9. 1 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.
1 0. 1 General information on mulching
During mulching, the cut grass is chopped
up several times through a special air flow
guidance system in the mower blade area
and then blown back into the turf. The
clippings remain on the lawn.
Danger of pinching!
The handlebar can fold down or
retract inadvertently when the
quick-clamping device/handlebar
screw fastening is released.
For this reason, always hold the
handlebar with one hand while
releasing the fastening.
