| 1st Cut |
Undercutting involves cutting on the un- derside of the log with top of saw against the log. When undercutting use light up- ward pressure. Hold saw firmly and main- tain control. The saw will tend to push back toward you.
WARNING: Never turn saw upside down to undercut. The saw cannot be controlled in this position.
Always make your first cut on the com- pressions side of the log. The compres- sion side of the log is where the pressure of the log’s weight is concentrated.

BUCKING WITHOUT A SUPPORT
SOvercut through 1/3 of the diameter of the log.
SRoll the log over and finish with a sec- ond overcut.
S Watch for logs with a compression side to prevent the saw from pinching. See illustration above for cutting logs with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
SRemember your first cut is always on the compression side of the log. (Refer to the illustration below for your
first and second cut)
S Your first cut should extend 1/3 of the diameter of the log.
SFinish with your second cut.

LIMBING AND PRUNING
WARNING: Be alert for and guard against kickback. Do not allow the mov- ing 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 lad- ders, platforms, a log, or in any position which can cause you to lose your bal- ance or control of the saw.
IMPORTANT POINTS
S Watch out for spring poles. Spring poles are small size limbs which can whip toward you or pull you off bal- ance. Use extreme caution when cut- ting small size limbs.
S Be alert for spring back from any branches that are bent or under pres- sure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released.
S Frequently clear branches out of the way to avoid tripping over them.
LIMBING
SLimb a tree only after it is cut down. 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 tree between you and the chain.
