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 certi-
ed oil will void the engine warranty.
IMPORTANT!
Shindaiwa Red Armor
TM
engine oil may be mixed at 50:1 ratio for application
in all Shindaiwa engines sold in the past, regardless of ratio specied in those
manuals.
Examples of 50:1 mixing quantities
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, improp-
erly 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 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.
• 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 ames.
IMPORTANT!
Stored fuel may separate. ALWAYS shake fuel container
thoroughly before each use.
Filling the fuel tank
CAUTION!
Slowly remove the fuel cap only after stopping the engine
WARNING!
Minimize the Risk of Fire
NEVER ■ smoke or light res near the engine.
■ stop the engine and allow it to cool before
ALWAYS
refueling.
■ Wipe all spilled fuel and move at least 3
ALWAYS
meters (10 feet) from the fueling point and source before
starting.
■ place ammable material close to the engine
NEVER
