9. Notes on working with the

machine

9.1 General points
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.
0478 121 9919 A - EN
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
regularly (STIHL specialist dealer).

9.2 Working area for operator

● For safety reasons, the operator
must stay within the working area
behind the handlebar when the motor 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. (
11.5).
9.3 Correct motor load
Do not switch on the lawn mower in tall
grass. Select a higher cutting height
setting if the motor is difficult to start.
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.
9.4 If the mowing blade blocks
Switch off the motor immediately and
disconnect the mains plug. Then eliminate
the cause of the fault.
9.5 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,
11
– inadequate cleaning of the cooling air
guide (inlet slots),
– mowing blade is blunt or worn,
– unsuitable or excessively long electric
cable – voltage loss (

Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
(depending on the ambient temperature)
( 11.).

10. 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.
