–before checking, cleaning or working on 
the machine,
–before freeing a blocked scarifying unit 
or unblocking the discharge chute,
–if there has been a collision with an 
obstacle. Inspect the machine for 
damage and perform the necessary 
repairs before re-starting and using the 
machine,
–if the machine vibrates excessively. In 
this case the machine must be checked 
immediately.
In the event of excessive vibration or after 
a collision with an obstacle, check the 
machine, in particular the scarifying unit 
(blade shaft, blades, spacer bushings and 
fastening), the housing and the discharge 
flap for damage and loose parts and carry 
out the necessary repairs before re-
starting and working with the machine. If 
you do not have the appropriate expertise, 
have the necessary repairs carried out by 
a specialist dealer (STIHL recommends 
STIHL specialist dealers).
4.7 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.
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 11.2)
Remove accumulated clipping deposits 
using a stick. Clean the underside of the 
machine 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.
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.
Risk of injury through defective 
parts!
Strong vibration is normally an 
indication of a fault.
In particular, the machine must not 
be operated with a damaged or 
bent scarifying unit (blade shaft, 
blades, spacer bushings and 
fastening).
Risk of injury!
Pulling the recoil starter rope starts 
the blades rotating. Always ensure 
sufficient distance between the 
blades and your body, particularly 
your hands and feet, when you pull 
the recoil starter rope.
