enough to direct the fall of the tree for

as long as possible.

WARNING

Never walk in front of a tree that has

been notched.

Make the felling cut (D) from the other

side of the tree and 1.5"- 2.0”(3-5cm}

above the edge of the notch (C)

{Figure5-1B}.

Never saw completely through the

trunk-Always leave a hinge.The hinge

guides the tree,If the trunk is completely

cut through, control over the felling

direction is lost.

Insert a wedge or felling lever in the cut

well before the tree becomes unstable

and starts to move.This will prevent the

guide bar from binding in the felling cut

if you have misjudged the faliing

direction.Make sure no bystanders have

entered the range of the falling tree

before you push it over.

WARNING

Before making the final cut, always

recheck the area for bystanders,

animals or obstacles.

FELLING CUT:

1. Use wooden or plastic wedges (G)

to prevent binding the bar or chain

(H) in the cut.Wedges also control

felling (Figure S-IC),

2. When diameter of wood being cut is

greater than the bar length, make 2

cuts as shown (Figure 5-1D).

WARNING

As the felling cut gets close to the

hinge, the tree should begin to

fall.When tree begins to fall, remove

saw from cut, stop engine, put chain

saw down, and leave area along retreat

path (Figure 5-lA).

5-2. LIMBING

Limbing a tree is the process of

removing the branches from a fallen

tree.Do not remove supporting limbs (A)

until after the log is bucked (cut) into

lengths (Figure 5-2A).

Branches under tension should be cut

from the bottom up to avoid binding the

chain saw.

WARNING

Never cut tree limbs while standing on

tree trunk.

5-3. BUCKING

Bucking is cutting a fallen iog into

lengths.To make sure the performance,

the diameter of wood would be

recommended to be the limit of max.

15cm or 6”, Make sure you have a

good fiiting and stand uphill of the log

when cutting on stoping ground. It

possible, the log should be supported

so that the end to be cut off Is not

resting on the ground, ft the log is

supported at both ends and you must

cut in the middle, make the undercut.

This will prevent the log from pinching

the bar and chain, Be careful that the

chain dies not cut into the ground when

bucking as this causes rapid dulling of

the chain.

When bucking on a slope, always stand

on the uphill side.

1. Log supported along entire

length:Cut from top (overbuck),

being careful to avoid cutting into the

ground (Figure 5-3A}.

2, Log supported on one(1) endiFirst,

cut from bottom (urtderbuck) 1/3

diameter of log to avoid splintering.

Second, cut from above (overbuck)

to meet first cut and avoid pinching

(Figure 5-3B).
