Assembly

For Your Safety

Warning! Switch off, remove the isolator key and the battery before adjusting, cleaning or if cable is cut, damaged or entangled. The blades continue to rotate for a few seconds after the machine is switched off. Caution - do not touch the rotating blade.

Battery Charging

Observe correct mains voltage: The voltage of the power source must agree with the voltage specified on the nameplate of the unit. Equipment marked with 230 V can also be connected to 220 V or 240 V.

Use only the charging unit supplied. Only this charging unit is matched to the lithium-ion battery used in the product.

The battery is equipped with temperature monitoring that allows charging only in the temperature range between 0°C and 45°C. In this manner, a high battery service life is achieved.

Note: The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery in the battery charger before using your power tool for the first time.

The lithium ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery.

The lithium-ion battery is protected against deep discharging when used in the product. When the battery is discharged, the product is switched off by a protective circuit and the product no longer operates.

Do not continue to press the On/Off switch after an automatic shut-off of the machine.

The battery can become damaged.

Charging Procedure

The charging procedure starts as soon as the mains plug of the battery charger is plugged into the socket outlet and the battery 8 is inserted into the charging compartment 16.

Due to the intelligent charging method, the charging condition of the battery is automatically detected and the battery is charged with the optimum charging current, depending on battery temperature and voltage.

This gives longer life to the battery and always leaves it fully charged when kept in the charger for storage.

Meaning of the Indication Elements

Control of the charging procedure is indicated via the charge control LEDs 18 and 19:

Rapid-charging Procedure

The rapid-charging procedure is indicated by flashing of the green charge control LED 19.

During the charging procedure, the three green LEDs light up one after the other and briefly go out. The battery is fully charged when the three green LEDs light up continuously. The three LEDs go out again approx. 5 minutes after the battery has been fully charged.

Note: The rapid-charging procedure is only possible when the battery temperature is within the allowable charging temperature range, see section "Technical Data".

Battery Charged

Continuous lighting of the green charge control LED 19 signals that the battery is fully charged.

Additionally, a signal tone sounds for approx. 2 seconds, which acoustically indicates that the battery is fully charged.

Afterwards, the battery can be removed for immediate use.

With no battery inserted, continuous lighting of the green charge control LED 19 indicates that the mains plug is plugged into the socket and that the battery charger is ready for operation.

Battery Temperature below 0°C and above 45°C

Continuous lighting of the red LED 18 indicates that the battery temperature is not within the rapid-charging temperature

range of 0°C - 45°C. As soon as the allowable temperature range is reached, the battery charger automatically switches to rapid charging.

When the battery is not within the allowable temperature range, the red battery LED lights up when inserting the battery into the battery charger.

No charging procedure possible

If a different malfunction of the charging procedure is present, this will be indicated through flashing of the red charge control LED 18.

The charging procedure can not be started and the battery cannot be charged (see "Troubleshooting").

Charging Advice

With continuous or several repetitive charging cycles without interruption, the charger can warm up. This is not meaningful and does not indicate a technical defect of the battery charger.

A significantly reduced working period after charging indicates that the battery is used and must be replaced.

Battery Cooling (Active Air Cooling)

The fan control integrated in the battery charger controls the temperature of the inserted battery. When the battery temperature is above 30°C, a fan cools down the battery to the optimal charging temperature. The switched-on fan produces a fan noise.

The battery temperature is within the optimal charging temperature range when the fan is not running, or the fan may possibly be defective. In this case, the charging time of the battery extends.

Assembly

Do not connect the battery and/or the isolator key before the product is completely assembled. Ensure the cables are not trapped when folding/unfolding top/bottom handles. Do not drop the handles.

Handle assembly A

1 2 Insert the handle bottom 6 into the holes provided and secure with the screws.

Note: The handle top 3 is height adjustable. Fix handles in desired position I or II.

Attach the handle top 3 with the bolts and wing nuts 22 to the handle bottom 6.

Note: Ensure that the cable clips supplied are used to fix the cable to the handle.

