Cordless Chain Saw WG368E WG368E.9

after it is felled.

An escape path should be planned and cleared as

necessary before cuts are started. The escape path should

extend back and diagonally to the rear of the expected line

of fall.

Before felling is started, consider the natural lean of

the tree, the location of larger branches and the wind

direction to judge which way the tree will fall.

Remove dirt, stones, loose bark, nails staples, and wire

from the tree.

Notching undercut: Make the notch (x-w) 1/3 the

diameter of the tree, perpendicular to the direction of

falls as make the lower horizontal notching cut ﬁrst. This

will help to avoid pinching either the saw chain or the

guide bar when the second notch is being made.

Felling back cut: Make the felling back cut (Y) at least

50 mm higher than the horizontal notching cut. Keep the

felling back cut parallel to the horizontal notching cut.

Make the felling back cut so enough wood is left to act

as a hinge. The hinge wood keeps the tree from twisting

and falling in the wrong direction. Do not cut through

the hinge.

As the felling gets close to the hinge the tree should

begin to fall. If there is any chance that the tree may

not fall in desired direction or it may rock back and

bind the saw chain, stop cutting before the felling back

cut is complete and use wedges of wood, plastic, or

aluminum to open the cut and drop the tree along the

desired line of fall.

When the tree begins to fall remove the chain saw from

the cutting, stop the motor, put the chain saw down, and

then use the retreat path planned. Be alert for overhead

limbs falling and watch your footing.

To complete the felling operation, drive a wedge (Z) into

the horizontal cut.

Beware of falling branches when the tree starts to move.

LIMBING A TREE (See Fig. Q)

Limbing is removing the branches from a fallen tree.

When limbing leave larger lower limbs to support the

log off the ground. Remove the small limbs in one cut as

illustrated. Branches under tension should be cut from

the bottom up to avoid binding the chain saw.

BUCKING A LOG (See Fig. R)

Bucking is cutting a log into lengths. It is important to

make sure your footing is ﬁrm and your weight is evenly

distributed on both feet. When possible, the log should

be raised and supported by the use of limbs, logs or
