■ 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.

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 ten‐

sion side (2).

4.8.2

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 dur‐

ing 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.

4.8.3

Felling

WARNING

■ Inexperienced users cannot assess the dan‐

gers 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 neighbor‐

ing 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 inju‐

ries.

► 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 inju‐

ries.

► 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 con‐

trolled manner.

► Stop the felling operation and use a cable

winch or suitable vehicle to pull the tree to

the ground.
