Mixing Fuel
A
WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa require-
ments 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, carbure-
tors 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. Shindaiwa brand Power FuelTm is 93 octane, ethanol-free fuel premixed with Shindaiwa Red Armor® engine oil
at 50:1 ratio. Use of Shindaiwa Power FuelTM is recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke
hybrid engines.
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 specifically formulated for
use in all Shindaiwa 2-stroke engines. 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.
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 OneTM 2-Stroke oil or Red ArmorrM 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, 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
A
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.
