10.3 Correct motor load
Do not switch on the lawn mower in tall
grass or at the lowest cutting height.
The lawn mower load must never cause
the motor speed to drop significantly.
If the speed drops, select a higher cutting
height setting and/or reduce the rate of
feed.
10.4 If the mowing blade blocks
Switch off the motor immediately and
disconnect the safety plug. Then eliminate
the cause of the fault.

off the motor.
Causes for an overload:
– mowing excessively high grass or
cutting height adjusted too low,
– excessive rate of feed,
– inadequate cleaning of the cooling air
guide (inlet slots).
Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
