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 )

Gasoline Oil
1 Gallon (US) 2.6 oz.
1 Liter 20 cc (20ml)
5 Liter 100cc (100ml)

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).

Observe the Safety Instructions on page 6.

The cutting blades mentioned below should only be re-sharpened by an authorized facility. Manual re-sharpening will result in imbalances of the blade causing abnormal vibrations and damage to the machine.

• Cutter Blade : star blade ( 4 teeth ) , eddy blade ( 8 teeth )

An expert service for re-sharpening and balancing is provided by Authorized Service Agents.

NOTE:

To increase the service life of the above cutter blade, it may be turned over once until both cutting edges have become blunt.

NYLON CUTTING HEAD

Replacing the nylon cord

1 First, stop the engine. Press on the housing latches (A) inward to lift off the cover assembly (B). Then remove the spool (D).
2 Remove any excess nylon cord from the spool.
3 Cut a length of the nylon cord that is approximately 7.5m (25') long.
4 Hook the center of new nylon cord into the notch (F) in the center of the spool, with one end of the cord extending about 80~mm ( 3'' to 3 - 1 / 8'' ) more than the other. Then wind both ends firmly around the spool in the direction of the head rotation.
5 Put the cord ends temporarily into the notched (H) when winding being finished. Leave approximate 100mm (4^ ) of the cord extended beyond the notch.
6 Place the spool into the cover. Remove the ends of the cord from the notches (H) and put them in the metal eyelets (I) on the cover.
7 Mount the spool ( cover-assembly ) in the housing so that the grooves and protrusions on the spool mach up with those in the housing ( C ). Then push the cover firmly onto the housing to secure it.

SERVICING INSTRUCTIONS

Before doing any work on the Brush Cutter/String Trimmer, always stop the engine and pull the plug cap off the spark plug.

Always wear protective gloves.

Do not attempt to remove the recoil starter by yourself, which may cause an 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 - 0.7mm (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 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,

1 Drain all fuel from the fuel tank into a container approved for gasoline. Run the engine until it stops.
2 Clean all foreign material from the machine and store it in a well-ventilated place that is not accessible to children.
