ground and that are above your chest height.

Cutting Operation

• When cutting a branch do not cut flush to the trunk to
prevent that the branch when falling will rip the trunk's
bark.
• Make the first cut 1/3 deep with regards to the branch
diameter. Then, make a second 2/3 cut in the opposite
side.
• Finish cutting the branch with a third cut flush to the
trunk to allow bark growth and sealing the cut.
• If the branch is too big cut sections to prevent a violent
detachment.
Poles
• Pole is a trunk, branch or young tree that has been bent
by another trunk or branch pressure accumulating tension
which is released with great force if the pressure is
released.
DANGER • Poles are very dangerous because may
hit the operator causing severe injuries and / or losing
control on the chain saw. Stay always alert to this
possibility.