Inserting the Battery 3

Lift the battery cover latch 23 and lift up battery cover 7.

Fit battery 8, when correctly fitted a "click" will be heard. Fit the isolator key 24 as shown. Ensure correct location. If the mower is not going to be used immediately, fit isolator key 24 as shown in the storage position.

Close battery cover 7.

Removing the Battery

Lift the battery cover latch 23 and lift up battery cover 7.

Remove isolator key 24, refit in storage position.

Lift the battery cover latch 23.

Remove the battery 8.

Snap together the grassbox

Rotak 34/37 LI C

Snap the grassbox top on the grassbox bottom by pushing all the "snap fits" together around the edges starting at rear and working towards the front.

Rotak 43 LI D

Snap the grassbox bottom halves together by pushing all the "snap fits" together around the edges starting at rear and working towards the front. Snap together both top and bottom half of the grassbox.

Grassbox fitting/removing

Lift the deflector guard 5 and hold up, fit or remove the grassbox 4.

For non grass collection the mower can be used without the grassbox 4 in position, with the deflector guard 5 in the down position.

Adjusting the Cutting Height F

• Stop, release switch lever and wait until the motor stops before adjusting height. The blades continue to rotate after the machine is switched off, a rotating blade can cause injury. Caution - do not touch the rotating blade.

For the first cutting of the season, a high cutting adjustment should be selected.

The lawnmower can be set to 7 cutting heights between 35 mm and 70 mm.

For this purpose, press the height of cut lever 12 inwards then lift or push down the mower until required height is selected.

The lawnmower may be used to cut down to 20mm by removing the blanking plate 25 as shown.

Using the height of cut between 20 - 30mm will shorten the battery duration.

Operation

Starting

The blade continues to rotate for a few seconds after the machine is switched off. Allow the motor/blade to stop rotating before switching "on" again. Do not rapidly switch off and on.

Note: To aid starting push handle down to lift front wheels.

Fit the isolator key 24.

Starting

1 sec start

Press and hold the safety button 2. - Squeeze the switch lever 1 towards the handle.

Release the safety button 2.

Note: There is a short delay in the motor starting after engaging the switch lever 1.

Stopping

Release the switch lever 1.

If the mower is not going to be used immediately, fit isolator key 24 as shown in the storage position.

The machine is fitted with a blade brake. This safety feature stops the blade from rotating in a few seconds.

Mowing

Protect the battery from heat, for example continuous exposure to sun radiation and fire.

Product will not function if temperature is below 0°C or above 45°C.

Do not leave the battery in the product in direct sunlight.

When working, do not allow the motor to labour, particularly in heavy conditions.

When the motor labours, the speed of the motor drops and you will hear a change in the motor sound. When this occurs, stop working, release the switch lever 1, and raise the height of cut.

Failure to do so will reduce area of cut and/or could damage the product or battery.

The grass combs 11 allow a very close cut to the wall or edge. Beware of running combs 11 into objects while cutting close to walls/edges.

Working Advice

Battery Charge-control Indication (see main figure)

The battery 8 is equipped with a charge-control indicator 14 which indicates its charge condition. The charge-control indicator 14 consists of 3 green LEDs.

Press the button 13 to actuate the charge-control indicator 14. After approx. 5 seconds, the charge-control indicator goes out automatically.

The charge condition can also be checked when the battery is removed.

LED Indicators	Battery Capacity
Continuous lighting of 3 green LEDs	≥ 2/3
Continuous lighting of 2 green LEDs	≥ 1/3
Continuous lighting of 1 green LED	≤ 1/3
Flashing of 1 green LED	Reserve

When no LED lights up after actuating the button 13, the battery is defective and must be replaced.

For safety reasons, the charge condition of the battery can only be checked when the product is at a standstill.

During the charging procedure, the three green LEDs light up one after the other and briefly go out. The battery is fully charged when the three green LEDs light up continuously. The three LEDs go out again approx. 5 minutes after the battery has been fully charged.

