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 bottom of the
branch as far as the bar nose. Perform
the cross-cut (2).
Cutting Above Obstacles:
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 de-
pends 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. Tool angle in this case
depends on the position of the branch.
Using the Pole Pruner
This machine is designed especially for
cutting branches.
Never use this machine for any other
purpose. Never try to cut stones, metals,
plastics, or any other hard objects.
Using for purposes other than cutting
branches may damage the machine or
cause serious injury.
Preparations
Wear suitable protective clothing
■
and equipment – see section “Safety
Precautions”.
Choose the best work position for
■
safety against falling objects such as
branches.
Start the engine.
■
Put on the strap.
■
Never stand directly underneath the
branch you are cutting – be aware of
falling branches. Note that a branch
may spring back at you after it hits the
ground.
Cutting Sequence:
To allow branches to fall freely, always
cut the bottom branches first. Prune
heavy branches (large in 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 comfortable position.
The shaft should always be held at
an angle of 60° or less.
Standard Cut:
The most convenient working position is
a tool angle of 60°, but any other angle
may be used to suit the situation.
Adjust the pump as follows:
1. Stop the engine and make sure the stop switch is in the OFF position.
2. Place the unit on its side with the oil reservoir (D) up.
3. Using a screwdriver, turn the oil flow rate adjustment screw (E) in the desired direction:
• clockwise–decrease lubrication.
• counter clockwise–increase
lubrication.
NOTE:
The automatic oiler is preset to deliver a sufficient oil discharge volume during normal
operating conditions. During heavy or dry cutting conditions, the oil discharge volume
may be increased to assure adequate lubrication. If oil is leaking from the bar cover
area, reduce the oil discharge volume. Refill the oil reservoir with each tank of fuel.
NOTE:
Very little visible oil on the saw chain will provide sufficient lubrication.
