Maintenance (continued)
50-hour maintenance
Remove and replace the fuel filter
element.
Use a hooked wire to extract the fuel filter
from inside the fuel tank. Inspect the fuel
filter element. If it shows signs of contam-
ination, replace with a genuine Shindaiwa
replacement fuel filter 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 damaged easily.
Before reinstalling the new filter element,
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
deterioration is noted, the unit should
be removed from service until it can be
inspected or repaired by a Shindaiwa-
trained service technician.
139/150-Hour Maintenance
Maintenance after first 139-hours,
then every 150-hours thereafter.
Combustion chamber should be decar-
bonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained
service technician.
Valve Adjustment
1. Remove cylinder cover, rocker arm cover,
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.
CAUTION!
Performing a valve adjustment
incorrectly may cause hard starting
and/or can damage the engine.
If you are unfamiliar with this
engine or uncomfortable with this
procedure, consult with an autho-
rized Shindaiwa servicing dealer.

Hooked wire
Replace the spark plug annually: Use
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.
2. Loosen adjuster locknut so that the
2.5 mm Allen socket head adjustment
screw can turn freely.
3. Insert 0.10 mm feeler gauge between
valve stem tip and rocker arm.
4. Turn adjustment screw (clockwise =
tighter, counter-clockwise = looser)
until feeler gauge is almost snug. Back
off just enough to allow gauge to slip
out with limited resistance.
5. While holding the adjustment screw in
place with the Allen driver, tighten the
locknut with a wrench.
The valve clearance should be adjusted
annually or every 135 hours. It is
highly recommended that this is
done by a Shindaiwa-trained service
technician.
6. Turn engine over several times, and
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.
7. Replace rocker arm cover gasket to
assure proper sealing and install cover.
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 dam-
aged gaskets!
