Overcutting

Overcutting begins on the top side of the log with the saw against the log. When overcut- ting use light downward pressure.

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.

BUCKING WITHOUT A WARNING: Never turn saw upside down to undercut. The saw cannot be con- trolled in this position.

LIMBING AND PRUNING

Using a support stand 2nd Cut WARNING: Be alert for and guard against kickback. Do not allow the moving chain to contact any other branched or objects at the nose of the guide bar when limbing or pruning. Allowing such contact can result in serious injury.

LIMBING AND PRUNING 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 Watch out for springpoles. Use extreme caution when cutting small size limbs. Slen- der material may catch the saw chain and be whipped toward you or pull you off balance.

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.

SKeep a clear work area. Frequently clear branches out of the way to avoid tripping over them.

LIMBING

SAlways 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.

SStart at base of the felled tree and work to- ward the top, cutting branches and limbs.

Remove small limbs with one cut.

SKeep the tree between you and the chain

as much as possible.

SRemove larger, supporting branches with the cutting techniques described in BUCK-

ING WITHOUT A SUPPORT.

SAlways use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.

PRUNING

LIMBING WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job.
