4 Safety Precautions

Working

4.7.1 Cutting
WARNING
￭ The user cannot concentrate on the work in certain
situations. The user may trip, fall and be seriously injured.
► Work calmly and carefully.
► If light and visibility are poor: Do not use your saw.
► Operate the chain 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 heights: Use a lift
bucket or a safe platform.
￭ The rotating saw chain can cut the operator. This can
result in serious injuries.
► Do not touch the rotating saw chain.
￭ The rotating chain becomes hot and expands. If the chain
is not cooled sufficiently and retensioned, it can come off
the guide bar or break. This can result in serious injuries
and damage to property.
► Use special 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 and contact your STIHL servicing dealer.
￭ 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. This can result in
serious injuries.
► Wait for the chain to come to a standstill.

WARNING
￭ 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).
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.
