6. Operation
-----------------------------------------------------------------------------------------------------------------------------------------
■STARTING ENGINE
WARNING
The cutting head will start rotating upon the
engine starts.
■Cold start
1. Release the throttle lever and make sure it
is fully back.
2. Set the ignition switch to the “-” position.
3. Push the primer pump several times until
fuel flows out in the clear tube.
4. When the engine is cool, move the choke lever
to the closed position.
5. Place the unit on a flat, firm place. Keep the
cutting head clear of everything around it.
6. While holding the unit firmly, pull out the
starter rope quickly until engine fires.
IMPORTANT
Avoid pulling the rope to its end or returning it
by releasing the knob. Such actions can cause
starter failures.
7. Move the choke lever downward to open the
choke, and restart engine.
8. Allow the engine to warm up for a several
minutes before starting opertion.
■Warm start
1. When restarting the engine immediately after
stopping it, leave the choke open.
2. Overchoking can make the engine hard to start
due to excess fuel. When the engine failed to
start after several attempts, open the choke and
repeat pulling the rope, or remove the spark
plug and dry it.
■STOPPING ENGINE
1. Release the throttle lever and run the engine
for half a minute.
2. Shift the ignition switch to the “STOP”
position.
NOTE
If the engine doesn’t stop after stopping the
switch, close the choke so that engine will stop
after a little.
■Handle adjustment
The handle can be adjusted ± 90° to left and right
side according to the required cut.

1. Pull the unlock button out and hold it in its
position
2. Turn the handle in desired direction to the end.
Make sure the handle engages in position.
•Do not press the throttle during this operation!
■Hedge Trimming Techniques
•Trimmer sides of a hedge first, and then
the top.
•Adjust the handle so that it fits the intended
cut and start the product as described.
•Cut and remove branches exceeding the
cutting capacity (max. 27 mm) of this product
using a proper pruner before operation.
•Move the cutting blade lightly through the
cutting surface in a sweeping motion
following the shape of the hedge or shrub. A
slight tilt downwards of the cutting blade in
the direction of motion is recommended for
optimum cutting performance.
•Do not to rush and do not attempt to cut
too much with one stroke of the cutting blade.
•First cut both sides from the bottom cutting
upwards to the top. This will prevent any of
the cuttings falling into the path of the area
still to be cut
•Cut in a number of stages if the area is
particularly long to achieve a better result;
smaller cuttings will allow for easy
composting.
WARNING
•Always follow the safety precautions.
•The hedge-trimmer must only be used to trim
hedges or small bushes. It is forbidden to cut
other types of material. Do not use the
hedge-trimmer as a lever to lift, move or break
objects, nor lock it on fixed supports.
•It is forbidden to apply tools or applications
that are not the ones indicated by the
manufacturer onto the hedge-trimmer’s power
take-off. Do not use it for pruning trees or
cutting grass.
•Use only as much throttle as is needed to do
the job. Excessive engine speed is unnecessary.
•Avoid cutting thick branches, for which will
damage the blades and shorten the life of drive
systems.
•Tilting the trimmer 5 to 10° to the cutting
object will make the job easy and bring a good
result.
•Always keep your body to the carburetor side
of your trimmer, never on the muffler side.

7. Maintenance
-------------------------------------------------------------------------------------------------------
WARNING
•Make sure that the engine has stopped and is
cool before performing any service to the
machine. Contact with moving cutting head or
hot muffler may result in a personal injury.
■BLADE
•Check the blade and the fasteners for
looseness, cracking, or bending.
•Check the cutting edges and reform with a flat
file.
Point:
1. Keep the end corner sharp.
2. Round the root of the edge.
3. Do not use water when using a grinder.
•You need not to adjust the gap between upper
blade and lower blade as this product is
designed to have optimal gap when it is properly
set up.
■SHARPENING
Always keep the file or sharpener at an angle of
45° to the blade, and:
•Always grind in the direction of the cutting
edge;
•Note: files cut only in one direction; lift the file
from the blade when returning to start a new
pass;
•Remove all burr from the edge of the blade
with a slip stone;
•Remove as little material as possible;
•Before refitting the sharpened blades, remove
filings and then apply grease.
Do not try to sharpen a damaged blade: change
it or take it to a Service dealer.

■SAFETY LOCK
•Stop operation when the safety lock is
defective.
•Safety lock is the device not to accelerate the
throttle lever without intention. While pushing
the safety lock, you can accelerate the throttle
lever.
1. Check if the throttle lever does not move
when you do not push the safety lock.
2. Check if the throttle lever moves when you
grasp or release it while pushing the safety lock.
3. Check if the safety lock returns to its original
position when you release your hand from safety
lock.
•If you find any defects at the checks above,
contact your nearest servicing dealer for repair.
■AIR FILTER
•The air filter, if clogged, will reduce the engine
performance. Check and clean the filter element in
warm, soapy water as required. Dry completely
before installing. If the element is broken or shrunk,
replace with a new one.
■FUEL FILTER
•When the engine runs short of fuel supply, check
the fuel cap and the fuel filter for blockage.
■SPARK PLUG
• Starting failure and mis-firing are often
caused by a fouled spark plug. Periodically clean
the spark plug and check that the spark gap is in
the correct range.
• When you take off the spark plug, twist (1)
and pull off the cap (2).
IMPORTANT
• Note that using any spark plugs other than
those designated may result in the engine failing
to operate properly or in the engine becoming
overheated and damaged.
• To install the spark plug, first turn the plug
until it is finger tight, then tighten it a quarter
turn more with a socket wrench.
TIGHTENING TORQUE: 9.8~11.8 N.m
■GEAR CASE
•Supply multi-purpose grease at every 25 hours of
use.
1. Use a grease pump.
2. Feed grease until it comes out of the base of
blades(a).
■MUFFLER
WARNING
•Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any sign
of exhaust leakage is found, do not use the
brush cutter and have it repaired immediately.
•Note that failing to do so may result in the
engine catching on fire.

8. Storage
