Mixing Fuel


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


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.


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


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.


Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shut-off 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.


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

Filling the Fuel Tank

1.Place the blower 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.

5.Wipe away any spilled fuel before starting the blower.

Starting the Engine


Danger from rotating impeller!

The impeller will rotate whenever the blower is operated! Never operate this blower unless the intake cover and blower tubes are properly installed and in good working order!


Danger from thrown dust or debris!
