may cause damage to the engine and
other machine parts, resulting in
expensive repairs.
Allow the machine to cool down before
performing maintenance operations on the
gearbox, engine, exhaust manifold or
muffler in particular. Temperatures of
80° C and above can be reached.
Danger
of burns!
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.
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.
Cleaning:
The complete machine must be cleaned
thoroughly following use. (
Ö 12.2)
Remove accumulated clipping deposits
using a stick. Clean the underside of the
machine with water and a brush.
Do not use aggressive cleaning agents.
These can damage plastics and metals,
impairing the safe operation of your STIHL
machine.
The underside of the machine (everything
below the guard plate) can be cleaned
using a high-pressure cleaner or steam
cleaner. Maintain a distance of at least 1 m
and never direct the water jet directly at the
bearing points or seals – especially the
seal between the gearbox housing and
guard plate.
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.
Ensure that all nuts, pins, bolts and screws
are securely tightened, so that the
machine is in a safe operating condition.
Never alter the basic setting of the engine
or run at excessive engine speeds.
Components or guards that are removed
for maintenance operations must be
properly reinstalled immediately.
When replacing the work tools (hoes),
ensure that the correct hoe type and hoe
combination are installed – only those
versions approved by STIHL are
permitted.
4.8 Storage for prolonged periods
without operation
Allow the engine to cool before storing the
machine in an enclosed space.
Store the machine with empty fuel tank
and the fuel reserve in a lockable and well-
ventilated room.
Ensure that the machine is protected from
unauthorised use (e.g. by children).
Never store the machine with petrol in the
tank inside a building. The resulting petrol
fumes could come into contact with naked
flames or sparks and could be ignited.
