Mixing Fuel

CAUTION!

Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may cause increased operating temperatures. Under certain conditions, alcohol-based gasoline may also reduce the lubricating qualities of some 2-cycle mixing oils. Never use any type of gasoline containing more than 10% alcohol by volume! Generic oils and some outboard oils may not be intended for use in high-performance air cooled 2-cycle engines, and should never

be used in your Shindaiwa engine.

Filling the Fuel Tank

CAUTION!

This engine is designed to operate on a 50:1 mixture consisting of unleaded gasoline and ISO-L-EGD or JASO FC class 2-cycle mixing oil only. Use of non-approved mixing oils can lead to excessive carbon deposits.

■Use only fresh, clean unleaded gasoline with a pump octane of 87 or higher.

■Mix all fuel with a 2-cycle air-cooled mixing oil that meets or exceeds ISO-L- EGD and/or JASO FC classified oils at 50:1 gasoline/oil ratio.

Examples of 50:1 mixing quantities

■1 gallon of gasoline to 2.6 oz. mixing oil

■5 liters of gasoline to 100 ml. mixing oil

WARNING!

Minimize the risk of fire!

■STOP engine before refueling.

■ALWAYS allow the engine to cool before refueling!

■Wipe all spilled fuel and move the engine at least 10 feet (3 meters) from the fueling point and source before restarting!

■NEVER start or operate this unit if there is a fuel leak.

■NEVER start or operate this unit if the carburetor, fuel lines, fuel tank and/or fuel tank cap are damaged.

■NEVER smoke or light any fires near the engine or fuel source!

■NEVER place any flammable material near the engine muffler!

■NEVER operate the engine without the muffler and spark arrester in good working condition.

IMPORTANT!

Mix only enough fuel for your immediate needs! If fuel must be stored longer than

30 days and

oil with fuel stabilizer is

not used, it should first be treated with a fuel stabilizer such as STA-BIL™.

Oil is a registered JASO FC classified oil and also meets or exceeds ISO-L-EGD performance requirements. Shindaiwa One is recommended for use in all Shindaiwa low emissions engines. Shindaiwa One also includes a fuel stabilizer.

1. Place the trimmer on a flat, level surface.

. Clear any dirt or other debris from around the fuel filler cap.

3.Remove the fuel cap, and fill the tank with clean, fresh fuel.

4.Reinstall the fuel filler cap and tighten firmly.

IMPORTANT!

If the engine fails to start after several attempts with the choke in the closed position, the engine may be flooded with fuel. If flooding is suspected, move the choke lever to the open position and repeatedly pull the recoil starter to remove excess fuel and start the engine.

If the engine still fails to start, refer to the troubleshooting section of this manual.

When the Engine Starts...

■After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit.

■Advancing the throttle makes the cutting attachment turn faster; releasing the throttle permits the attachment to stop turning. If the cutting attachment continues to rotate when the engine returns to idle, carburetor idle speed should be adjusted (see “Adjusting Engine Idle” below).

Stopping the Engine

Idle the engine briefly before stopping (about 2 minutes), then slide the ignition switch to the “O” (Engine OFF) position.

Figure 16

Adjusting Engine Idle
	Idle Adjusting
Figure 17	Screw

The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment.

Idle Speed Adjustment

WARNING!

The cutting attachment must NEVER rotate at engine idle! If the idle speed cannot be

adjusted by the procedure described here, return the trimmer to your Shindaiwa dealer for inspection.

1.Place the trimmer on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm.

. If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise. See Figure 17.

3.If a tachometer is available, the engine idle speed should be final adjusted to 3,000 (±250) rpm (min-1).

4.Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field.

Checking Unit Condition

NEVER operate the unit with the cutting attachment shield or other protective devices removed!

WARNING!

A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!

Use only authorized Shindaiwa parts and accessories with your Shindaiwa trimmer. Do not make modifications to this unit without written approval from Shindaiwa, Inc.

ALWAYS make sure the cutting attachment is properly installed and firmly tightened before operation.
