ensuring that the cutter section of the saw chain is
facing the front.
2. Engage the saw chain into the sprocket.
3. Insert the groove of the guide bar into the pruner’s
main unit and adjust the regulating screw to ensure
that the adjuster is inserted in the circular hole of the
guide bar.
4. Put the chain cover on and temporarily screw it in
place using a nut, to the extent that the guide bar can
be moved.
5. Lift up the leading edge of the guide bar and using a
screw driver turn the regulating screw clockwise to
tighten the saw chain until the saw chain slightly
touches the lower side of the guide bar.
6. Securely tighten the nut on the chain cover, using the
box spanner, provided as an accessory with the
product.
7. Verify that the saw chain on the central section of the
guide bar can be lifted by the fingers 3 to 4 mm off

gloves when handling the guide bar and
saw chain.
• Maintain the tension of the saw chain
properly at all times.
• If not enough tension is applied to the
saw chain it can easily be dislodged
when the saw chain is in motion.
• If too much tension is applied to the
guide bar, saw chain and clutch may
wear prematurely as a result.

DANGER
• Ensure that the guide bar and saw chain
are installed on the pruner before
verifying the discharging rate of the
chain oil. The rotator will be exposed
and therefore dangerous if the guide bar
and the saw chain are not installed on
the pruner.
Before operation
Chain oil
1) Adding oil
1. Remove the oil tank cap and pour the chain oil
(SAE #10W-30) into the oil tank.
2. Once the oil has been poured into the oil tank,
tighten the oil tank cap to securely close the tank.

−US-15 −
CAUTION
• It may take some time before the oil
begins to discharge once the oil has
been added to a new product or when oil
has been added to an empty tank. Do
not turn the pruner on at a high speed
in such circumstances.
• When a new chain is to be used,
immerse the chain in chain oil for some
time prior to installing it on the pruner,
or pour the oil directly on to the chain
and the guide bar, after installing it on
the pruner. If they are not properly lubri-
cated with oil the pruner may seize.
The regulating screw has three positions, Minimum,
Intermediate and Maximum, only.
The regulating screw is set to Intermediate at the time
of shipping. It is recommended that the product be used
with this setting for ordinary use.
• Increase the discharging rate when cutting hard
branches or branches with a lot of resin (pitch),
or when the viscosity of the oil is high during
winter.
1. Insert a minus screw driver into the regulating
screw at the bottom of the main unit.
2. When applying pressure with the minus screw
driver, turn the screw to the right (clockwise) to
reduce the discharging rate and to the left
(counterclockwise) to increase the discharging
rate.
3. Turn the engine on and turn the saw chain, with
the guide bar facing the ground or tree. Oil will
attach to the ground or tree, if the oil is
discharging.
CAUTION
• Using the pruner with a saw chain too loose
may result in the saw chain becoming
dislodged and could cause an accident.
Please be sure to check the tension of
the saw chain before starting any work.

Mixing Gasoline And Oil
1. Always mix fuel and oil in a clean container
approved for gasoline.
IMPORTANT: The engine used on this Pruner is of
a
2-cycle design. The internal moving parts of the
engine, i.e., crankshaft bearings, piston pin bearings
and piston to cylinder wall contact surfaces, require
oil mixed with the gasoline for lubrication.
2. Mark the container to identify it as fuel mix for
the Pruner.
3. Use regular unleaded gasoline and fill the container
with half the required amount of gasoline.
Failure to add oil to the gasoline or failure to mix oil
with the gasoline at the appropriate ratio will cause
major engine damage which will void your warranty.
4. Pour the correct amount of oil into the container
then add the remaining amount of gasoline.

The fuel: oil ratiois 50 parts gasoline to 1 part oil or 50:1. 8. Always use a spout or funnel when fueling to
reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 inch (6 mm-13
mm) from the top of the tank. Avoid filling to the
top of the tank filler neck.
Note: Never use a mixing ratio less than 50:1
regardless of the oil package mixing
instructions. Ratios less than 50:1,
(for example, 60:1,80:1, 100:1),reduce
the amount of lubrication to the internal
moving parts of the engine and can cause
damage.

position, then pull the starter grip.
Before Starting The Engine
1. Fill the fuel tank as instructed in the Before Operation
section of this manual (page US-14).
2. Rest the Pruner on the ground.
3. Make sure the cutting attachment is clear of any
broken glass, nails, wire, rocks or other debris.
4. Keep all bystanders, children and animals away
from the working area.
Cold Starting Procedure
This Pruner is equipped with a fuel primer and a
choke system.To start a “cold” engine properly, perform
the following procedure:
1. Pump the primer bulb at the bottom ofthe carbu-
retor untilfuel can be seen flowing throughthe
fuel return line to the fuel tank.
(Flowing fuel should be almost clear, not foamy or
full ofbubbles.)

choke lever to the open (
) position:
A. Go aheadand open the choke.
B. Make sure the throttle trigger is set to the idle
position.
C. Pull the starter grip until the engine starts.
Hot Restart
To start an engine that is already warmed up (hot
restart), or if the ambient temperature exceeds 68°F
(20°C):
1. Pump the primer bulb at the bottom of the car-
buretor until fuel can be seen flowing through the
fuel return line to the fuel tank.
2. Move the choke leverto the open (
)position
and move the stop switchto the “ON” position.
3. Leave the throttle trigger inthe idle position and
pull the starter grip.

Operation
DANGER
• Do not stand immediately below the
branch that is to be cut. The branch may
fall directly below and the branch may
also bounce off other branches or the
ground in an unexpected direction and
cause injury to the worker.
• Do not allow anyone to enter within a 15
meter radius.
• The Pruner is not insulated to prevent
electric shock. Keep it away from any
power lines with at least 15 meters when
working, as there is threat of
electrocution.
Working position
1. Choose a working position where the inclination of
the pole remains at 60 degrees or less.
2. Start cutting from the lower branches first so that the
branches will fall off easily when cut.
3. The cut branches may fall towards the worker, so be
sure to select a location that enables a stable footing
and provides an easy escape in the case of an
emergency.
WARNING
• Wear a hat or helmet, protective glasses,
gloves and ear plugs while working.
Furthermore, wear a dust mask
whenever a lot of pollen or chipping
powder is expected, which may be
harmful for the health.
Cutting wood
1. Turn the pruner on full throttle and press the saw
chain lightly against the wood to cut.
2. The cutting capacity is reduced when the engine
revolution is slowed down and the saw chain is
pressed hard against the wood.
IMPORTANT
• Pressing the saw chain hard against the wood not
only tires the operator quicker but also quickens
the wear of the saw chain and guide bar.
• If wood cannot be cut without pressing the saw
chain hard against it, this indicates that the saw
chain is becoming dull. In such cases, either
sharpen the saw chain or replace it with a new
chain.
Pruning thick branches
Attempting to cut a thick branch in one go often results
in the guide bar jamming in the branch or otherwise
encountering difficulties in cutting. The method
described below makes cutting thick branches easier:
1. First of all, cut a section slightly away and on the
lower side of the desired area of the branch to be cut.
2. Then, start cutting from the upper side of the branch.
3. Thereafter, cut into
the lower side
where the desired
area of branch is to
be cut.
4. Finally, cut through
from the upper side
where the branch is
to be cut, cutting
the branch off.
