8.2 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.
Risk of injury!
If the run-on time of the blade
exceeds this delay, stop using the
machine and take it to your
specialist dealer.
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.
9. Notes on working with the
machine
A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using a sharp mowing blade – mowing
blade should therefore be sharpened
regularly (specialist dealer).
– Changing the cutting direction regularly.

9.1 Working area for operator

● For safety reasons, the operator
must stay within the working area
behind the handlebar when starting the
engine and when the engine is running.

10. Operating the machine

10.1 Starting the engine

Avoid damage to the machine!
Do not start the engine in tall grass
or at the lowest cutting height. This
makes starting difficult.
Thanks to the fixed throttle setting,
the engine always operates at the
optimum working speed after
starting.
● Press motorstop lever (1) to the
handlebar and hold.
● Slowly pull out recoil starter rope (2) to
the point of compression resistance.
Then pull vigorously and quickly to
arm's length. Slowly return recoil starter
rope (2) again so that it is rolled up
again.
Repeat the procedure until the engine
starts.
