increase the risk of injury from the 
cutting attachment rotating while the 
engine is idling.
When using metal cutting attachments
STIHL recommends the use of original 
STIHL metal cutting attachments. They 
are specifically designed to match your 
model and meet your performance 
requirements.
Metal cutting attachments rotate at very 
high speed. The forces that occur act on 
the machine, the attachment and the 
material being cut.
Sharpen metal cutting attachments 
regularly as specified.
Unevenly sharpened metal cutting 
attachments cause out-of-balance 
which can impose extremely high loads 
on the machine and increase the risk of 
breakage.
Dull or improperly sharpened cutting 
edges can put a higher load on the 
cutting attachment and increase the risk 
of injury from cracked or broken parts.
Inspect metal cutting attachments for 
cracks or warping after every contact 
with hard objects (e.g. stones, rocks, 
pieces of metal). To reduce the risk of 
injury, remove burrs and other visible 
build-ups of material (use a file) because 
they may become detached and be 
thrown at high speed during operation.
To reduce the above-mentioned risks 
when using a metal cutting attachment, 
never use a metal cutting attachment 
with a diameter larger than specified. It 
must not be too heavy. It must be 
manufactured from materials of 
adequate quality and its geometry must 
be correct (shape, thickness).
To reduce the risk of injury, a metal 
cutting attachment not manufactured by 
STIHL must not be heavier, thicker, 
have a different shape or a diameter 
larger than the largest metal cutting 
attachment approved by STIHL for this 
power tool model.
Vibrations
Prolonged use of the power tool may 
result in vibration-induced circulation 
problems in the hands (whitefinger 
disease).
No general recommendation can be 
given for the length of usage because it 
depends on several factors.
The period of usage is prolonged by:
– Hand protection (wearing warm 
gloves)
– Work breaks
The period of usage is shortened by:
– Any personal tendency to suffer 
from poor circulation (symptoms: 
frequently cold fingers, tingling 
sensations).
– Low outside temperatures.
– The force with which the handles 
are held (a tight grip restricts 
circulation).
Continual and regular users should 
monitor closely the condition of their 
hands and fingers. If any of the above 
symptoms appear (e.g. tingling 
sensation in fingers), seek medical 
advice.
Maintenance and Repairs
Service the machine regularly. Do not 
attempt any maintenance or repair work 
not described in the instruction manual. 
Have all other work performed by a 
servicing dealer.
STIHL recommends that you have 
servicing and repair work carried out 
exclusively by an authorized STIHL 
servicing dealer. STIHL dealers are 
regularly given the opportunity to attend 
training courses and are supplied with 
the necessary technical information.
Only use high-quality replacement parts 
in order to avoid the risk of accidents 
and damage to the machine. If you have 
any questions in this respect, consult a 
servicing dealer.
STIHL recommends the use of original 
STIHL replacement parts. They are 
specifically designed to match your 
model and meet your performance 
requirements.
To reduce the risk of injury from 
unintentional engine startup, always 
shut off the engine and disconnect the 
spark plug boot before performing any 
repairs, maintenance or cleaning work. – 
Exception: Carburetor and idle speed 
adjustments.
Do not turn the engine over on the 
starter with the spark plug boot or spark 
plug removed since there is otherwise a 
risk of fire from uncontained sparking.
To reduce the risk of fire, do not service 
or store your machine near open flames.
Check the fuel filler cap for leaks at 
regular intervals.
