CAUTION
Never use any type of gasoline contain-
ing more than 10% alcohol by volume!
Some types of gasoline contain alcohol
as an oxygenate. Oxygenated gaso-
line may cause increased operating
temperatures. Under certain condi-
tions, alcohol-based gasoline may also
reduce the lubricating qualities of some
2-cycle mixing oils.
Generic oils and some outboard
oils should never be used in your
Shindaiwa engine.
Mixing fuel
Filling the fuel tank
CAUTION
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and ISO-L-EGD or JASO FD
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
Use only fresh, clean unleaded gasolineŶwith a pump octane of 87 or higher.
Mix all fuel with a 2-cycle air-cooled
Ŷmixing oil that meets or exceeds ISO-L-
EGD and/or JASO FD classified oils at
50:1 gasoline/oil ratio.
Examples of 50:1 mixing quantities
WARNING!
Minimize the Risk of Fire
IMPORTANT!
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than 30
days and oil with fuel stabilizer is not
used, it should first be treated with a fuel
stabilizer such as STA-BIL™.
Oil is a registered JASO FD classi-
fied oil and also meets or exceeds ISO-L-EGD
performance requirements. Shindaiwa One is
recommended for use in all Shindaiwa low emis-
sions engines. Shindaiwa One also includes a

Spark Plug
Keep the spark plug and wire connections
tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Air Filter
The C4 engine that powers your Shindaiwa
model is a hybrid 4-stroke engine. As a
hybrid, the engine is lubricated by oil
mixed with the gasoline and air from the
carburetor that moves through and around
the internal parts of the engine in a similar
way that a 2-stroke engine is lubricated.
Without the heavy duty 2-stage air filter
equipped on all C4 engines, dust and
dirt could also move through the engine,
decreasing engine life, increasing valve
wear and the need for more frequent valve
adjustments. To keep your C4 engine
strong and reliable, Shindaiwa recom-
mends that you check and service the air
filter as instructed in the 10-Hour Mainte-
0XIÁHU
This unit must never be operated with a
faulty or missing spark arrester or muf-
fler. Make sure the muffler is well secured
and in good condition. A worn or damaged
muffler is a fire hazard and may also cause
hearing loss.
General maintenancel
NOTE:
Using non-standard replacement parts
could invalidate your Shindaiwa warranty.

may be reused. Never use cracked or dam-
aged gaskets!
Turn engine over several times, and6. return to TDC-compression. Recheck
with proper feeler gauge to make sure
clearance adjustment did not change as
a result of tightening the locknut. Read-
just as necessary.
Replace rocker arm cover gasket to7. assure proper sealing and install cover.
NOTE:
The NGK CMR5H also meets the require-
ments for electro magnetic compliance
(EMC).
139/150-Hour Maintenance
Maintenance after first 139-hours,
then every 150-hours thereafter.
Combustion chamber should be decar-
Ŷbonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained
service technician.
Replace the spark plug annually: Use
Ŷonly NGK CMR5H or equivalent resis-
tor type spark plug of the correct heat
range. Set spark plug electrode gap to
0.6 -0.7 mm (0.024-0.028 inch).
Remove cylinder cover, rocker arm1. cover, and spark plug. Rotate the
crankshaft while observing the pis-
ton through the spark plug open-
ing. When the piston is at the top of
the compression stroke (TDC), the
valves can be adjusted.
Loosen adjuster locknut so that the2. 2.5 mm Allen socket head adjustment
screw can turn freely.
Insert 0.10 mm (0.004”) feeler gauge3. between valve stem tip and rocker arm.
Turn adjustment screw (clockwise =4. tighter, counter-clockwise = looser) until
feeler gauge is almost snug. Back off
just enough to allow gauge to slip out
with limited resistance.
While holding the adjustment screw in5. place with the Allen driver, tighten the
locknut with a wrench.
CAUTION!
Performing a valve adjustment
