CAUTION:
•
Keep all parts of the body away from the saw
chain when the motor is operating.
•
Hold the chain saw firmly with both hands when
the motor is running.
•
Do not overreach. Keep proper footing and
balance at all times.
Bring the spike bumper into contact with the branch to
be cut before switching on. Cutting without bringing the
spike bumper into contact with the branch may cause
the guide bar to wobble, resulting in injury to operator.

When cutting thick branches, first make a shallow
undercut and then make the finish cut from the top.

If you try to cut off thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.

If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the
spike a little lower and finish the cut by raising the
handle.

For bucking cuts, rest the spike bumper shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the top handle to raise the saw and the front one to
guide it. Use the spike bumper as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the spike
bumper further down the timber and raise the front
handle again.
When making several cuts, switch the chain saw off
between cuts.

CAUTION:
•
If the upper edge of the bar is used for cutting, the
chain saw may be deflected in your direction if the
chain becomes trapped. For this reason, cut with
the lower edge, so that the saw will be deflected
away from your body.