Temperature Control Indicator (see main figure)

The red LED 15 signals that the battery or the electronics of the product (with battery inserted) are not within the optimum temperature range. When this occurs the product will not operate or not at full capacity.

Temperature Control of the Battery

The red LED 15 flashes when pushing button 13 or pressing the On/Off switch 1 (when the battery is inserted): The battery is not within the temperature range for operation of -10°C to +60°C.

The battery switches off at a temperature above 70°C until the optimum temperature range is reached again.

Temperature Control of the Product Electronics

The red LED 15 lights up continuously when pressing the On/Off switch 1: The temperature of the product electronics is below 5°C or above 75°C.

At a temperature above 90°C, the electronics of the product switch off until the temperature is within the allowable temperature range again.

Area of Cut (Battery Duration)

The area of cut (battery duration) depends on lawn conditions, grass density, moisture content, grass length and height of cut.

Switching the machine on and off frequently during cutting will also reduce the area of cut (battery duration).

To improve the area of cut (battery duration) it is recommended to cut more frequently, raise the cutting height and walk at a normal pace.

The example below shows the impact of conditions on run time, for one battery.

Cutting Conditions

Very light, dry grass	Light, dry grass	Medium, dense grass
6cm 4cm	8cm 4cm	15cm 4cm
Area of cut (Rotak 34 LI)

Charging procedure

The charging procedure begins as soon as the mains plug of the charger is inserted into the socket outlet and the battery is inserted into the charging slot 16.

The INHOBaUNHOHbM MeTOd 3aprAKn automatically determines the state of charge of the battery. Depending on its temperature and voltage, the charging process is carried out with an optimal current.

This extends the battery life. When stored in the charging device, the battery is always fully charged.

Meaning of the indicator elements

Battery is not charging

If charging is not possible for any reason, disconnect the mains plug.

The charging process does not start, and charging of the battery is not possible (see 'Troubleshooting').

Charging instructions for the battery

During continuous or multiple charging cycles without interruption, the charging device may heat up. This, however, does not pose a danger and does not indicate a technical malfunction of the power tool.

A significant reduction in operating time after charging indicates that the batteries are aging and that they need to be replaced.

Battery cooling (Active Air Cooling)

The built-in fan control in the charging device monitors the temperature of the installed battery. If the battery temperature exceeds 30°C, the fan cools it to the optimal temperature for charging. The activated fan emits characteristic noises during operation.

If the fan does not start, the battery temperature is within the optimal temperature range and the fan is not needed. In this case, the charging time of the battery is extended.

Миганne 1 зeльноу сbvETOДИОДa	PeЗерВ

If after pressing the button 13 none of the LEDs light up, this means that the battery is defective and must be replaced.

Safety instructions: Checking the battery charge level may only be carried out when the device is switched off.

During the charging process, the three green LEDs light up and go out for a short time. The battery is fully charged when the three green LEDs are lit continuously. Approximately after 5 minutes of charging, the three green LEDs go out.

Temperature control indicator (see main figure)

The red LED of the temperature control indicator signals that the battery or the device electronics (with the battery inserted) are outside the permissible temperature range. In this case, the device does not work or does not work at full power.

Battery temperature control

The red LED flashes when button 13 or switch 1 is pressed (with the battery inserted): the battery temperature is outside the working range of -10 °C to +60 °C.

At temperatures above 70 °C, the battery is switched off for the time required to return to the permissible temperature range.

Device electronics temperature control

The red LED 15 lights up when switch 1 is pressed and stays on without flashing: the temperature of the device electronics is below 5 °C or above 75 °C.

At temperatures above 90 °C, the electronics are switched off for the time required to return to the permissible temperature range.

Mowing efficiency

(Battery operating time)

Mowing efficiency

(Battery operating time) depends on the properties of the lawn, e.g., grass density, moisture, grass length, as well as the mowing height.

Frequent switching on and off of the unit during mowing also reduces mowing efficiency (battery operating time).

