LIMBING THICK BRANCHES
When limbing thick branches, the guide bar may get pinched easily.
Branches under tension often snap up, so cut troublesome branches
in small steps. Apply the same principles as for cross cutting. Think
ahead and be aware of the possible consequences of all your
actions.
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. 22)

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. 23)

If the log is lying on the ground make a boring cut to avoid cutting into
the ground. Finish with a bottom cut. (Fig. 24)

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. 25)

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. 26)
