•Exhaust emission are controlled by the funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with-
out addition of any major hardware or the introduc-
tion of an inert material during combustion.
• These engines are certified to operate on unleaded
gasoline.
• If you use a gasoline of a lower octane value than pre-
scribed, there is a danger that the engine tempera-
ture may rise and an engine problem such as piston
seizing may consequently occur.
• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health and
the environment.
• Poor quality gasolines or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
■ HOW TO MIX FUEL
WARNING
•Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be
mixed.
2. Put some of the gasoline into a clean, approved fuel
container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for at
least one minute. As some oils may be difficult to
agitate depending on oil ingredients, sufficient agi-
tation is necessary for the engine to last long. Be
careful that, if the agitation is insufficient, there is an
increased danger of early piston seizing due to ab-
normally lean mixture.
5.
Put a clear indication on the outside of the container
to avoid mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy
identification.
■ FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a
dustless place.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.
WARNING
1. Select flat and bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the fu-
eling point before starting the engine.
3. Stop the engine before refueling the unit. At that
time, be sure to sufficiently agitate the mixed gaso-
line in the container.
■ FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause
severe damage to the internal engine parts very quickly.
4. OIL FOR 4-CYCLE ENGINE USE – It can cause spark
plug fouling, exhaust port blocking, or piston ring stick-
ing.
5. Mixed fuels which have been left unused for a pe-
riod of one month or more may clog the carburetor
and result in the engine failing to operate properly.
6. In the case of storing the product for a long period of
time, clean the fuel tank after rendering it empty. Next,
activate the engine and empty the carburetor of the
composite fuel.
7. In the case of scrapping the used mixed oil container,
scrap it only at an authorized repository site.

CUTTING WORK (LINE HEAD USAGE)
WARNING
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting head.
Rocks or other debris could be thrown into eyes
and face and cause serious personal injury.
2. Keep the cutting attachment guard in place at all
times when the unit is operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line does cut-
ting. You will achieve better results by not crowding
the line into the cutting area. Allow the unit to trim at
its own pace.
1. Hold the unit so the head is off the ground and is tilted
about 20 degrees toward the sweep direction.
2. You can avoid thrown debris by sweeping from your
left to the right.
3. Use a slow, deliberate action to cut heavy growth.
The rate of cutting motion will depend on the material
being cut. Heavy growth will require slower action than
will light growth.
4. Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
5. Try to control the cutting motion with the hip rather
than placing the full workload on the arm and hands.
6. Take precautions to avoid wire, grass and dead, dry,
long-stem weeds from wrapping around the head
shaft. Such materials can stall the head and cause
the clutch to slip, resulting in damage to the clutch
system if repeated frequently.
ADJUSTING THE LINE LENGTH
•Your brush cutters are equipped with a semi- auto
type nylon line head that allows the operator to ad-
vance the line without stopping the engine. When the
line becomes short, lightly tap the head on the ground
while running the engine at full throttle.
• Each time the head is bumped, the line advances
about 1 inch (25.4 mm). For better effect, tap the head
on bear ground or hard soil. Avoid bumping in thick,

CUTTING METHOD
a) Use the front left side cutting.
b) Guide the blade from your right to left with it tilted
slightly to your left.
c) When mowing a wide area, start working from your
left end to avoid interference of cut grass.
d) The blade may be seized by weeds if the engine
speed is too low, or the blade cuts too deep into
weeds. Adjust the engine speed and cutting depth
according to the condition of object.
WARNING
•If the grass or other object gets caught in the blade,
or if the unit starts to shake or vibrate, turn off the
engine and check the whole unit. Change the blade
if it has been damaged.
•Turn off the engine and make sure the blade has
completely stopped before checking the blade, and
removing any object got caught in.
OPERATION
1. Check the bolt to fasten the blade and be sure the
bolt has no fault, and no abrasion.
2. Be sure that the blade and the holder have been fas-
tened according to instruction and that the blade turns
smoothly without abnormal noise.
WARNING
•The rotating parts fastened incorrectly may cause
serious accident to the operator.
•Make sure that the blade is not bent, warped,
cracked, broken or damaged.
•If you find any error to the blade, discard it and
By using the shoulder strap, hang the unit on your right
side. Adjust the strap length so that the cutting head
may become parallel to the ground.

