Emission Control (exhaust & evaporative)
EPA 2010 and Later and/or C.A.R.B. TIER III
The emission control system for the engine is EM/TWC (Engine Modication and 3-way Catalyst) and for the fuel tank
the Control System is EVAP (Evaporative Emissions) or N (for nylon tank). Evaporative emission may be applicable to
California models only.
Emission Control Label (located on Engine) (EXAMPLE ONLY, information on label varies by FAMILY).
PRODUCT EMISSION DURABILITY (EMISSION COMPLIANCE PERIOD)
The 300 hour emission compliance period is the time span selected by the manufacturer certifying the engine
emissions output meets applicable emissions regulations, provided that approved maintenance procedures are
followed as listed in the Maintenance Section of this manual.

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
failure 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 performance, 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

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 shut-off
containers to reduce fuel spillage.
