CROSS CUTTING/BUCKING
Before starting to cut through the log, try to imagine what is going to
happen. Look out for stresses in the log and cut through it in such a
manner that the guide bar will not get pinched.
CROSS CUTTING LOGS, PRESSURE ON TOP
Take a fi rm stance. Begin with an upper cut. Do not cut too deeply,
about 1/3 of the log diameter is enough. Finish with a bottom cut.
The saw cuts should meet. (Fig. 23)

THICK LOG, LARGER THAN GUIDE BAR LENGTH
Begin by cutting on the opposite side of the log. Pull the saw towards
you, followed by previous procedure. (Fig. 24)
If the log is lying on the ground make a boring cut to avoid cutting into
the ground. Finish with a bottom cut. (Fig. 25)
WARNING
KICKBACK DANGER
Do not attempt a boring cut if you are not properly trained. A
boring cut involves the use of the nose of the guide bar and can
result in kickback.
CROSS CUTTING LOGS, PRESSURE ON BOTTOM
Take a fi rm stance. Begin with a bottom cut. The depth of the cut
should be about 1/3 of the log diameter.
Finish with an upper cut. The saw cuts should meet. (Fig. 26)

THICK LOG, LARGER THAN GUIDE BAR LENGTH
Begin by cutting on the opposite side of the log. Pull the saw towards
you, followed by previous procedure. Make a boring cut if the log is
close to the ground. Finish with a top cut. (Fig. 27)
WARNING
KICKBACK DANGER
Do not attempt a boring cut if you are not properly trained. A
boring cut involves the use of the nose of the guide bar and can
result in kickback. (Fig. 28)
IF THE SAW GETS STUCK
Stop the engine. Raise the log or change its position, using a thick
branch or pole as a lever. Do not try to pull the saw free. If you do,
you can deform the handle or be injured by the saw chain if the saw
is suddenly released.
