well away from the chain. Move only when the trunk is
between you and the chain. Watch out for spring back
of limbs under tension.
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. 28)

If the log is lying on the ground make a boring cut to avoid
cutting into the ground. Finish with a bottom cut. (Fig. 30)
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.
