Sprocket Cover Nut

Adjusting the Chain

Place the pole pruner on a clean, flat sur-

face. (For readjustment during operation,

shut down the engine, then allow the guide

bar and chain to cool before proceeding

with the adjustment procedure).
Loosen the sprocket cover nut with a

plug wrench.

1.

2.

Pull the chain by hand along the top

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

securely while lifting the tip of the

guide bar.

4.

5.

Inspect the chain for correct adjust-

ment (more frequently with a new

chain). The chain should feel snug but

still pull freely.

6.

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.

WARNING!
The saw chain is very sharp.

Wear gloves to protect your hands
when handling.

WARNING!
Never attempt to install,

replace, or adjust the chain with the
engine running.

Oil Flow Adjusting Screw

Filling the Oil Reservoir

CAUTION!
An increase in bar oil flow rate will
speed oil consumption, requiring more
frequent checks on the oil reservoir. To

ensure sufficient lubrication, it may be
necessary to check the oil level more

frequently than at fuel tank refills.

NOTE:

The oil reservoir has a capacity sufficient
to provide about 40 minutes of cutting
time (when set to deliver the minimum

flow rate, or about as long as you’ll get
from a tank of fuel).

WARNING!
Never fill 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.

Place the pole pruner on a clean, flat

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

reservoir with bar and chain oil, then

replace the cap.

1.

2.

Wipe up spilled oil from the unit before

restarting the pole pruner.

3.

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.

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.

1.

2.

Using a screwdriver, turn the oil flow

rate adjustment screw in the desired

direction.

Clockwise to decrease lubrication.
Counter-clockwise to increase

lubrication.

Chain Tensioning

Screw

Lift the nose of the guide bar while

turning the chain tensioning screw:

Clockwise to tighten the chain.

Counter-clockwise to loosen the chain.
