9.3 If the mowing blade blocks
Switch off the motor immediately and
disconnect the mains plug. Then eliminate
the cause of the fault.
9.4 Thermal motor overload protection
If an overload of the motor occurs during
operation, the built-in thermal overload
protection device automatically switches
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),
– mowing blade is blunt or worn,
– unsuitable or excessively long electric
cable – voltage loss (
Ö
11.1).
Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
(depending on the ambient temperature)
(
Ö
11.).
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.

An integrated motor run-down brake
shortens the run-down time until the blade
stops.
