● Park the machine on firm and level
ground
● Stop the engine and allow it to cool
down
● Detach the spark plug
socket.

shocks.
Inadvertent contact between the spark
plug and the spark plug socket may result

Direct contact with engine oil can be
dangerous. Engine oil must not be spilled.
STIHL recommends leaving the task of
topping up engine oil or performing engine
oil changes to a STIHL specialist dealer.
Cleaning:
The complete machine must be cleaned
thoroughly following use. ( 11.2)
Never use high-pressure cleaners and do
not clean the machine under running water
(e.g. using a garden hose).
Do not use aggressive cleaning agents.
These can damage plastics and metals,
impairing the safe operation of your STIHL
machine.
In order to prevent fire hazards, keep the
area around the air vents, cooling ribs and
the area of the exhaust free from
e.g. grass, straw, moss, leaves or
escaping grease.
Maintenance operations:
Only maintenance operations described in
this instruction manual may be carried out.
Have all other work performed by a
specialist dealer.
If you do not have the necessary expertise
or auxiliary equipment, please always
contact a specialist dealer.
STIHL recommends that you have
maintenance operations and repairs
performed exclusively by a STIHL
specialist dealer.
STIHL specialist dealers regularly attend
training courses and are provided with
technical information.
Only use tools, accessories or
attachments approved for this machine by
STIHL or technically identical parts.
Otherwise, there may be a risk of
accidents resulting in personal injury or
damage to the machine. If you have any
questions, please consult a specialist
dealer.
The characteristics of original STIHL tools,
accessories and spare parts are optimally
adapted to the machine and the user's
requirements. Genuine STIHL spare parts
can be recognised by the STIHL spare
parts number, by the STIHL lettering and,
if present, by the STIHL spare parts
symbol. On smaller parts, only the symbol
may be present.
For safety reasons, fuel-carrying
components (fuel line, fuel cock, fuel tank,
tank cap, connections, etc.) must be
checked regularly for damage and leaks
and replaced by a technician if necessary
(STIHL recommends STIHL specialist
dealers).
Always keep warning and information
stickers clean and readable. Damaged or
missing stickers must be replaced by new,
original plates from your STIHL specialist
dealer. If a component is replaced with a
new component, ensure that the new
component is provided with the same
stickers.
Only perform work on the cutting unit when
wearing protective gloves ( 4.3) and
exercising extreme care.
Ensure that all nuts, pins and screws,
especially all the cutting unit screws, are
securely tightened, so that the machine is
in a safe operating condition.
Check the entire machine for wear or
damage on a regular basis, particularly
before extended periods when the
machine is not in use (e.g. over winter).
For safety reasons, worn or damaged
parts must be replaced immediately to
ensure that the machine is always in a safe
operating condition.
