50-hour Maintenance
Ever y 50 hours of operation
(more frequently in dusty or dirty
conditions):
Remove and clean the cylinder cover
and clean grass and dirt from the
cylinder fins.
Use a hooked wire to extract the fuel
filter from inside the fuel tank.
See Figure 3.
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.
Remove and replace the filter element.
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.
