Checking the Fuel Filter
WARNING!
KEEP AWAY FROM FIRE OR
EXCESS HEAT!
1. Remove the fuel filler cap.
2. Take the filter out from the fuel
opening by using a hooked wire. If
the filter is hard and clogged with
debris, replace it with a new one.
See Figure 30.
CAUTION!
Make sure the fuel line is not
pierced by the hooked wire. The
fuel line can be easily damaged.
3. Put the filter back into the fuel
tank. Make sure the fuel tube is not
bent and the filter stays at the
bottom of the tank.
4. Put the fuel filler cap back and
tighten it securely.
