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.
2 Stroke Mixture Oil - A 2-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards
must be used. Shindaiwa OneTM 2-Stroke Oil is strongly recommended as it meets this standard and is specically
formulated for use in all Shindaiwa 2-stroke engines. Engine problems due to inadequate lubrication caused by fail-
ure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certied oil will void the engine warranty.
For increased engine protection, Shindaiwa recommends using Shindaiwa Red ArmorTM engine oil 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.
IMPORTANT!
Shindaiwa One
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 per formance, or severe engine
damage and void the product warranty. Read and follow instructions in the Long
Term Storage section of this manual.
TM
2-Stroke oil or Red ArmorTM engine oil may be mixed at 50:1
IMPORTANT!
Examples of 50:1 mixing quantities
Handling Fuel
DANGER
Fuel is VERY ammable. 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 ames 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 ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
