OPERATION
BUCKING WITH A WEDGE (Fig. 34)
If the wood diameter is large enough for you to insert a soft
bucking wedge (B) without touching the chain, you should
use the wedge to hold the cut open to prevent pinching.
BUCKING LOGS UNDER STRESS (Fig. 35)
(D) LOG SUPPORTED AT ONE END.
(C) LOG SUPPORTED AT BOTH ENDS.
Make the first bucking cut (E) 1/3 of the way through the
log and finish with a 2/3 cut (F) on the opposite side.
As you cut the log, it will tend to bend. The saw can
become pinched or hung in the log if you make the first
cut deeper than 1/3 of the diameter of the log.
Give special attention to logs under stress (G) to prevent
the bar and chain from pinching.
OVERBUCKING (Fig. 19)
Begin on the top side of the log with the bottom of the saw
against the log; exert light pressure downward. Note that
the saw will tend to pull away from you (A).
UNDERBUCKING (Fig. 19)
Begin on the under side of the log with the top of the saw
against the log; exert light pressure upward.
During underbucking, the saw will tend to push back
at you (B). Be prepared for this reaction and hold the saw
firmly to maintain control.
LIMBING AND PRUNING (Fig. 36)
Work slowly, keeping both hands on the saw with a
■
firm grip. Maintain secure footing and balance.
Keep the tree between you and the chain while
■
limbing. Cut from the side of the tree opposite the
branch you are cutting.
Do not cut from a ladder: this is extremely dangerous.
■
Leave this operation for professionals.
Do not cut above chest height as a saw held higher is
■
difficult to control against kick-back.
WARNING
Never climb into a tree to limb or prune. Do not
stand on ladders, platforms, a log, or in any
position which may cause you to lose your
balance or control of the saw.
When pruning trees it is important not to make the flush
■
cut next to the main limb or trunk until you have cut off
the limb further out to reduce the weight.
This prevents stripping the bark from the main member.

1. Underbuck the branch 1/3 through for your first
cut (A).
2. Overbuck the branch to drop it (B).
3. Finish by cutting smoothly and neatly against the
main member (C) so the bark will grow back to seal
the wound.
WARNING
If the limbs to be pruned are above chest height,
hire a professional to perform the pruning.
CUTTING SPRING POLES (Fig. 37)
A spring pole (A) is any log, branch, rooted stump,
or sapling which is bent under tension by other wood so
that it springs back if the wood holding it is cut or
removed. On a fallen tree, a rooted stump has a high
potential of springing back to the upright position during
the bucking cut to separate the log from the stump.
Watch out for spring-poles; they are dangerous.
WARNING
Spring poles are dangerous and could strike the
operator causing the operator to lose control of
the chainsaw. This could result in severe or fatal
injury to the operator.
MAINTENANCE
ASSEMBLING THE BAR AND CHAIN (Fig. 3
& 38 - 47)
DANGER
Never start the engine before installing the
guide bar, chain, drivecase cover, and clutch
drum. Without all these parts in place, the clutch
can fly off or explode exposing the user to
possible serious injury.
WARNING
To avoid serious personal injury, read and
understand all the safety instructions in
this section.
1. Always place the switch in the stop "O" position
before you work on the saw.
2. Make sure the chain brake is not set by pulling the
chain brake lever/hand guard towards the front
handle to the RUN position (A).
3. Wear gloves when handling the chain and bar.
These components are sharp and may contain burrs.
