8.5 Level indicator
The flow of air generated by the
blade raises level indicator (1). The
flow of air stops when the grass catcher
box is full. If the flow of air is too low, level
indicator (1) returns to its resting state.
This is a prompt to empty the grass
catcher box.
The functionality of the level indicator is
restricted if the flow of air is impaired.
External influences such as wet, dense or
high grass, low cutting levels,
contamination or the like can impair the
flow of air and the functionality of the level
indicator.

The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
9.1 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.
9.2 Motorstop lever
The lawn mower is equipped with a
motorstop device.
The engine stops when the motorstop
lever is released during running operation.
The engine and blade come to a standstill
within 3 seconds.
Measuring the run-on time
Following engine start-up, the blade
rotates and a wind noise is audible. The
run-on time corresponds to the duration of
the wind noise after the engine stops. This
can be measured using a stopwatch.
A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
