GENERAL CUTTING INSTRUCTIONS

Adequate lubrication of the saw chain is

essential at all times to minimize friction with

the guide bar.

Never starve the bar and chain of oil.

Running the saw with too little oil will

decrease cutting efficiency, shorten saw

chain life, cause rapid dulling of chain, and

cause excessive wear of bar from

overheating. Too little oil is evidenced by

smoke, bar discoloration or pitch build-up.

NOTE: Saw chain stretches during use,

particularly when it is new, and it will

Your chain saw is equipped with an

automatic clutch driven oiler system. The

oiler automatically delivers the proper

amount of oil to the bar and chain. As the

engine speed increases, so does the oil flow

to the bar pad. There is no flow adjustment.

The oil reservoir will run out at approximately

the same time as the fuel supply runs out.

WARNING:

Don't put pressure on

the saw when reaching the end of the cut.

The pressure may cause the bar and chain

to rotate. If the rotating chain strikes some

other object, a reactive force may cause

moving chain to strike the operator.

Felling is the term for cutting down a tree.

Small trees up to 6-7 inches (15-18cm) in

diameter are usually cut in a single cut.

Larger trees require notch cuts. Notch cuts

determine the direction the tree will fall.

Normally felling consists of 2 main cutting

operations, notching (C) and making the

felling cut (D).

Start making the upper notch cut (C) on the

side of the tree facing the felling direction

(E). Be sure you don t make the lower cut

too deep into the trunk.

The notch (C) should be deep enough to

create a hinge (F) of sufficient width and

strength. The notch should be wide enough

to direct the fall of the tree for as long as

possible.

NOTE:Direction of fall (B) is controlled by the

notching cut. Before any cuts are made,

consider the location of larger branches and

natural lean of the tree to determine the way

the tree will fall.

WARNING:

A retreat path (A) should

be planned and cleared as necessary before

cuts are started. The retreat path should

extend back and diagonally to the rear of the

expected line of fall, as illustrated in

Fig.11A.

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 inches (3-5 cm) above

the edge of the notch (C) (Fig.11B)

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 guidebar from

binding in the felling cut if you have

misjudged the falling direction. Make sure no

bystanders have entered the range of the

falling tree before you push it over.

WARNING:

Do not cut down a tree

during high or changing winds or if there is a

danger to property. Consult a tree

professional. Do not cut down a tree if there

is a danger of striking utility wires; notify the

utility company before making any cuts.

CAUTION:

If felling a tree on sloping

ground, the chain saw operator should keep

on the uphill side of the terrain, as the tree is

likely to roll or slide downhill after it is felled.
