REFUELING

WARNING

Refuel the fuel tank in a flat place outdoors. Avoid smoking or bringing any flame or spark near the fuel, and stub out any cigarette.

When refueling the fuel tank while using this machine, make sure to stop the engine and allow it to cool before refueling the fuel tank.

Make sure to tighten the fuel-tank cap firmly.

Wipe up all fuel spills with a dry cloth before starting the engine.

IMPORTANT

Fill the fuel tank to roughly 80% of its capacity.

If filled too full, the fuel may leak from the tank cap while using this machine.

1.Place the brushcutter to be refueled in a flat place outdoors, and make sure it is stable.

2.Unscrew the fuel-tank cap a little, and allow the difference of atmospheric pressure between the inside and outside of the fuel tank to equalize.

3.Remove the fuel-tank cap, and fill fuel little by little up to roughly 80%.

4.After filling the fuel, close the fuel-tank cap tightly, and make sure that the fuel does not leak.

STARTING THE ENGINE

WARNING

Before starting the engine after filling with fuel, move the machine at least 3 m away from where it was refueled.

Starting the engine where the machine was refueled might cause a fire.

Do not start the engine indoors or in any place which is not well ventilated. Otherwise, you might suffer carbon monoxide poisoning which could injure you.

WARNING

Keep the throttle lever set always to the idling position when starting or stopping the engine, or moving the machine. If the throttle lever is set to any position other than the idling position, the blade will begin to rotate, causing danger.

The engine might start after a delay. Hold the unit until it starts.

WARNING

Before starting the engine, check the entire unit for troubles such as looseness in installing the handle, malfunctioning of the throttle lever, looseness in installing the blade, and fuel leaks.

When starting the engine, place the machine on the ground and hold it securely. Since the blade might touch the ground or object near the machine, do not start the engine while holding up the machine with one hand.

Do not start the engine with the throttle lever kept pulled because the blade will immediately begin to move upon starting the engine. When starting the engine, place the machine on a flat and firm place, and keep all objects away from the blade.

When starting the engine, keep all objects away from the machine so that the blade does not touch the ground.

If the blade continues to rotate even after the throttle lever is returned to the idling position, stop the engine and check the idling adjustment screw of the throttle wire and the carburetor.

When the engine has started, make sure that the blade does not move. If the blade continues to move, stop the engine, and check the idling adjustment screw of the throttle wire and the carburetor.

While using the machine, hold the grips of the machine with both hands, and keep your eyes on the blade.

Do not touch the metal part of the engine body and the muffler while using the machine or immediately after stopping using it, otherwise you might suffer burns.

Do not touch the spark plug or plug cord while using the machine, otherwise you might suffer an electric shock.

IMPORTANT

If you repeat the starting operation with the choke closed, the electrode of the spark plug may become wet and the engine might not start. If this happens, open the choke, set the throttle lever to the almost fully-open
