowest position of the scale

1. Have the battery checked at a specialist. Replace the batteries
2. Ensure that the mains voltage is equal to the desired value

Ammeter does not indicate.

1. Clean the terminals and put the clamp on again.
2. Have it checked at a specialist's . Replace the battery.
   Check on the charger working ability on a perfect charged battery.

Overload Causes

1. Mixing up the poles when connecting the clamp to the battery
2. The battery is heavily or completely discharged.
