The upper part of the grass catcher
box features a level indicator (1).
The flow of air that is created by the rotary
movement of the mowing blade and is
responsible for filling the grass catcher box
raises the level indicator (2):
The grass catcher box is filled with

9. Notes on working with the

machine

9.1 General points

9
Risk of injury!
Untangle any knots in the cable
immediately.
Guide the electric cable behind you
when mowing. Electric cables can
be inadvertently cut when mowing
and present a tripping hazard. They
therefore involve a high accident
risk. For this reason, mow so that
the electric cable is always visible
in the area of grass that has already
been cut.
To ensure a perfect, thick lawn, mow
regularly and keep the grass short.
Do not cut the lawn too short in hot, dry
conditions as it will dry out or burn in the
sun and become unsightly.
The cutting pattern will be better with a
sharp blade than with a blunt one; the
blade should therefore be sharpened
10
regularly (STIHL specialist dealer).
9.2 Correct motor load
Do not switch on the lawn mower in tall
grass or at the lowest cutting height.
The lawn mower load must never cause
the motor speed to drop significantly.
If the speed drops, select a higher cutting
height setting and/or reduce the rate of
feed.
11.5).
9.3 If the mowing blade blocks
Switch off the motor immediately and
disconnect the mains plug. Then eliminate
the cause of the fault.

9.4 Thermal motor overload protection

If an overload of the motor occurs during
operation, the built-in thermal overload
protection device automatically switches
off the motor.
Causes for an overload:
– mowing excessively high grass or
cutting height adjusted too low,
– excessive rate of feed,
– inadequate cleaning of the cooling air
guide (inlet slots),
– mowing blade is blunt or worn,
– unsuitable or excessively long electric
cable – voltage loss ( 11.1).