To increase the efficiency of mowing (duration of battery operation), it is recommended to mow slowly, increase the cutting height, and move at a moderate speed.

The example below shows the relationship between cutting height and mowing efficiency relative to the battery charge.

Warning! Before any maintenance or cleaning, switch off the device and disconnect the plug from the power supply and remove the battery. The same applies if the power cord is damaged, cut, or tangled. The device may continue to rotate for a few seconds. Be careful - do not touch the blade until it stops.

Charging the battery

Pay attention to the mains voltage: The voltage of the power source must match the data on the device's rating plate. Devices designed for 230 V can also operate on 220 V/240 V.

Use only the supplied charger. This charger is designed for the lithium-ion battery used in your device.

The battery has a temperature monitoring element that allows charging only in the temperature range from 0°C to 45°C. This ensures a long service life of the battery.

Note: The battery is supplied partially charged. To ensure that the battery reaches its full capacity, before using the device for the first time, the battery must be fully charged in the charger.

The lithium-ion battery can be charged at any time without shortening its service life. Interrupting the charging process does not damage the battery.

The lithium-ion battery is protected against deep discharge when used in the device. When the battery is discharged, the device switches off via a protective circuit, and it no longer works.

The battery charger is designed for charging the battery. It can be used as a charger.

Charging

Plug the charger into the power outlet. The charger will start charging the battery.

Thanks to the intelligent charging algorithm, the charger automatically detects the battery charge level and charges it with an optimal current depending on the battery temperature and voltage.

It preserves the battery, and if the battery is stored in the charger, it will be fully charged.

Indicator functions

The charging status is indicated by indicator 18 or 19:

Charging

During fast charging, the green indicator 19 lights up.

When charging is complete, the green indicator lights up continuously. The battery is fully charged when the green indicator lights up continuously. After a while, if the battery is fully charged, the green indicator will go out again.

Note: Fast charging may not occur if the battery temperature is outside the permissible temperature range for charging, see the section "Technical data".

Battery charged

The continuous green light of indicator 19 indicates that the battery is fully charged.

A short beep sounds for about 2 seconds, indicating that the battery is fully charged.

After that, the battery can be removed and used immediately.

If the battery is not installed, the green indicator light 19 will flash to indicate that the device is not installed in the socket and the device is not ready for operation.

Battery temperature is 0°C or below 45°C

Flashing red indicator light 18 indicates that the battery temperature is

The battery is outside the temperature range for fast charging of 0°C - 45°C. When the temperature returns to the permissible charging range, charging will automatically resume at fast charging.

If the battery temperature is outside the permissible charging range, the red battery indicator will light up when the battery is inserted into the charger.

Charging is in progress

During charging, the red indicator light 18 flashes.

Charging cannot start and the battery is not charging (see "Troubleshooting").

Charging instructions

With continuous charging or with charging cycles that repeat one after another without interruption, the charger may heat up. However, this is not dangerous and does not indicate a technical malfunction of the charger.

A short charging time indicates that the battery is worn out and needs to be replaced.

Battery cooling (Active Air Cooling)

The built-in fan in the charger controls the temperature of the inserted battery. If the battery temperature exceeds 30°C, the battery

is cooled by the fan to the optimal charging temperature. The activated fan creates noise.

If the fan does not turn on, it means that the battery temperature is within the optimal range or the fan is faulty. In this case, the charging time of the battery is increased.

If you do not want to mow the grass, the lawn mower can be used without the grass catcher 4. In dry weather, the deflector 5 must be fitted.

Adjusting the mowing height

Before adjusting the mowing height, stop, release the handle and wait until the motor has stopped. Raising the motor while it is still running can cause injury. Be careful not to touch the blade while it is still rotating.

By turning the lever 25, as shown in the illustration, the mowing height can be changed up to 20 mm.

When mowing at a height of 20-30 mm, the working speed of the battery should be reduced.

