• Cut large branches in sections so that you
have better control over where they fall.
• Never cut through the swelling at the root
of the branch as this will slow down healing
and increase the risk of fungal attack.
• Use the stop at the base of the
cutting head to provide support during
cutting. This will help prevent the cutting
attachment from "jumping" on the branch.
• 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.
To check the chain lubrication
• Check the chain lubrication periodically
during operation. Aim the tip of the bar
at a light colored surface about 8 in. (20
cm) away. After 1 minute running at 75%
throttle you should see a distinct line of oil
on the light surface.
