4.8 Maintenance and repairs
Before beginning cleaning, adjustment,
repair and maintenance operations:
● Park the machine on firm and level
ground
● Stop the engine and allow it to cool
down
● Detach the spark plug
socket.
Caution – risk of injury!
Keep the spark plug socket
away from the spark plug; an inadvertent
ignition spark can result in fires or electric
shocks.
Inadvertent contact between the spark
plug and the spark plug socket can result
in unwanted starting of the engine.
RM 545 VE: Additionally remove the
battery.
Allow the machine to cool down before
working on or around the 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.
Cleaning:
The complete machine must be cleaned
thoroughly following use. (Ö 12.2)
Empty the fuel tank (e.g. by running it
empty) before placing the machine in the
cleaning position.
Remove accumulated clipping deposits
using a stick. Clean the underside of the
mower with water and a brush.
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.

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

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.

particular the blade fastening screw) are
securely tightened so that the machine is
in a safe operating condition.
Replace damaged exhaust silencers and
