11.1 Safety devices
The lawn mower is equipped with safety
devices, which prevent inadvertent contact
with the mowing blade and with ejected
clippings.
These include the housing, discharge flap,
grass catcher box and correctly installed
handlebar.

the safety plug is inserted (
11.3 Two-hand operation
The motor can only be switched on by
pressing and holding the ON button with
the right hand and then pulling the
motorstop lever to the handlebar with the
left hand.
11.4 Motor run-down brake
When the motorstop lever is released, the
mowing blade comes to a complete
standstill in less than three seconds.
An integrated motor run-down brake
shortens the run-down time until the blade
stops.
Measuring run-down time
Following motor start-up, the blade rotates
and a wind noise is audible. The run-down
time corresponds to the duration of the
wind noise after the motor stops. This can
be measured using a stopwatch.
