Mixing Fuel

CAUTION!

Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may cause increased operating tem- peratures. Under certain conditions, alcohol-based gasoline may also reduce the lubricating qualities of some 2-cycle mixing oils. Never use any type of gaso- line containing more than 10% alcohol by volume! Generic oils and some outboard oils may not be intended for use in high- performance C4 engines, and should never be used in your Shindaiwa engine.

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 exces- sive carbon deposits.

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

nMix 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

n1 gallon of gasoline to 2.6 oz. mixing oil

n5 liters of gasoline to 100 ml. mixing oil

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 classi- fied oil and also meets or exceeds ISO-L-EGD performance requirements. Shindaiwa One is recommended for use in all Shindaiwa low emis- sions engines and also includes a fuel stabilizer.

Filling the Fuel Tank

WARNING!

Minimize the Risk of Fire

nNEVER smoke or light fires near the engine.

nALWAYS stop the engine and allow it to cool before refueling. Avoid overfill- ing and wipe off any fuel that may have spilled.

nALWAYS inspect the unit for fuel leaks before each use. During each refill, check that no fuel leaks from around the fuel cap and/or fuel tank.

If fuel leaks are evident, stop using the unit immediately. Fuel leaks must be repaired before using the unit.

nALWAYS move the unit at least 10 feet (3 meters) away from a fuel stor- age area or other readily flammable materials before starting the engine.

nNEVER place flammable material close to the engine muffler.

nNEVER operate the engine without the muffler and spark arrester screen in place.

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

2.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.

Starting the Engine

IMPORTANT!

Engine ignition is controlled by a two position switch mounted on the throttle housing labeled, "I" for ON or START and "O" for OFF or STOP.

3. Press the primer bulb until fuel can be

seen flowing in the transparent return

tube.

1.Slide the ignition switch to the “ON” position. See Figure 16.

2.Set the throttle lever to the “fast idle”;

a.Squeeze the throttle lever toward the handgrip.

b.Depress and hold the throttle lock button.

c.While depressing the throttle lock button, release the throttle lever. See Figure 16.

IMPORTANT!

The primer system only pushes fuel through the carburetor. Repeatedly pressing the primer bulb will not flood the engine with fuel.

4.Set the choke lever to the

CLOSED position if en-

gine is cold.

5.While holding the outer tube firmly with left hand. Use your other hand to slowly pull the recoil starter handle until resis- tance is felt, then pull quickly to start the engine.

CAUTION!

Do not pull the recoil starter to the end of the rope travel. Pulling the recoil starter to the end of the rope travel can damage the starter.
