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 Filler

Oil
Reservoir
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.
