n INSPECTION Inspect the entire blower
and tubes for damage, including loose
or missing components, and repair as
necessary.
n SPARK PLUG Replace the spark plug
with a NGK CMR5H (or equivalent),
gapped to 0.6 mm (0.024").
n FUEL FILTER Use a hooked wire to
extract the fuel filter from inside the fuel
tank. See Figure 20.
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.
139/150-Hour Maintenance
Maintenance after first 139-
hours, then every 150-hours
thereafter.
n 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.
CAUTION!
to remove.
Never allow dirt or debris to enter the
cylinder bore! Before removing the
spark plug, thoroughly clean the spark
plug and cylinder head area!
Allow the engine to cool before servic-
ing the spark plug! Cylinder threads
can be damaged by tightening or loos-
ening the spark plug while the engine
is hot!
electrode.
n Inspect the filter element for signs of
contamination from debris. A contami-
nated fuel filter should be replaced with
a n ew S hindaiwa r eplacement el ement.
Before reinstalling the filter, inspect the
condition of the fuel line. If you note
damage or deterioration, the blower
should be removed from service until it
can be inspected by a Shindaiwa-trained
service technician.
n COOLING SYSTEM Use a wood or
plastic scraper and a soft brush to
remove dirt and debris from the cylinder
fins and crankcase.
n Replace the spark plug annually: Use
only NGK CMR5H or equivalent
resistor type spark plug of the correct
heat range. Set spark plug electrode gap
to 0.6 mm (0.024").
1. Use the spark plug wrench to remove
the spark plug. See Figure 19.
2. Clean and adjust the spark plug gap
to 0.6mm (0.024"). If the plug must be
replaced, use a NGK CMR5H or equiva-
lent type plug of the correct heat range.
3. Install the spark plug finger-tight in the
cylinder head, then tighten it firmly
with the spark plug wrench. If a torque
wrench is available, torque the spark
plug to 170-190 kgf.cm.
