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 pinch-
ing! You can reduce or eliminate
the element of surprise. Sudden
surprises contributes to accidents.
Kickback and Pinching Safety Precautions
2. Keep a rm grip on the pole pruner
with both hands whenever the en-
gine is running. A rm 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 obstruc-
tions. 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 instruc-
tions for sharpening and maintain-
ing the chain.
6. Use only the replacement bar and
chain or equivalent as specied 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.
Beware of Kickback!
Kickback can occur when-
ever 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!

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.

lubrication.
NOTE:
The automatic oiler is preset to deliver a sufcient 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. Rell the oil reservoir with each tank of fuel.
NOTE:
Very little visible oil on the saw chain will provide sufcient lubrication.

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), start-
ing with a relieving cut and finishing with a cross-cut.

WARNING!
Before performing any maintenance,
repair, or cleaning work on the unit,
make sure the engine and cutting
attachment are completely stopped.
Disconnect the spark plug wire
before performing service or mainte-
nance work.
IMPORTANT!
For detailed maintenance information
about your T230/231, AH230/231, or
PB230, consult the owner's manual that
was provided with it. If it has been lost
or misplaced, contact Shindaiwa for a
replacement.
Maintenance
WARNING!
Non-standard parts may not oper-
ate properly with your unit and may
cause damage and lead to personal
injury.
IMPORTANT!
Using non-standard replacement parts
could invalidate your Shindaiwa war-
ranty.
Prior to each work day, perform the follow-
ing:
Clean any debris or dirt from the
cutting attachment. Check the bar
and chain for damage or incorrect
adjustment.
Daily Maintenance
WARNING!
The saw chain is very sharp. Wear
gloves to protect your hands when
working with or around the saw
chain.
Check for loose or missing screws or
components. Make sure the cutting
attachment is clean, free of debris and
securely fastened.
Check the entire machine for leaking
fuel or grease.
Make sure that nuts, bolts, and
screws (except carburetor adjusting
screws) are tight.
15-hour Maintenance
Every 15 hours of operation
(more frequently in dusty or dirty
conditions):
Remove the sprocket cover and
inspect the sprocket (A) for excessive
dirt, debris, or wear. Remove the
guide bar and clean out the guide bar
groove. If the sprocket is excessively
worn, replace it with a new one.

Lubricate the gearcase. To perform this operation, first remove the gearcase
from the upper outer tube as follows.
CAUTION!
Do not remove the D-shaped shim washer from the gearcase clamp! The shim
washer prevents damage from overtightening the tube clamp screw.
■loosen the gearcase clamp bolt (B).
■remove the index bolt (C) from the gearcase.
■slide the gearcase out of the tube.

50-hour Maintenance
Every 50 hours of operation (more frequently in dusty or dirty
conditions):
■Using a lever-type grease gun, pump lithium-base grease (about 10 grams)
into the grease fitting (D) until you see old grease being purged from
the gearcase, which can be seen in the outer tube cavity. Clean up excess
grease, then reassemble the gearcase onto the outer tube.
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.
WARNING!
The saw chain is very sharp. Wear gloves to protect your hands when work-
ing with or around the saw chain.

Sharpening Instructions
IMPORTANT!
File all the cutters to the same angle and depth! Unequal ling 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.
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 ling angles, use a ling guide.
NOTE:
See specication page for replacement bar and chain specs.
