4.7 Working
4.7.1 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 chainsaw 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.
►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 and re-tensioned at regular
intervals, it man 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, remove the battery and contact your STIHL
servicing dealer for assistance.
￭Saw vibrations may occur during operation. ►
Wear gloves.

English 4 Safety Precautions
54 0458-701-9921-E
►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.
Felling
WARNING
￭Inexperienced users cannot assess the dangers 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.
￭A tree 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
tree falls is clear.
►Do not allow bystanders, children or animals within 2.5
tree lengths of the felling site.
►Remove broken or dead branches from the tree crown
before felling.
►If broken or dead branches cannot be removed from the
crown: Do not fell the tree.
►Observe tree crown and crowns of neighboring trees
and keep clear of falling branches.

￭When the tree falls the trunk can break or spring back in the
direction of the user. This can result in serious or fatal
injuries.
►Plan an escape path sideways behind the tree.
►Walk backwards along the escape path and observe the
falling tree.
►Do not walk backwards down slopes.
￭Obstacles in the work area and on the escape path can
hinder the user. The user may trip and fall. This can result
in serious or fatal injuries.
►Remove all obstacles from the work area and escape
path.
￭If you cut into or through the hinge, stabilizing strap or
holding strap too soon, the intended direction of fall cannot
be controlled or the tree can fall prematurely. This can
result in serious or fatal injuries and damage to property.
►Do not cut into or through the hinge.
►Cut through the stabilizing strap or holding strap last.
►If the tree begins to fall too soon: Abandon the felling cut
and retreat along the escape.
￭Kickback can occur if the rotating chain in the upper
quadrant of the bar nose makes contact with a hard felling
wedge and is suddenly braked. This can result in serious or
fatal injuries.
►Use aluminum or plastic felling wedges.
￭If the tree does not fall all the way to the ground or gets
caught on another tree, the operator cannot finish the
operation in a controlled manner.
►Stop the felling operation and use a cable winch or
suitable vehicle to pull the tree to the ground.
4.8 Reactive Forces
4.8.1 Kickback
Kickback can be caused for the following reasons:
–The rotating saw chain in the upper quadrant of the bar
nose makes contact with a hard object and is suddenly
braked.
–The rotating saw chain is pinched at the bar nose.
The chain brake cannot prevent kickback.
￭If kickback occurs, the saw can be thrown up in the
direction of the operator. The operator can lose control of
the saw and be seriously or fatally injured. ► Hold the saw
firmly with both hands.
