• Make an initial cut on the underside of the branch
before cutting through the branch. This will prevent
tearing of the bark, which could lead to slow healing
and cause permanent damage to the tree. The cut
should not be deeper than 1/3 of the branch
thickness to prevent jamming. Keep the chain
running while you withdraw the cutting attachment
from the branch to prevent it jamming.
• Use the harness to support the weight of the
machine and make it easier to handle.
• Make sure you have a firm footing and that you can
work without being hampered by branches, stones
and trees.
