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.
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 specically
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 certied oil will void the engine warranty.
Mixing Fuel
Assembly (continued)
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 ArmorTM engine oil may be mixed at 50:1
ratio for application in all Shindaiwa engines sold in the past, regardless of ratio
specied 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.

Gearcase lubrication
Lubricate the Flexible Shaft
Lack of lubrication will cause rapid
wear to the exible shaft and also
to the shaft tube liner, resulting
in increased vibration and greatly
decreased service life. Remove and
lubricate the exible shaft as follows:
50-hour Maintenance
Hooked wire
Fuel lter element
Remove and replace the fuel lter element
Every 50 hours of operation; more
frequnetly in dusty conditions:
■Remove and clean the cylinder
cover and clean dirt and debris
from the cylinder cooling ns.
Remove and replace the fuel lter
element.
■Use a hooked wire to extract the
fuel lter from inside the fuel tank.
Inspect the fuel lter element. If
it shows signs of contamination,
replace with a genuine Shindaiwa
replacement fuel lter element.
CAUTION!
Make sure you do not pierce the fuel
line with the end of the hooked wire.
The line is delicate and can be dam-
aged easily.
■Before reinstalling the new lter ele-
ment, inspect the condition of all the
fuel system components (fuel pick-
up line, fuel return line, tank vent
line, tank vent, fuel cap and fuel
tank). If damage, splitting or dete-
rioration is noted, the unit should
be removed from service until it can
be inspected or repaired by a Shin-
daiwa-trained service technician.
NOTE:
Federal EPA regulations require all model year 2012 and later gasoline powered
engines produced for sale in the United States to be equipped with a special low
permeation fuel supply hose between the carburetor and fuel tank. When servic-
ing model year 2012 and later equipment, only fuel supply hoses certied by EPA
can be used to replace the original equipment supply hose. Fines up to $37,500
may be enforced for using an un-certied replacement part.

Carburetor Adjustment
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be
made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can
be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to 1,100
feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 1,100 feet ASL
the carburetor may need to be adjusted by an authorized Shindaiwa service dealer.
NOTE:
Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments,
other than idle speed, must be performed by an authorized Shindaiwa dealer.
IMPORTANT!
If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when operating the
engine below 1,100 feet ASL, otherwise severe engine damage may result.
Every 90 hours of operation, remove
and clean the mufer.
If the engine becomes sluggish and
low on power, check and clean the
spark arrester screen.
WARNING!
Never operate the unit
with a damage or missing muf-
er or spark arrester! Operating
with a missing or damaged spark
arrester is a re hazard and could
also damage your hearing.
1. Remove the spark plug boot.
2. Remove the engine cover and muf-
er cover.
3. Remove the spark arrester screen
and cover.
4. Clean the screen with a stiff bristle
brush.
5. Remove the mufer.
6. Inspect the cylinder exhaust port for
any carbon buildup.
7. Gently tap the mufer on a wood
surface to dislodge any loose
carbon.
8. Reassemble the spark arrester,
mufer and engine cover in the
reverse order of disassembly.
IMPORTANT!
