WORKING INFORMATION
Observe the local regulations on operating lawnmowers.
- Remove all foreign objects from the lawn prior to mowing
- Keep others away from dangerous areas.
- Use the mower only if visibility is good
- Guide the machine at a walking pace.
- Mow only with a sharp cutting blade
- Do not mow over obstacles (e.g. branches, roots of trees).
- Mow only across slopes. Do not use the mower up or down slopes and not on slopes with more than a slant of 20 degrees.
- Added care must be taken on slopes when changing direction
Tips for mowing
- Start mowing as close to the socket as possible.
- Always keep the extension cable on the previously mowed lawn area.
- Constant cutting height 3-5 cm, do not cut more than half the height of the lawn.
- Do not overload the lawn mower! If the motor speed is greatly reduced due to long, heavy grass, raise the cutting height and mow several times.
- Mow in the morning or late afternoon to protect the freshly cut lawn from drying out.
- Mow the lawn twice per week during the strong growing phases. Mow less during periods of less rain.
Mulching with the mulching kit (option)
With mulching, the cuttings are not collected and remain on the grass. The
mulch protects the ground from drying out and provides it with nutrients. The
best results are achieved by regular cutting of approx. 2 cm. Only young grass
with soft blades will decompose quickly.
- Height of grass before mulching: maximum 8 cm
- Height of grass after mulching: minimum 4 cm
Adapt your walking speed to the mulching and do not go too quickly.

CAUTION!
Risk of injury due to rotating parts! Remove or replace the mulch kit only
while the motor is switched off and the cutting blade has stopped.
- Remove the grass catcher
- Lift up the baffle plate and insert the mulch kit into the discharge chute.
- Mulch kit must audibly engage
If the mulch kit does not engage, the mulch kit and cutting blade can be damaged.
Removing the mulch kit

- Release the locking on the mulch kit. (4b-2)
- Pull out the mulch kit.
Wheel drive (option)
Adjusting the Bowden cable

running, the corresponding Bowden cable must be readjusted.
CAUTION!
Risk of injury!
Only adjust the Bowden cable when the motor is switched off.
- Turn the adjustment part on the Bowden cable in the direction of the arrow.
- To check the adjustment, start the motor and switch on the wheel drive.
- If the wheel drive still does not function, bring the lawn mower to a service centre or an authorized specialist firm.
Oiling the drive pinion
