To avoid the chance of serious injury or
death, follow these safety precautions
during operation:
Keep bystanders at least 50 feet (15 meters) away
from the operating pruner to reduce the risk of
being cut by moving saw chain or struck by falling
objects or thrown debris.
Always wear a hard hat
to reduce the risk of head
injuries during operation of
this machine.
Never operate the pruner at
an angle greater than 60°
in order to reduce the risk of
being struck by falling objects
during operation.
Wear nonslip heavy-duty
work gloves to improve
your grip on the pole
pruner handle. Wear
snug-fitting clothes that
also permit freedom
of movement. NEVER
wear shorts!
Always operate with both
hands firmly gripping the
machine.
Wear sturdy footwear
with nonslip soles to provide
good footing. Steel-toed safety
boots are recommended. Never
operate this product barefoot.
Keep a proper footing and
do not overreach—maintain your balance at all
times during operation.
Kickback and Pinching Safety Precautions
WARNING!
Both kickback and pinching may
cause you to lose control of the pole
pruner tool which could result in
serious personal injury. Do not rely
exclusively on the safety device
built into the pruner! You must take
several steps to keep your jobs free
from accident or injury:
1. Understand kickback and pinching! You can reduce or eliminate
the element of surprise. Sudden
surprises contributes to accidents.
Beware of Kickback!
Kickback can occur whenever the tip of the guide bar
touches an object while the
saw is operating. Kickback may force the
bar up and back toward the operator with
lightning-like speed!
4
2. Keep a firm grip on the pole pruner
with both hands whenever the engine is running. A firm grip will help
you reduce the affects of kickback
and pinching as well as maintain
control
of the machine.
3. Make sure the area in which you
are cutting is free from obstructions. Do not let the nose of the
guide bar contact a log, branch, or
any other obstructions which could
be hit while you operate the pole
pruner tool.
4. Cut at high engine speeds.
5. Follow the manufacturer’s instructions for sharpening and maintaining the chain.
6. Use only the replacement bar and
chain or equivalent as specified by
the manufacturer.
Beware of pinching.
Pinching the saw along the
tip of the guide bar may force
the bar back rapidly toward
the operator. Pinching can
occur whenever wood closes in around the
moving chain.

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.
Cutting On A Work Platform:
Standard Cut:
The most convenient working position is
a tool angle of 60°, but any other angle
may be used to suit the situation.
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 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
Relieving Cut:
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:
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 depends on the position of the branch.
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.
Flush-cutting Thick Branches:
If branch diameter is more than 10 cm, first perform undercut (3) and cross-cut at a
distance (A) of about 25 cm from the final cut. Then carry-out the flush-cut (4), starting with a relieving cut and finishing with a cross-cut.
14
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).

Sharpening the Chain
■■ When the cutting edges of the blade become dull, they can be re-sharpened
with a few strokes of a file.
■■ In order to keep the blade in balance, all cutting edges must be sharpened
equally.
■■ In addition, inspect the chain for correct adjustment (more frequently with a
new chain). The chain should feel snug but still pull freely. Refer to adjustment
procedures.
CAUTION!
Keep the chain sharp and properly adjusted.
30°
WARNING!
The saw chain is very sharp. Wear gloves to protect your hands when working with or around the saw chain.
Sharpening Instructions
IMPORTANT!
File all the cutters to the same angle and depth! Unequal filing may cause the
saw to vibrate or cut erratically!
1. Using a 4.5 mm round file, sharpen all cutters to a 30° angle. Make sure that one
fifth (20%) of the file’s diameter is always held above the cutter’s top plate.
2. After all cutters are sharpened, use
a depth gauge joiner (A) to measure the height of each depth gauge.
90°
3. As required, lower the depth gauges to a height of 0.025 inch. Use a flat file.
4. After all depth gauges have been adjusted, use a flat file to round each depth
gauge leading edge to its original curvature and angle.

NOTE:
For consistent filing angles, use a filing guide.
