Fuel filter
Take the filter out of the fueling port using a small wire
hook. Disconnect the filter assembly from the fuel pipe
and unhook the retainer to disassemble it. Clean the
components with gasoline.
IMPORTANT! A clogged fuel filter may cause
poor acceleration of the engine.
Spark plug
Remove and inspect the spark plug and clean the elec-
trodes as necessary with brush.
The spark gap should be adjusted to 0.6~0.7mm.
Intake air cooling vent
Check the intake air-cooling vent and the area around
the cylinder cooling fins, and remove any waste, which
has attached itself to the brush cutter.
IMPORTANT! Note that failing to do so could
cause the muffler to become overheated, and
that this in turn could cause the brush cutter
to catch on tire.
Gear case
Supply multi-purpose grease at every 25 hours of use.
Remove the cutter holders to arrange for old grease
to exit.
AFTER 100 HOURS OF USE
Muffler
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 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.
4. Remove the float cabin of the carburetor and clean
the inside.

ADJUSTING CARBURETOR
IMPORTANT! A wrong adjustment may cause
damage to your unit. If the engine does not
run well after adjusting the carburetor, please
contact the shop where you purchased the product.
Idle adjustment screw
This is the screw to adjust the engine rotation when
the throttle lever is set to the lowest speed position. If
you turn right (clockwise), rotation increases, and left
(counterclockwise) decreases. In case the blade con-
tinues to rotate or engine stops when you return the
throttle lever completely to the original position, make
readjustment.
MAINTENANCE BEFORE STORAGE
1. Brushing off dirt form the machine, check damage
or slack of each part. If you find out abnormalities,
repair them for the next use.
2. Extract fuel from the tank, and loose the drain
screw of the float cabin to extract fuel, turn on the
engine, and leave it running until it stops naturally.
3. Remove the spark plug and put in 1-2cc of 2-cycle
oil in the engine. Draw the starter rope 2-3 times,
set the plug back, and stop it at the contraction po-
sition.
4. Apply anti-rust oil to the metal parts such as the
throttle wire, put the cover on the blade, and keep it
indoor avoiding dampness.
