Pruning techniques

Pruning operation
Preparations
 Check unit for loose/missing nuts, bolts and screws. Tight-
en and/or replace as needed.
 Choose the best work position for safety against the falling
object (Branch etc)
 Start the unit.
 Put on the strap.
Never stand underneath the branch you are cutting–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 branches first.
Prune heavy branches (large diameter) in several controllable
pieces.
Working Position
Hold the control handle with your right hand, and the shaft with
your left hand. Your left arm should be extended to the most com-
fortable position.
The shaft should always be held at an angle of 60° or less.
Typical applications
Standard cut(A):
The most convenient working position is a tool angel of 60°, but
any other angle may be used to suit the situation concerned.
Cutting above obstacles(B):
Thanks to the unit's long reach it is possible to prune branches
that are overhanging obstacles, such as rivers or lakes. The tool
angle in this case depends on the position of the branch.
Cutting on a work platform:
The unit's long reach enables cutting to be performed next to the
trunk without the risk of the work platform damaging other
branches. The tool angle in this case depends on the position of
the branch.
Working techniques
Relieving cut:
To avoid tearing the bark, kickback or pinching the bar when
pruning thick branches, always start by performing a relieving cut
(1) on the underside of the branch.
To do this, apply the cutting attachment and pull it across the bot-
tom of the branch as far as the bar nose. Perform the cross-cut
(2).
