Overcutting

Undercutting

Undercutting

involves cutting on the under-

side of the log with top of saw against the log.

When undercutting use light upward pres-

sure. Hold saw firmly and maintain control.

The saw will tend to push back toward you.

WARNING:

Never turn saw upside

down to undercut. The saw cannot be con-

trolled in this position.

Always make your first cut on the compres-

sion side of the log. The compression side of

the log is where the pressure of the log’s

weight is concentrated.

BUCKING WITHOUT A SUPPORT

S

Overcut through

1/3

of the diameter of the

log.

S

Roll the log over and finish with a second

overcut.

S

Watch for logs with a compression side to

prevent the saw from pinching. See il-

lustrations for cutting logs with a compres-

sion side.

BUCKING USING A LOG OR

SUPPORT STAND

S

Remember your first cut is always on the

compression side of the log.

(Refer to the following illustrations for your

first and second cut)

S

Your first cut should extend

1/3

of the

diameter of the log.

S

Finish with your second cut.

LIMBING AND PRUNING

WARNING:

Be alert for and guard

against kickback. Do not allow the moving

chain to contact any other branches or objects

at the nose of the guide bar when limbing or

pruning. Allowing such contact can result in

serious injury.

WARNING:

Never climb into a tree to

limb or prune. Do not stand on ladders, plat-

forms, a log, or in any position which can cause

you to lose your balance or control of the saw.

IMPORTANT POINTS

S

Work slowly, keeping both hands firmly

gripped on the saw. Maintain secure footing

and balance.

S

Watch out for springpoles. Springpoles are

small size limbs which can catch the saw

chain and whip toward you or pull you off bal-

ance. Use extreme caution when cutting

small size limbs or slender material.

S

Be alert for springback. Watch out for

branches that are bent or under pressure.

Avoid being struck by the branch or the

saw when the tension in the wood fibers is

released.

S

Keep a clear work area. Frequently clear

branches out of the way to avoid tripping

over them.

LIMBING

S

Always limb a tree after it is cut down. Only

then can limbing be done safely and prop-

erly.

S

Leave the larger limbs underneath the felled

tree to support the tree as you work.

S

Start at the base of the felled tree and work

toward the top, cutting branches and limbs.

Remove small limbs with one cut.

S

Keep the tree between you and the chain.

Cut from the side of the tree opposite the

branch you are cutting.
