Cutting
WARNING
■ Always work within calling distance of others
in case help is needed.
► Make sure than persons outside the work
area are within calling distance.
■ The user cannot concentrate on the work in
certain situations. The user can lose control of
the saw, stumble or fall and be seriously
injured.
► Work calmly and carefully.
► If light and visibility are poor: Do not use
your saw.
► Operate the saw alone.
► Do not work above shoulder height.
► Watch out for obstacles.
► Stand on the ground while working and
keep a good balance. If it is necessary to
work at a height and the chainsaw is used
with a cable connected to a power supply:
Use a lift bucket.
► If you begin to feel tired: Take a break.
■ The rotating saw chain can cut the operator.
This can result in serious injuries.
► Do not touch the rotating saw chain.
► If the saw chain is blocked by an object:
Switch off the chainsaw, engage the chain
brake and remove the battery. Then
remove the object causing the blockage.
■ The rotating chain becomes hot and expands.
If the chain is not lubricated sufficiently or not
re-tensioned at regular intervals, it may come
off the guide bar or break. This can result in
serious injuries and damage to property.
► Use special chain oil.
► 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

injuries and damage to property.
► Stop work, remove the battery and contact
your STIHL servicing 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.
