Level indicator:
The centre of the anti-dust screen is lifted
slightly through the air flow which is
generated by the rotary motion of the
mowing blade and is responsible for filling
the grass catcher bag.
When the grass catcher bag is full, this
flow of air is reduced and the anti-dust
screen drops down onto the grass catcher
bag.
Emptying the grass catcher bag:
● Disengage the mowing blade. (Ö 10.3)
● Detach the grass catcher bag. (Ö 7.7)
● Hold the grass catcher bag by
handle (2) and nylon strap (3) sewn
onto the back and empty it.
● Attach the grass catcher bag again.

11.1 Cleaning the machine
Maintenance interval:
After each use
Treating the machine carefully will protect
it against damage and extend its service
life.
Never spray water (high-pressure cleaner)
onto engine components, seals, electrical
parts or bearing points. This may result in
damage and expensive repairs.
Do not use aggressive cleaning agents.
These cleaners can damage plastics and
metals, impairing the safe operation of
your STIHL machine.
If you are unable to remove the dirt with
water using a brush or a cloth, STIHL
recommends the use of a special cleaner
(e.g. STIHL special cleaner).
Detach accumulated cutting deposits in
the housing and in the ejection chute
beforehand using a stick.
Cleaning position:
● Park the machine on level, flat and solid
ground.
● Remove the grass catcher box. (Ö 7.7)
● Close the tank ventilation screw.
(Ö 7.5)
● Set the maximum cutting height at the
left and right rear wheels. (Ö 7.3)
● Remove screw (1) together with
washer (2).
● Hold the handlebar until notch (3) is
above bore (4) in the housing.
● Install screw (1) with washer (2) firmly
enough that the handlebar is securely
fixed in the service position.
● Lift up the machine at the front, open
the discharge flap and fold down the
handlebar to the rear. Check that the
machine is stable.
After cleaning, place the machine on all
4 wheels, locate the handlebar in the
working position once more and set the
desired cutting height.
11.2 Wheels
The wheel bearings are maintenance-free.
Risk of injury!
Always disengage the mowing
blade before emptying. (Ö 10.3)
Take weight into account!
A completely filled grass catcher
bag can weigh up to 22 kg.
Avoid damage to the machine!
Always empty the grass catcher
bag in good time in order to prevent
the mowing channel from becoming
obstructed. Obstructions can block
the mowing blade and lead to
unnecessary wear of the blade
brake clutch.
11. Maintenance
Risk of injury!
Carefully read the section "For your
safety" (Ö 4.), particularly the
subsection "Maintenance and
