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 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!

Safety Precautions

DANGER!

THE PRUNER IS NOT

INSULATED AGAINST

ELECTRICAL SHOCK!

Approaching or contacting electrical line with the pruner could cause death or serious injury. Keep the pruner at least 10 meters away from electrical lines or branches that contact electrical lines.

A pole pruner operates at very high speeds and has the potential to do serious damage if misused, abused or mishandled. To reduce the risk of injury, you must maintain control at all times, and observe all safety precautions during operation. Never permit a person without training or instruction to operate this pruner!

WARNING!

Kickback and Pinching

Both kickback and pinching may cause you to lose control of the pole pruner 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:

Understand kickback and pinching!

■

You can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

■

Cut at high engine speeds.

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!

Keep a rm grip on the pole pruner

■

with both hands whenever the engine

is running. A rm grip will help you

reduce the effects of kickback and pinching as well as maintaining control of the unit.

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.

Follow the manufacturer’s instructions

■

for sharpening and maintaining the chain.

■

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.

The Properly Equipped Operator

Always wear a hard hat to

reduce the risk of head injuries during operation of this unit.

Wear nonslip heavy-duty work gloves to improve your grip on the pole pruner handle. Wear snug-tting clothes that also permit freedom of movement.

Operate the saw only in a well

■

ventilated area. Be aware of carbon monoxide poisoning. Exhaust gases and lubrication oil mist can cause serious injury or death.

Do not operate the unit with the mufer

■

removed. When cutting a limb that is under

■

tension, be alert for springback so that you will not be struck by the moving limb.

Always stop the engine immediately and

■

check for damage if you strike a foreign object or if the unit becomes tangled. Do not operate with broken or damaged equipment.

Stop the unit immediately if it suddenly

■

begins to vibrate or shake. Inspect for broken, missing or improperly installed parts or attachments.

Never transport the unit nor set it down

■

with the engine running. An engine that’s running could be accidentally accelerated causing the chain to rotate.

Make sure the chain cover is in place

■

when transporting and storing the pruner.

When carrying by hand, the chain

■

should be pointing backward.

Operating Precautions (continued)

Always maintain the P231 pole

■

pruner according to the this owner’s manual and follow the recommended scheduled maintenance.

2. plug wrench.

Pull the chain by hand along the top

4. of the guide bar several times from the engine to the bar’s tip. The chain should feel snug but still pull freely.

Tighten the sprocket cover nut

5. securely while lifting the tip of the guide bar.

CAUTION!

A loose chain can jump off the guide bar causing damage to the chain and associated equipment. Always make sure the chain is properly adjusted; check more often when you are breaking in a new chain.

IMPORTANT!

Proper chain adjustment is essential for maximum performance, long chain life, and operator safety. Always inspect chain tension before operating the pole pruner.

Chain Oiler

WARNING!

Never ll the oil reservoir nor

adjust the oiler with the engine running.

IMPORTANT!

The service life of the chain and guide bar is affected by the quality of the lubricant. Using superior lubricant such as Shindaiwa Bar and Chain Oil will help ensure a long service life, For cold weather operation, mix bar and chain oil with an equal part of kerosene.

Filling the Oil Reservoir

NOTE:

The oil reservoir has a capacity sufcient

to provide about 40 minutes of cutting time (when set to deliver the minimum

ow rate, or about as long as you’ll get

from a tank of fuel).

Place the pole pruner on a clean, ﬂat

1. surface with the oil ﬁller cap facing up. Wipe off any debris from the oil cap and from around the oil ﬁller neck.

Remove the oil ﬁller cap and ﬁll the

2. reservoir with bar and chain oil, then replace the cap.

Adjusting Oil Flow Rate

CAUTION!

An increase in bar oil ow rate will

speed oil consumption, requiring more frequent checks on the oil reservoir. To

ensure sufcient lubrication, it may be

necessary to check the oil level more

frequently than at fuel tank rells.

The guide bar and chain are lubricated automatically by a pump that operates whenever the chain rotates. The pump is set at the factory to deliver a minimum ﬂow rate, but it can be adjusted in the ﬁeld. A temporary increase in oil ﬂow is often desirable when cutting materials such as hardwood or wood with a lot of pitch.

Inspect the chain for correct adjust-

6. ment (more frequently with a new chain). The chain should feel snug but still pull freely.

Adjust the pump as follows:

Stop the engine and make sure the stop

switch is in the OFF position. Place the unit on its side with the oil

reservoir up.

After the engine starts, allow the

■

engine to warm up at idle 2 or 3 minutes before operating the unit.

After the engine is warm, pick up the

■

unit and clip on the shoulder strap if so equipped.

Advancing the throttle makes the

■

cutting attachment turn faster; releasing the throttle permits the attachment to stop turning. If the cutting attachment continues to rotate when the engine returns to idle, carburetor idle speed should be adjusted (see “Adjusting The Engine Idle” on the next page).

Stopping the Engine

WARNING!

The cutter attachment can continue moving after the engine is stopped!

Adjusting the Engine Idle

Cool the engine by allowing it to idle

1. for two or three minutes.

Slide the ignition switch to the “O” or

2. STOP position.

OFF

WARNING!

The cutter attachment must never rotate at engine idle speed. If the idle speed cannot be adjusted by the procedures described here, return the pruner to your Shindaiwa dealer for inspection.

NOTE:

The mixture of the carburetor on this unit cannot be adjusted.

The engine must return to idle speed whenever the throttle trigger is released. Idle speed is adjustable and must be set low enough to permit the engine clutch to disengage the cutter attachment when throttle trigger is released.

Check and Adjust Idle Speed

Start the engine and allow it to idle two

1. or three minutes, or until it warms up.

If the cutter attachment rotates at

2. engine idle, reduce idle speed by turning the idle adjusting screw counterclockwise as necessary.

If the engine is stalling and won’t idle,

3. increase idle speed by turning the idle adjustment screw clockwise.

IMPORTANT!

Use a tachometer, if one is available, to set engine idle. Standard idle speed is: 2,750 (±250) min-1.

Idle Adjusting Screw

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.

Standard Cut:

The most convenient working position is a tool angle of 60°, but any other angle may be used to suit the situation.

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.

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 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.

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.

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.

Maintenance (cont.)

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 the section on “Adjusting the Chain” for adjustment procedures.

IMPORTANT!

File all cutters to the same angle and depth! Unequal ﬁling may cause the saw to vibrate or cut erratically!

Using a 4.5 mm round ﬁle, sharpen all

1. cutters to a 30° angle.

NOTE:

For consistent ling angles, use a ling

guide

After all cutters are sharpened, use

2. a depth gauge joiner to measure the height of each depth gauge.

As required, lower the depth gauges to

3. a height of 0.6 mm.

After all depth gauges have been

4. adjusted, use a ﬂat ﬁle to round each depth gauge leading edge to its original curvature and angle.
