4 Safety Precautions
￭ 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 cutting work.
Before the oil tank runs empty: Fill up with chain oil.
► Check chain tension regularly during cutting work. If
chain tension is insufficient: Tension 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, 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 damage to property.
► Do not work in an easily combustible location.
￭ 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.

￭ The guide bar can be pinched when cutting wood that is
under tension. The user can lose control of the saw and
be seriously injured.
► Make a relieving cut in the compression side (1) first,
then perform bucking cut at the tension side (2).
DANGER
￭ Working near live electric cables can result in accidental
contact with the chain and damage the cables. This can
result in serious or fatal injuries.
► Do not work near live electric cables.
4.7.2 Limbing
WARNING
￭ If the underside of the felled tree is limbed first, it will no
longer be supported on the ground by branches. The tree
can move during cutting work. This can result in serious or
fatal injuries.
► Cut through large limbs on the underside of the tree only
after it has been bucked.
► Do not stand on the log while limbing it.
￭ A branch may fall to the ground during limbing. The user
may trip, fall or be seriously injured.
► Limb from the base to the crown of the tree.
