► Check oil level in tank regularly during cut‐
ting work. Before the oil tank runs empty:
Fill up with chain oil.
► Check chain tension regularly during cutting
work. If chain tension is insufficient: Ten‐
sion the chain.
■ If the behavior of the saw changes during
operation or feels unusual, it may no longer be
in a safe condition. This can result in serious
injuries and damage to property.
► Stop work and contact your STIHL dealer
for assistance.
■ Saw vibrations may occur during operation.
► Wear gloves.
► Take regular breaks.
► If signs of circulation problems occur: Seek
medical advice.
■ Sparks may occur if the rotating chain makes
contact with a hard object. Sparks may cause
a fire in an easily combustible location. This
can result in serious or fatal injuries and dam‐
age to property.
► Do not work in an easily combustible loca‐
tion.
■ Note that the saw chain continues to rotate for
a short period after you release the trigger.
The rotating saw chain can cut the user. This
can result in serious injuries.
► Wait for the chain to come to a standstill.

Felling
WARNING
■ Inexperienced users cannot assess the dan‐
gers of felling a tree. This can result in serious
or fatal injuries and damage to property.
► If you have any queries: Do not fell the tree
yourself.
■ Parts of the tree being removed and branches
can fall on bystanders or objects during the
felling operation. This can result in serious or
fatal injuries and damage to property.
► Determine direction of fall so that the area
in which the part of the tree being removed
falls is clear.
► Do not allow bystanders, children or ani‐
mals within 2.5 tree lengths of the work
area.

0000-GXX-7574-A0
Kickback can be caused for the following rea‐
sons:
–
The rotating saw chain in the upper quadrant
of the bar nose makes contact with a hard
object and is suddenly braked.

nose.
The chain brake cannot prevent kickback.
WARNING

■ If kickback occurs, the saw can be thrown up
in the direction of the operator. Due to the spe‐
cial handle design (closely spaced handles)
there is a risk of the operator losing control of
the chainsaw and sustaining serious or fatal
injuries.
► Hold the saw firmly with both hands.