Operation

Starting work

Press the start button and the motor will start after a few seconds. To switch off, release the handle and wait until the motor and blade have stopped. Do not switch on again immediately after switching off.

Insert the plug into the socket, press the handle, and adjust the cutting height.

Reinsert the spreader 24.

Mowing

1 sec start

Press the lock button 2 and hold it pressed. Tilt the handle 1 to the handle. Release the lock button 2.

Note: After releasing the handle 1, the motor starts with a slight delay.

Switching off

Release the handle 1.

If you will not use the lawn mower, put the spreader 24 into the reserve position, as shown in the picture.

The motor of the lawn mower is braked. This brake stops the blade within a few seconds.

Charging

Protect the battery from heat, e.g., from direct sunlight, and also from moisture. The device does not work at temperatures below 0°C or above 45°C!

If the device is exposed to direct sunlight, do not charge the battery in the device.

After charging, the device can be used under normal conditions without overloading the motor. The number of mowing operations is reduced and the motor heats up. In this case, stop, release the handle 1, and set a higher mowing height. In extreme cases, the capacity (service life of the battery) may be shortened and/or the battery may be damaged.

Thanks to the blades 11, you can mow grass close to walls and corners. When mowing grass, be careful not to touch the blades 11 with other objects.

Battery charge indicator (see figure B)

The battery is fitted with a battery charge indicator 14 that shows the charge level of the battery. The battery charge indicator 14 consists of 3 green LEDs.

Press the battery charge indicator button 13 to activate the battery charge indicator 14. After about 5 seconds, the battery charge indicator goes out automatically.

The charge level can also be checked when the battery is removed.

Мнагнny 1 зеленого сbvITLOAOda	peЗерВ

If after pressing the button 13 none of the LEDs lights up, the battery is defective and must be replaced.

When using the tool, the battery charge level can also be checked with the tool switched on.

When charging, the three green LEDs light up one after the other. The battery is fully charged when the three green LEDs light up continuously. After about an hour after the battery is fully charged, the three green LEDs go out again.

Temperature control indicator (see figure B)

The red LED of the temperature control indicator 15 signals that the battery or the tool electronics (with integrated battery) is outside the optimal temperature range. In this case, the tool does not work or does not work at full power.

Battery temperature control

The red LED 15 lights up when pressing the button 13 or when switching on the tool 1 (with integrated battery): the battery is outside the permissible range for charging or the working temperature range of -10 °C to +60 °C.

At temperatures above 70 °C, the tool switches off until the temperature is within the permissible range again.

Tool electronics temperature control

The red LED 15 lights up continuously when the tool is switched on: the temperature of the tool electronics is below 5 °C or above 75 °C.

At an ambient temperature of 90°C, the electronics will shut down until the temperature returns to the permissible range.

Mowing time (battery runtime)

Mowing time (battery runtime) depends on the quality of the grass, e.g., its density, moisture, grass height, and cutting height.

Frequent starting and stopping during grass cutting also significantly reduces the mowing time (battery runtime).

To optimize the mowing time (battery runtime), it is recommended to regularly mow the grass, adjust the cutting height, and work at the appropriate speed.

The chart below shows the relationship between cutting height and mowing time depending on the battery charge level.

Check that the switch is in the ON position.

The blades may not be able to cut the grass and may be damaged.

Battery care

Warning! Before servicing or cleaning the device, turn off the switch, remove the battery, and remove the grass clippings. Wear protective gloves when handling or working near sharp blades.

Observe the requirements for the charging voltage: The voltage of the charging source must match the data printed on the rating plate of the power tool. Power tools marked with 230 V can also be charged with 220 V/240 V.

Use only the charger supplied. Only this charger has the parameters suitable for the battery pack of your power tool.

The battery pack has a temperature control that allows charging only in the range between 0°C and 45°C. This increases the service life of the battery pack.

Note: The battery pack is supplied partially charged. To ensure full capacity of the battery pack, charge it completely with the charger before first use.

The lithium-ion battery pack can be charged at any time without shortening its service life. Interrupting the charging process does not damage the battery pack.

