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.
An Emission Control Label is located on the unit. (This is an EXAMPLE ONLY; information on label varies by engine 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
specied in those manuals.
TM
2-Stroke oil or Red ArmorTM engine oil may be mixed at 50:1
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, 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
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 shut-off containers to reduce fuel spillage.
Filling the Fuel Tank
WARNING!
Minimize the Risk of Fire
NEVER ■ smoke or light res near the
engine.
■ stop the engine and allow
ALWAYS
it to cool before refueling.
■ Wipe all spilled fuel and
ALWAYS
move at least 3 meters (10 feet)
from the fueling point and source
before starting.
■ place ammable material
NEVER
close to the engine mufer.
■ operate the engine with-
NEVER
out the mufer and spark arrester
screen in place and in good working condition.
FUEL IS HIGHLY FLAMMABLE. ■
ALWAYS ■ store gasoline in a
container approved for ammable liquids.
ALWAYS ■ inspect the unit for
fuel leaks before each use.
During each rell, check that
no fuel leaks from around the
fuel cap and/or fuel tank.
If fuel leaks are evident, stop
using the unit immediately.
Fuel leaks must be repaired
before using the unit.
ALWAYS ■ move the unit at
least 3 meters (10 feet) away
from a fuel storage area or
other readily ammable materials before starting
the engine.
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.
