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 the 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.

another trunk or branch pressure accumulating tension
which is released with great force if the pressure is
released.

hit the operator causing severe injuries and / or losing
control on the chainsaw. Stay always alert to this
possibility.
