Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:
Clean external parts thoroughly.
Ŷ
Drain all the fuel from the carburetor
Ŷ
and the fuel tank.
Long Term Storage
Remove remaining fuel from the fuel
Ŷ
lines and carburetor with the fuel
drained from the fuel tank. To do so:
Prime the primer bulb until no more 1.
fuel is passing through.
Start and run the engine until it stops 2.
running.
Repeat steps 1 and 2 until the engine 3.
will no longer start.
Remove the spark plug and pour
Ŷ
about 7 mL (1/4 oz.) of 2-cycle mixing
oil into the cylinder through the spark
plug hole. Slowly pull the recoil starter
2 or 3 times so oil will evenly coat the
interior of the engine. Reinstall the
spark plug.
IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL.
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
Before storing the unit, repair or
Ŷ
replace any worn or damaged parts.
Remove the air cleaner element from
Ŷ
the carburetor and clean it thoroughly
with soap and water, let dry and reas-
semble the element.
Store the unit in a clean, dust-free area.
Ŷ
Maintenance (continued)
IMPORTANT!
If a new gasket is not available and/or the
old gasket is not damaged, the old gasket
may be reused. Never use cracked or
damaged gaskets!
Turn engine over several times, and 6.
returnthe to TDC-compression.
Recheck with proper feeler gauge to
make sure clearance adjustment did
not change as a result of tightening the
locknut. Readjust as necessary.
Replace rocker arm cover gasket to 7.
assure proper sealing and install cover.
Remove cylinder cover, rocker arm cover, 1.
and spark plug. Rotate the crankshaft
while observing the piston through the
spark plug opening. When the piston
is at the top of the compression stroke
(TDC), the valves can be adjusted.
Loosen adjuster locknut so that the 2.
2.5 mm Allen socket head adjustment
screw can turn freely.
Insert 0.10 mm feeler gauge between 3.
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 in 5.
place with the Allen driver, tighten the
locknut with a wrench.
CAUTION!
Performing a valve adjustment
Ŷ
incorrectly may cause hard start-
ing and/or can damage the engine.
If you are unfamiliar with this
Ŷ
engine or uncomfortable with this
procedure, consult with an autho-
rized Shindaiwa servicing dealer.
Valve Adjustment
139/150-Hour Maintenance
Maintenance after first 139-hours,
then ever y 150-hours thereafter.
Combustion chamber should be decar-
Ŷ
bonized, 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
Ŷ
only the type recommended in the
”Specifications” section or an equivalent
resistor type spark plug of the correct
heat range. Set spark plug electrode
gap to 0.6 -0.7 mm.
The valve clearance should be adjusted
Ŷ
annually or every 135 hours. It is
highly recommended that this is
done by a Shindaiwa-trained service
technician.
