English
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).
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.
4.7.2 Limbing
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.
4.7.3 Felling
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.
► 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 may 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 may 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.
