Both kickback and pinching may
cause you to lose control of the pole
pruner which could result in serious
personal injury. Do not rely exclu-
sively 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 surprise
contributes to accidents.
2. Keep a firm grip on the pole
pruner with both hands when-
ever the engine is running. A
firm grip will help you reduce
the effects of kickback and
Kickback and Pinching Safety Precautions
pinching as well as maintain-
ing control of the unit.
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.
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.

Never operate power
equipment of any kind
if you are tired or if you
are under the influence
of alcohol, drugs,
medication, or any other
substance that could affect
your ability or judgement.
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!
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.
Read and follow this
operators manual.
Failure to do so could
result in serious injury.
Always wear a hard hat
to reduce the risk of head
injuries during operation
of this unit. Wear eye
and hearing protection
at all times during the
operation of this unit.

Operating Precautions
■Make sure the chain and
sprocket are correctly adjusted
before operating the pruner
(see page 15 for adjustment
procedures). Never attempt
chain adjustment with the
engine running!
■Always make sure the cutting
attachment is properly
installed and firmly tightened
before operation.
■Never use a cracked or
warped guide bar: replace it
with a serviceable guide bar
and make sure it fits properly.
■If a saw blade should bind fast
in a cut, shut off the engine
immediately. Push the branch
or tree to ease the bind and
free the blade.
■Make sure there are no missing
or loose fasteners, and that the
ignition switch and throttle
controls are working properly.
■Before starting the engine,
make sure the saw chain is
not contacting anything.
■Make sure there is always
good ventilation when operat-
ing the pruner. Fumes from
engine exhaust can cause
serious injury or death. Never
run the engine indoors!
■Do not operate the pole pruner
with the muffler 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 in-
stalled parts or attachments.
■Never transport the pruner
nor set it down with the
engine running. An engine
that’s running could be
accidentally accelerated
causing the chain to rotate.

Filling The Oil Reservoir
Adjusting Oil Flow Rate
CAUTION!
The oil flow adjusting screw must
be pressed in slightly in order to
turn. Failure to do so could
damage the pump and screw.
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.
1. Place the pole pruner on a clean,
flat surface with the oil filler cap
facing up. See Figure 20. Wipe off
any debris from the oil cap and
from around the oil filler neck.
2. Remove the oil filler cap and fill the
reservoir with bar and chain oil,
then replace the cap.
3. Wipe up spilled oil from the unit
before restarting the pole pruner.
The guide bar and chain are lubri-
cated 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:
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 up. See Figure 21.
3. With a screwdriver, push in on the
oil flow rate adjusting screw and
turn in the desired direction (there
are three incremental settings):
• clockwise–decrease lubrication.
• counter clockwise–increase
lubrication.
OPERATION
P230_OM_62887-94011_01EC 8/18/05, 15:3217

are damaged.
■Never smoke or light any fires
near the unit or fuel!
■Never place any flammable
material near the engine
muffler!
■Never operate the engine
without the muffler and spark
arrester in place and properly
functioning!
Mixing Fuel
CAUTION!
This engine is designed to operate
on a 50:1 mixture consisting of
unleaded gasoline and a premium
2-cycle mixing oil only. Use of
Non-approved mixing oils can lead
to excessive maintenance costs
and/or engine damage.
CAUTION!
Some gasolines contain alcohol as
an oxygenate. Oxygenated fuels
may cause increased operating
temperatures. Under certain
conditions, alcohol-based fuels
may also reduce the lubricating
qualities of some mixing oils.
Never use any fuel containing
more than 10% alcohol by volume!
Generic oils and some outboard
motor oils may not be intended for
use in high-performance air-cooled
2-cycle engines, and should never
be used in your Shindaiwa engine.
■Use only fresh, clean unleaded
gasoline with a pump octane rating
of 87 or higher.
■Mix gasoline with 50:1 Shindaiwa
Premium 2-cycle mixing oil or with
an equivalent high quality 2-cycle
mixing oil.
Examples of 50:1 mixing quantities
■ 1 gallon of gasoline to 2.6 oz. mixing oil
■ 5 litres of gasoline to 100 ml. mixing oil
IMPORTANT!
Mix only enough fuel for your immedi-
ate needs! If fuel must be stored
longer than 30 days and Sindaiwa
One oil with fuel stabilizer is not
used, it should first be treated with a
fuel stabilizer such as StaBil™.

Starting the Engine
4. While holding the outer tube firmly
with one hand, slowly pull the
recoil starter handle until resis-
tance is felt, then pull quickly to
start the engine.
1. Slide the ignition switch to the “I”
position (engine ON).
2. Press the primer bulb until fuel can
be seen flowing in the transparent
return tube.
3. Set the choke lever to the CLOSED
position if engine is cold.
Make sure the
cutting head
is clear of
obstructions!
Primer Bulb
Return Tube
IMPORTANT!
Engine ignition is controled by a two position switch mounted on the throttle
housing labeled, "I" for ON or START and "O" for OFF or STOP.

Figure 23 Figure 25
IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not flood
the engine with fuel.
CAUTION!
Do not pull the recoil starter to the
end of the rope travel. Pulling the
recoil starter to the end of the rope
travel can damage the starter.

Starting the Engine (continued)
WARNING!
Never start the engine from the
operating position.
WARNING!
The chain may rotate when the
engine is started!
When the Engine Starts...
■After the engine starts, allow the
engine to warm up at idle 2 or 3
minutes before operating the unit.
■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 the next page).
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded
with fuel. If flooding is suspected,
move the choke lever to the open
position and repeatedly pull the recoil
starter to remove excess fuel and start
the engine. If the engine still fails to
start, refer to the troubleshooting
section of this manual.
5. When the engine starts, slowly
move the choke lever to the
"OPEN" position. See Figure 26.
(If the engine stops after the initial
start, close the choke and restart.)
