Never throw cuttings into the household garbage
can – they can be composted!
Never stand directly under the branch you are cut-
ting – be wary of falling branches. Note that a branch
may spring back at you after it hits the ground!
Cutting sequence
To allow branches a free fall, always cut the lower branch-
es first. Prune heavy branches (large diameter) in several
controllable pieces.
Working position
Hold the control handle with your right hand, and the drive
tube with your left hand. Your left arm should be extended
to the most comfortable position.
The shaft should always be held at an angle of 60° or less!
The most convenient working position is a tool angle of
60°, but any lesser angle may be used to suit the situa-
tion concerned.
Cross-cutting
To avoid pinching the bar in the cut, position the cutting
attachment with the hook against the branch and then
perform the cross-cut from the top downwards.
Relieving cut
• To avoid tearing the bark on thick branches, always
start by performing a relieving cut ( 1) on the under-
side of the branch.
• To do this, apply the cutting attachment and pull it in an
arc across the bottom of the branch (see illustration).
• Locate the hook against the branch and then perform
the cross-cut ( 2).