WARNING
Make sure to use shoulder strap and cutting attach-
ment guard. If not, it is very dangerous when you slip
or lose your balance.
WARNING
CONTROLLING BLADE BOUNCE
Blade thrust can cause serious personal injury. Care-
fully study this section. It is important that you un-
derstand what causes blade thrust, how you can re-
duce the chance of blade thrust and how you can
remain in control of the unit if blade thrust does oc-
cur.
1. What causes blade thrust:
• blade thrust can occur when the moving blade
contacts an object that it cannot cut. This contact
causes the blade to stop for an instant and then
suddenly move or “bounce” away from the object
that was hit. The operator can lose control of the
unit and the blade can cause serious personal
injury to the operator or any person nearby if the
blade contacts any part of the body.
2. How you can reduce the chance of blade thrust:
a. Recognize that blade thrust can happen. By un-
derstanding and knowing about bounce, you can
help eliminate the element of surprise.
b. Cut fibrous weeds and grass only. Do not let the
blade contact materials it cannot cut such as hard,
woody vines and bushes or rocks, fences, metal,
etc.
c. Be extra prepared for bounce if you must cut where
you cannot see the blade making contact such as
in areas of dense growth.
d. Keep the blade sharp. A dull blade increases the
chance of bounce.
e. Avoid feeding the blade too rapidly. The blade can
bounce away from material being cut if the blade
is fed faster than its cutting capability.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material that
has been cut and other debris.
3. How you can maintain the best control:
a. Keep a good, firm grip on the unit with both hands.
A firm grip can help neutralize bounce. Keep your
right and left hands completely around the respec-
tive handles.
b. Keep both feet spread apart in a comfortable
stance and yet braced for the possibility that the
unit could bounce. Do not overreach. Keep firm
footing and balance.
TRANSPORTING THE UNIT
• When you finish cutting in one location and wish to
continue work in another spot, turn off the engine, lift
up the unit and carry it, paying attention to the blade.
• Never forget to place the protective cover over the
blades.
• When transporting the unit over long distances, de-
tach the blade and fasten the unit by ropes.

WARNING
•Make sure that the engine has stopped and is cool
before performing any service to the machine. Con-
tact with moving cutting head or hot muffler may
result in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine perfor-
mance. Check and clean the filter element in warm,
soapy water as required. Dry completely before in-
stalling. If the element is broken or shrunk, replace
with a new one.

SPARK PLUG
•Starting failure and misfiring are often caused by a
fouled spark plug. Clean the spark plug and check
that the plug gap is in the correct range. For a re-
IMPORTANT
•Note that using any spark plug other than those des-
ignated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and dam-
aged.
•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.

WARNING
•Inspect periodically, the muffler for loose fasten-
ers, any damage or corrosion. If any sign of ex-
haust leakage is found, stop using the machine
and have it repaired immediately.
•Note that failing to do so may result in the engine
catching on fire.

PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into the vent,
and wipe away any carbon buildup. Wipe away any
carbon buildup on the muffler exhaust vent and cylin-
der exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its way
in between the clutch lining and drum, and if it has,
wipe it away using oil-free, lead-free gasoline.

REFILLING TRIMMING LINE
1. For replacement line, use a diameter of 2.4mm(.095in).
The spool is capable for a line upto 6m(20ft) on the
10cm(4”) head. Avoid using a larger line as it may cut
down the trimming performance.
WARNING
• For safety reasons, do not use metalreinforced line.
2. Pinch the slotted area on the both sides of the spool
housing to unhook the bottom cap.
3. Take out the spool and pull off the old line. Put one
end of new line through the spool holes and pull it
until the length is equal between each part of the line.
4. Wind up the line in the correct direction as indicated
on the spool.
5. Hook each end of the line in the slot on the edge of
the spool, and then put the ends through the eyelets
on the housing. Make sure that the spring and the
washers are in place.
6. While holding the spool against the housing, pull the
line ends to release them from the slot.
7. Line up the slot on the bottom cap with the hook on
the housing, press the cap against the housing until it
clicks.

BLADES
•When refilling the tank or resting, it is often a good
idea to use the time to oil the cutting blades.
• If a gap exists between the upper and lower blades,
follow the procedure below to adjust them so that they
fit more closely together.
(1) Upper blade (2) Lower blade
1. Loosen lock nut (A) as shown in the diagram.
2. Tighten screw (B) fully, and then turn one-third to one-
half of a rotation backward.
3. While holding onto the screw to keep it in position,
tighten the lock nut.
4. Check to make sure that the flat washer (C) is loose
enough so that it may be turned by pressing on it with
a finger.
Maintenance
ANGLE TRANSMISSION
•The reduction gears are lubricated by multipurpose,
lithium-based grease in the angle transmission. Sup-
ply new grease every 25 hours of use or more often
depending on the job condition.
• Remove the cutter holders before installing new
grease to arrange for old grease to exit.
