FUELS/REFUELING
Handling fuel
Utmost care required when handling fuel. Fuel may contain substances similar
to solvents. Refuel either in a well
ventilated room or outdoors.
Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin.
Mineral oil products degrease you skin. If your skin contacts with these
substances repeatedly and for an extended
period of time, it will desiccate. Various skin diseases may result. In
addition, allergic reactions may occur. Eyes can be irritated by contact with
oil. If oil comes into your eyes, immediately wash them with clear water. If
your eyes are still irritated, see a doctor immediately.
Fuel and oil mixture
This brush-cutter (string-trimmer) is powered by a high-efficiency two-stroke
engine being run with a mixture of fuel and two-stroke engine oil. The engine
is designed for unleaded gasoline intended for automotive use with an
octane rating of 87 or higher.
For lubricating the engine, use any brand of premium 2-stroke engine oil
classified as grade ISO-L-EGD or JSAO-
FC to be added to the fuel. Using any other oil will shorten the engine life
and increase the required maintenance.
It is absolutely required to observe a mixture ratio of 50 : 1 (2-stroke
engine oil specified above), unless otherwise reliable function of the brush
cutter ( or string trimmer ) cannot be guaranteed.
Correct Fuel Mixture ( 50 : 1 )
Note :
When doing the fuel-oil mixture, first mix the entire oil quantity with half
of the fuel required, then add the remaining fuel. Before filling it into the
brush-cutter ( string trimmer ) tank, thoroughly shake the mixture. It is not
recommended to add more engine oil than specified to ensure safe operation.
This will result in a higher production of combustion residues which will
pollute the environment and clog the exhaust channel in the cylinder as well
as the muffler.
In addition, the fuel consumption will rise and the performance will decrease.
Refuelling
Follow the appropriate manners described on page 6.
Storage of Fuel
Fuel cannot be stored for an unlimited period of time.
Purchase only the quantity required for a 4 week operating period. Use only
approved fuel storage containers.
CORRECT HANDLING OF MACHINE
Attachment of shoulder strap
Always wear the shoulder strap and adjust the strap length so that the cutter
blade is kept parallel with the ground.
Detachment
The shoulder strap has a quick release latch. In an emergency, pull the red
strap (A) to detach the machine from
you. Be extremely careful to maintain control of the machine at this time. Do
not allow the machine to be deflected
toward you or anyone in the work vicinity.
WARNING : Failure to maintain complete control of the machine may result in
serious bodily injury or death.
To reassemble, remove the spring clip (B) from the machine, place open end
over the strap buckle (C) and then
insert the release blade (D).
POINTS IN OPERATION AND HOW TO STOP

accident. It should be done by the
Authorized Service Agent.
To ensure a long service life and to avoid any damage to the machine, the
following servicing operations should be done at regular intervals.
Daily checkup and maintenance
Before operation, check the machine for loose screws or missing parts. Pay
your special attention to the tightness of the cutting tool.
Before operation, always check for clogging of the cooling air passage and the
cylinder fins. Clean them if necessary.
Do the following works daily after use :
- Clean the machine externally and inspect for damage.
- Clean the air filter. When working under extremely dusty conditions, clean the filter several times a day.
- Check the blade or the nylon cutting head for damage and make sure it is firmly mounted.
- Check if there is sufficient difference between idling and engagement speed. Make sure that the cutting tool does not rotate while the engine is idling.
- Check the functioning of the I-O switch, the lock-off lever, the control lever and the lock button.
Cleaning of air-filter
- Remove screw (B).
- Remove the air filter cover (A). Take out the air-filter (C) and clean it in warm soapy water. Dry the air-filter completely.
- After cleaning, put back the air filter cover and fasten it with the screw.
Note :
If there is excessive dust or dirt adhering to the air filter, clean it every
day. A clogged air filter may make it difficult or impossible to start the
engine or increase the engine rotation-speed.
Checking the spark plug
Only use the supplied universal wrench to remove or install the spark plug.
The gap between the two electrodes of the spark plug should be 0.6 – 0.7 mm (
0.024” – 0.028” ). If the gap is too
wide or too narrow, adjust it. If the spark plug is clogged with carbon or
fouled, clean it completely or replace it.
CAUTION :
Never touch the spark plug connector while the engine is running ( danger of
high voltage electric shock ).
Supply of grease to gear case
Supply grease (Shell Albania 3 or equivalent ) to the gear case through the grease hole every 30 hours.
Suction head in the fuel tank
The fuel filter (A) of the suction head is for filtering the fuel to the
carburetor.
A periodical visual inspection of this fuel filter is highly recommended.
To inspect the fuel filter, open the tank cap and pull out the suction head
through the opening of the tank using a wire hook.
If the filter is found to have hardened, polluted or clogged up, it should be
replaced.
Insufficient fuel supply caused by the deteriorated filter will result in the
poor performance of the engine. It is therefore important to replace the fuel
filter at least quarterly to ensure fuel-supply to the carburetor.
Cleaning of muffler exhaust port
Check the muffler exhaust port (B) regularly. If it is clogged by carbon
deposits, scratch out the deposits carefully with a suitable tool.
STORAGE
When the Brush Cutter/String Trimmer is in storage for a long time
-
