blower and tubes for damage,
including loose or missing compo-
nents, and repair as necessary.

plug with a Champion CJ8 or
equivalent, gapped to 0.024 inch

CAUTION!
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
servicing the spark plug! Cylinder
threads can be damaged by tight-
ening or loosening the spark plug
while the engine is hot!

wire to extract the fuel filter from in-
side the fuel tank, and then remove
and replace with a new element. See
figure 14.
CAUTION!
Do not nick or perforate fuel tube
with wire hook!
Before reinstalling the filter, inspect
the condition of the fuel line. If
damage or deterioration are noted,
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.
1. Use the spark plug wrench to re-
move the spark plug (turn counter-
clockwise to remove). See figure
13.
2. Clean and adjust the spark plug
gap to 0.024” (0.6mm). Replace any
damaged or visibly worn plug with a
Champion CJ8 or equivalent. See
figure 13.
3. Install the spark plug finger-tight
in the cylinder head, then tighten it
firmly with the spark plug wrench.
Avoid overtightening.
