Self-Propulsion Lever; Motorstop Lever - Stihl RM 248 Manuel D'utilisation

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.
Always observe the safety distance
provided by the handlebar.
● The lawn mower must only be operated
by one person. Other persons must
keep out of the danger area. (
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.
10.2 Stopping the engine

● Release self-propulsion lever (1). Self-
propulsion is switched off and the lawn
mower comes to a standstill. The
engine continues to run.
10.4 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.
