Priming

Before the pump can develop suction or “lift” at the water source, the pump impeller must first be primed by filling the pump housing with water. Once the water pump has been primed, additional priming should be required only if the pump has been drained or otherwise emptied.

1.Remove the filler plug at the top of the pump housing. Use care not to lose the sealing ring beneath the filler plug.

IMPORTANT!

A damaged or missing filler plug seal may allow air to leak into the pump housing. Air leakage can lower performance!

2.Fill the pump housing through the priming port with clean water until water overflows from the filler plug hole on the pump body.

3.Replace and securely tighten the filler plug.

CAUTION!

Never allow the pump to run dry! Operation without water can permanently damage the pump seals.

Mixing Fuel

WARNING!

Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.

Fuel Requirements

Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol) is NOT approved.

Hybrid 4TM Mixture Oil - Engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards must be used. Shindaiwa highly recommends using Shindaiwa Red ArmorTM engine oil in all Shindaiwa Hybrid 4TM engines to protect the engine from harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa Red ArmorTM engine oil exceeds ISO-L-EGD and J.A.S.O. M345/FD performance requirements. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certified oil will void the engine warranty.

 

Examples of 50:1 mixing quantities

IMPORTANT!

Shindaiwa Red ArmorTM engine oil may be mixed at 50:1 ratio for application in all Shindaiwa engines sold in the past, regardless of ratio specified in those manuals.

IMPORTANT!

Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a fuel stabilizer is added. Use of unmixed, improperly mixed, or stale fuel, may cause hard starting, poor performance, or severe engine damage and void the product warranty. Read and follow instructions in the Long Term Storage section of this manual.

Handling Fuel

DANGER

Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result.

Use an approved fuel container.

DO NOT smoke near fuel.

DO NOT allow flames or sparks near fuel.

Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.

NEVER refuel a unit when the engine is HOT or RUNNING!

DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.

DO NOT overfill fuel tank. Wipe up spills immediately.

Securely tighten fuel tank cap and close fuel container after refueling.

Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.

Move at least 3m (10 ft.) from refueling location before starting the engine.

Mixing Instructions

1.Fill an approved fuel container with half of the required amount of gasoline.

2.Add the proper amount of engine oil to gasoline.

3.Close container and shake to mix oil with gasoline.

4.Add remaining gasoline, close fuel container, and remix.

IMPORTANT!

Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage.

After use

DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused fuel to an approved fuel storage container.

Storage - Fuel storage laws vary by locality. Contact your local government for the laws affecting your area. As a precaution, store fuel in an approved, airtight container. Store in a well-ventilated, unoccupied building, away from sparks and flames.

IMPORTANT!

Stored fuel may separate. ALWAYS shake fuel container thoroughly before each use.

Filling the fuel tank

WARNING!

Minimize the Risk of Fire

NEVER smoke or light fires near the engine.

ALWAYS stop the engine and allow it to cool before refueling.

ALWAYS Wipe all spilled fuel and move at least 3 meters (10 feet) from the fueling point and source before starting.

NEVER place flammable material close to the engine muffler.

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

FUEL IS HIGHLY FLAMMABLE.

ALWAYS store gasoline in a container approved for flammable liquids.

ALWAYS 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.

ALWAYS move the unit at least 3 meters (10 feet) away from a fuel storage area or other readily flammable materials before starting

the engine.

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

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

CAUTION!

Slowly remove the fuel cap only after stopping the engine

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

4.Reinstall the fuel filler cap and tighten firmly.

5.Wipe away any spilled fuel before starting engine.

Starting the Engine

WARNING!

Do not run engine in an enclosed area. Exhaust gas contains carbon monoxide, an odorless and deadly poison.

IMPORTANT!.

Do not start or run the pump without priming the pump with water. Serious damage to the pump seals will occur when the pump is run dry.

1.Place suction intake and strainer in the water to be pumped prior to starting engine.

2.Set throttle control lever to the half open position. See Figure 3.

3.Press the primer bulb until fuel can be seen flowing in the transparent return tube. See Figure 4.

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 the engine is cold.

5.While holding the pump handle firmly with your left hand, use your other hand to slowly pull the recoil starter handle until resistance is felt, then pull quickly to start the engine. See Figure 6

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.

6.When the engine starts, slowly move the choke lever to the "OPEN" position. See Figure 7. (If the engine stops after the initial start, close the choke and restart.)
