Maintenance (continued)
10/15 hour maintenance
Remove and clean or replace the
spark plug.
■
Clean the spark plug. Adjust elec-
trode gap according to the values
listed in the "Specifications" section.
If the spark plug must be replaced,
use only the type recommended in
"Specifications" or equivalent resis-
tor type spark plug of the correct
heat range.
CaUTiOn!
Before removing the spark plug,
clean the area around the plug to
prevent dirt and debris from getting
into the engine's internal parts.
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 contamination, replace with a genu-
ine 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 dam-
aged 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 deteriora-
tion is noted, the unit should be
removed from service until it can
be inspected or repaired by a Shin-
daiwa-trained service technician.

Remove and inspect spark plug
■
Replace the spark plug annually:
Use only NGK CMR5H or equiva-
lent resistor type spark plug of the
correct heat range. Set spark plug
electrode gap to 0.6 mm (0.024
inch).
Hooked wire
Federal EPA regulations require all model year 2012 and later gasoline powered
engines produced for sale in the United States to be equipped with a special
low permeation fuel supply hose between the carburetor and fuel tank. When
servicing model year 2012 and later equipment, only fuel supply hoses certified
by EPA can be used to replace the original equipment supply hose. Fines up to
$37,500 may be enforced for using an un-certified replacement part.
