Frequently Asked Questions - LIION Power 37 Wolf Garten

How to charge the battery of the Wolf Garten LIION Power 37 lawn mower?

Remove the safety key and take the battery out of the compartment. Connect the battery to the supplied charger, then plug the charger into a 230 V outlet. The red LED indicates charging, the green LED signals charging complete. Charging time is approximately 5-6 hours for a completely discharged battery.

What cutting height to choose for a lawn?

The recommended cutting height is 40-50 mm. For wet grass, mow higher. Use the adjustment lever to set the desired height. Avoid cutting more than 20 mm at once to avoid overloading the mower.

How to use the mulching function?

Activate the mulching function by setting the CCM switch to MULCH. First remove the collection bag. Mow slowly and overlap passes. Mulching is ideal for dry, not too tall grass. Do not use it on moss or weeds.

How to clean the mower after use?

Before cleaning, remove the safety key and battery. Use a brush or cloth to remove grass. Never clean the mower with a water jet. Regularly clean the mulching flap and level indicator holes with a hand brush.

What to do if the mower does not start?

Check that the safety key is inserted, the battery is charged (flashing red LED means battery empty), and the collection bag is correctly installed. If the engine still does not start, consult the "How to remedy malfunctions" chapter of the manual.

How to replace the mower blade?

Remove the safety key and battery. Wear protective gloves. Unscrew the central screw with a torque wrench (torque 6-7 Nm). Replace the blade with a Wolf Garten original part. Resharpening should be done by a specialized workshop to avoid imbalance.

How to transport the mower safely?

Before transport, stop the engine and remove the safety key. Let the engine cool down for approx. 30 minutes. For transport in a vehicle, secure the mower firmly to prevent slipping. Do not tilt the device more than necessary.

How to empty the collection bag?

When the bag is full, the safety flap closes automatically. Stop the engine, remove the safety key. Lift the hood, unhook the bag, empty it, and put it back. Make sure the hooks are properly inserted into the frame openings.

What are the main safety instructions to follow?

Read the entire manual before use. Never mow with people or pets nearby. Wear safety shoes and close-fitting clothing. Before any maintenance, remove the safety key. Caution: the blade still rotates after stopping. Do not mow on slopes greater than 20%.

How to adjust the handle height?

Unfold the lower part of the handle and tighten the two knobs. Set the desired height, then unfold the upper part and secure it with the wing nuts. Ensure the cable is not kinked. The mower must be off and the safety key removed.

Instructions for the use of WOLF-Garten battery-powered mowers

The area that can be mown by your battery-powered mower is dependent on various factors. These are: Type of lawn

Battery-powered lawnmowers are suitable for lawns the are mown frequently, normally, and, to a certain extent, for lawns that have not been cut for a while after holidays. The surface area that can be mown does however decrease in the order given above. Battery-powered mowers are not suitable for infrequently-mown meadows or similar.

Lawn structure

The area that can be mown decreases in proportion to the density of the grass. The mowing capability is lowest on extremely dense grass, e. g. golf greens.

Lawn condition

The condition of the lawn (dry, damp with dew, wet) has a major influence on the area of lawn which can be mowed. If the lawn is dry, this will give the maximum area which can be mowed. If the lawn is wet, more energy is required for the mowing and collection and thus this is the condition where the area which can be mowed is at a minimum.

Mowing/walking speed

The walking speed influences the duration of mowing and therefore the area that can be covered. We therefore recommend rapid mowing. The mowing path should not be covered twice if possible and the overlap of mowing tracks should be kept as minimal as possible. Frequently switching the mower on and off likewise decreases the battery's power.

Charging the battery

Caution! The charger must only be operated in dry rooms!

General charging instructions

To prolong the service life of the battery, observe the following instructions:

●Before first use, the battery needs to be charged for about 5-6 hours.
- If the battery voltage is too low, the lawnmower switches off automatically. In such a case, recharge the battery.
●The Lithium iron battery must also be recharged before prolonged periods of non-use, for example at the beginning of winter.
●The charging time is 5-6 hours for a battery that is completely empty.
●The Lithium ion battery can be recharged at any charge level, and charging can be interrupted and resumed without any damage to the battery (no memory effect).

1. Remove the contact key K
2. Release the battery cover by pushing it down L.
3. Remove the battery from the recess M
4. Connect the battery to the charger N.
5. Connect the charger to the mains socket (230 V \~) N .

Instructions for the handling of the charger:

●Red LED is on: Battery is being charged
●Green LED is on: Charge process completed
- If the charger is connected to a power socket without a battery, the LEDs are off.
- In order to prolong the life the battery, it should not be charged for a period longer than two days.

Cut / Collect (LI-ION POWER 37, LI-ION POWER 40)

Activate cut/collect function U

Attention! Rotary cutter blade

Undertake adjustments on the equipment only after the motor is switched off and the cutting tool has come to a standstill.

- Do not start the motor until your feet are at a safe distance from the cutting tool.

1. Remove the grass collecting bag.
2. Turn the switch to "CUT/COLLECT".
3. Hang up the collection bag if necessary.
4. Start the motor.

Mulch (LI-ION POWER 37, LI-ION POWER 40)

„Mulching“ is a process in which the grass is finely chopped by a special cutting system and then deposited on the ground. The result is that the grass does not have to be collected and disposed of. „Mulching“ also prevents the lawn from drying out.

Instructions for mulching

We recommend:

• Depending on the growth of grass, mulch 1 – 2 x per week
  ●The grass should not be too high nor too wet!
  ●Go slow while mulching
  ●Take care that the blade channels do overlap.
  ●Do not cut grass more than 20 mm.

Note:

Mulching is not advisable in case of moss-affected or entangled grass, because the cut material stays on the moss surface and/or entanglement and thus cannot be absorbed by the ground.

● Regularly scarify and manure the lawn.

Activating the mulch function U

Attention! Rotary cutter blade

Undertake adjustments on the equipment only after the motor is switched off and the cutting tool has come to a standstill.

- Do not start the motor until your feet are at a safe distance from the cutting tool.
