Warning – fire hazard!
Avoid overloading the mowing deck
drive. Overloading may lead to
constant slipping of the V-belt and
consequently to a fire hazard due to
overheating.
Unusual running noise, e.g. a
"squealing" (slipping noise) of the
V-belt, indicates overloading. For
this reason, never mow in high
grass when the discharge chute is
blocked or the grass catcher box is
full; use a mulching kit (special
accessory) if necessary.
The mowing deck, particularly the
V-belt area, must always be kept
free of combustible material (grass,
leaves, etc.). It should also be
cleaned regularly to prevent a fire
hazard.
Preventing blockage of the discharge
chute
If the discharge chute becomes blocked
with grass, reduce the driving speed. This
may be too high in relation to the lawn
conditions. The slide of the level sensor
should be fully pulled out. (
If the problem persists, the probable cause
is damaged or worn highlift blade. Replace
the mowing blade.
Furthermore, the mowing deck, discharge
chute and mowing blade should be
cleaned after each use to prevent the
accumulation of grass deposits.
Fertilisation
Mowing the grass deprives the ground of
permanent nutrients, which can be
returned by using a high-grade, long-term
lawn fertiliser. Usually, fertilising three
times per mowing season is necessary.
For this purpose, the lawn should be dry,
82
so that the fertiliser does not stick to the
grass blades and burns them. It is then
better to water the lawn, which results in
the fertiliser being flushed off the grass
blades. (Observe manufacturer's
instructions for use.)
Natural fertilising is possible using lawn
clippings. This is made possible by the use
of the mulching kit. The mulching kit is
available as a special accessory and is not
included in the standard equipment.
(Further information is available from your
STIHL specialist dealer.)
Ground-conserving working
The most important factors for ground-
conserving working are operating
technique and ground moisture.
In order to achieve clean mowing results,
the driving speed must be adapted to the
condition of the grass to be mowed (height
and density) and to the moisture of the
lawn.
Executing curves that are too tight
increases the loading on the turf and leads
to poor mowing results, particularly on wet
grass, as the wheels sink into the soft

grass.

11. Safety devices

The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Risk of injury!
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; STIHL recommends STIHL
specialist dealers.
To start the engine, the following
conditions must always be fulfilled:
– the mowing deck must be disengaged,
– the brake pedal must be pressed or the
parking brake engaged.
The engine is switched off if the user
– leaves the driver's seat with the mowing
deck engaged,
– lifts the grass catcher box or removes
the deflector (special accessory) with
the mowing deck engaged,
– leaves the driver's seat without
engaging the parking brake.
Integrated blade run-down brake:
Following disengagement, the mowing
blades come to a standstill after 5
seconds at the latest.
Note
Following engagement of the
mowing deck, the mowing blade
turns and a wind noise is audible.
The run-on time corresponds to the
duration of the wind noise following
disengagement. This can be
measured using a stopwatch.