Battery pack charged

The continuous green light of the LED 19

Indicates that the battery pack is fully charged.

During charging, after approx. 2 seconds, an acoustic signal sounds, which indicates the completion of charging of the battery pack.

When this happens, the battery pack can be removed for use.

The continuous green light of the LED 19, when a battery pack is inserted, indicates that the tool is switched on and the charger is ready for operation.

Temperature of the battery below 0°C or above 45°C

The red light on the charger is flashing

Indicates that the battery temperature is

outside the range for fast charging from 0°C - 45°C. When the

battery temperature is within this interval, the charging device switches to fast charging.

If the battery temperature is outside the permissible range for charging, the charging device's red light flashes.

Charging is not possible

If there is another reason why the charging process cannot start, this is indicated by the flashing of the red light 18.

The charging process cannot be started and charging of the battery is not possible (see "Troubleshooting").

Charging indicator

During fast charging, respectively during repeated consecutive charging of the battery without a pause, the charging device may heat up. This is normal and does not indicate a technical defect in the charging device.

Significantly reduced operating time after charging indicates that the battery is worn out and must be replaced.

Cooling of the battery (Active Air Cooling - active air cooling)

The built-in battery cooling system monitors the temperature. If the battery temperature rises above 30° C, the fan turns on, which optimizes the charging temperature. The running fan generates a slight noise.

If the fan does not work, the battery temperature is either optimal for charging or the fan is damaged. In the latter case, the charging time of the battery is extended.

Connect the battery charger to the electrical winch eBA cEA only when the power tools are switched off. When lowering and raising the upper part of the winch, be careful not to damage the protective cable. Do not allow the remote control to fall.

Mounting the remote control A

1 2 Place the lower part of the remote control 6 in the provided opening for the switch and secure it with the screws for the lamp.

Note: The upper part of the remote control 3 can be adjusted in height. Mount it in the highest position.

Mount the upper part of the remote control 3 using the screws N and the clamping brackets 22 to the lower part 6.

Note: Secure the protective cable to the remote control with the clamps included in the kit.

Installing the battery charger

1 Turn the locking screw for the battery charger 23 counterclockwise and lift the cover 7. Insert the battery charger 8 so that it engages without play (click). Make contact with the connector for the electrical winch 24, as shown in the figure. Make sure the connector is in the correct socket. When not using the remote control directly, connect the contact through the connector of the electrical winch 24 by placing it in the parking position.

Close the cover of the battery charger 7.

Removing the battery charger

Turn the locking screw for the battery charger 23 counterclockwise and lift the cover 7.

Disconnect the connector of the electrical winch 24 and place it in the parking position.

Turn the locking screw for the battery charger 23 counterclockwise.

Remove the battery charger 8.

If the tool does not light up at all when the trigger is pressed, the battery pack is damaged and must be replaced.

If the work light 15 lights up when the trigger switch 1 is pressed with continuous light: the temperature of the electronics of the power tool is below 5°C or above 75°C.

At a temperature of 90°C, the electronics of the power tool switch off until the temperature returns to the permissible operating temperature range.

Operating time (working time of the battery pack)

The cutting productivity (working time of the battery pack) depends on the properties of the material being cut. The frequency, humidity, length, and also the cutting height.

The cutting productivity (working time of the battery pack) also decreases with frequent switching on and off of the power tool during cutting.

To optimize the cutting productivity (working time of the battery pack), it is recommended to cut more frequently, increase the cutting height, and work at a moderate speed.

The diagram below shows the relationship between the cutting height and the productivity with one charge of the battery pack.

To increase the working time, you can purchase a replacement battery pack from your power tool dealer.

Troubleshooting

The table below shows symptoms of faults and how you can help yourself if the power tool stops working normally. If you cannot detect and fix the problem by following the instructions in the table, contact your service center for power tools.

CAUTION: Before you start searching for and detecting faults, switch off the power tool and disconnect the battery pack from the power tool.
