Fuels/refueling

Handling petroleum products

Utmost care is required when handling fuel. Fuel may contain substances similar to solvents. Refuel either in a well ventilated area or outdoors. Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin.

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, various skin diseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil, fuel etc.

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

The engine of the brush cutter is a high-efficiency two-stroke engine.

It is run with a mixture of fuel and two-stroke engine oil. The engine is designed to use unleaded regular fuel with a min. Octane value of 91 RON. If no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine, but may cause poor operating behavior.

A similar situation will arise from the use of leaded fuel. To obtain optimum engine performance and to protect your health and the environment, only unleaded fuel should be used!

For engine lubrication use a two-stroke engine oil (quality grade: TC-3), which is added to the fuel. The engine has been designed to use MAKITA two-stroke engine oil at mixture ratio of 25:1 to protect the environment. In addition, a long service life and reliable operation with a minimum emission of exhaust gasses is assured. It is absolutely essential to observe a mixture ratio of 25:1 MAKITA 2- stroke engine oil. Otherwise reliable function of the brush cutter cannot be guaranteed.

The correct mixture ratio:

Mix 25 parts gasoline with 1 part MAKITA 2-stroke engine oil (see table on right).

NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required in an approved can which meets or exceeds all local code standards, then add the remaining fuel.

Throughly shake the mixture before filling it into the brush cutter tank. It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder, the spark plugs as well as the muffler. In addition, fuel consumption will rise and the performance will be decreased.

Refuelling

Never perform refuelling operations in a closed, unventilated area.

The engine must be switched off!

–Thoroughly clean the area around the gas cap, to prevent dirt from getting into the fuel tank.

–Unscrew the gas cap and fill the tank with fuel.

–Never fill the fuel tank to the very top.

–Securely screw on the gas cap.

–Wipe the screw plug and tank with an absorbent after refuelling! Allow cloths to dry and discard in a proper container.

Storage of Fuel

Fuel cannot be stored for an unlimited period of time.

Purchase only the quantity required for a 4 week operating period. Only use approved fuel storage containers.

Observe the Safety Instructions on page 4!

Putting into operation

Observe the applicable accident prevention regulations!

Starting

Move at least 3m (10ft) away from the place of refuelling. Place the brush cutter on a clean piece of ground taking care that the cutting tool does not come into contact with the ground or any other objects.

	Cold start
			(4)
	– Push the I-O switch (1) in the direction shown by the arrow.
	–	Grasp the handle (hand pressure activates the safety lock-off lever (2)).
	–	Press the throttle lever (3) and hold it down.	(3)
	– Press the lock button (4) and release the control lever, and then release the
		lock button (the lock button holds the throttle lever in the start-up position).	(1)
			(2)

–First place the machine on the ground.

–Open the fuel valve. The valve opens when the lever (5) is at right angles to the ground (6). The valve closes when the lever is parallel with the ground (7).

–Move the choke lever (8) to the top position ( ).

–Firmly hold the clutch case by your left hand, as illustrated.

–Slowly pull the starter grip until resistance is felt and continue with a smart pull.

–Do not pull out the starter rope to its full extent and do not allow the starter handle to be retracted without control, but ensure that it is retracted slowly.

–Repeat the starting operation until initial ignitions are heard.

– Depress the choke lever (	) and pull the starter rope again until the engine
starts.

–As soon as the engine starts, immediately tap and release the throttle, thus releasing the half-throttle lock so that the engine can run in idle.

–Run the engine for approximately one minute at a moderate speed before applying full throttle.

Caution during operation:

If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 /min or more. Never operate the engine at a higher speed than required and at an approximate speed of 6,000 - 8,000 /min.

Starting the warm engine

–As described above, except without moving the choke lever (choke lever remains in the down position).

Stopping

–Release the control lever (3) fully, and when the engine speed has lowered, push the I-O switch (1) to “O” position the engine will now stop.

(3)(1)

14

IDLE ADJUSTMENT

The cutter blade or the nylon cutting head should not run when the control lever is fully released. If necessary, adjust the idle rpm using the idle adjusting screw.

Checking the Idling speed

–Idle speed should be set to 2,600 /min.

If necessary correct it by means of the idle screw (the blade or the nylon cutting head must not turn when the engine is at idle).

Screwing in the screw (1) will cause an increase in the engine speed, whereas backing off the screw will reduce the engine speed.

Resharpening the cutting tool

CAUTION: The cutting tools mentioned below must only be resharpened by an authorized facility. Manual resharpening will result in imbalances of the cutting tool causing vibrations and damage to the equipment.

– cutter blade (star blade (4 teeth), eddy blade (8 teeth), saw blade)

An expert resharpening and balancing service is provided by Authorized Service Agents.

NOTE: To increase the service life of the cutter blade (star blade, eddy blade, saw blade) it may be turned over once, until both cutting edges have become blunt.
