be used for washing, add liquid detergent. If the tank is to be used for making foam, fill it with fire-
extinguishing foam liquid.
Piping and Valves
Check that the piping, valves, clamps, and hose connections are properly fastened; tighten if necessary.
See that the pump drain valve is closed.
Throttle
See that the throttle is fastened to the engine accelerator linkage. See that the setscrew fastens the wire
of the throttle to the throttle bracket. Inspect the plastic knob for damage.
Fuel System
See that the fuel tank is securely mounted in the
frame. Check that the fuel line is tight and is not
leaking fuel. See that the wiring for the fuel
quantity transmitter and fuel gage is secure.
Check to see that the fuel tank is filled with gasoline
and that there is a one-inch void in the fuel tank. Be
sure the air cleaner is clean and serviceable. See
that the fuel tank cap fastens tightly and that the fuel
shut-off valve operates properly.
See that the fuel filter and sediment bowl are
serviced. If needed, clean the fuel filter and bowl as
follows:
Figure 17. Fuel filter and sediment bowl.
Step 1. Close the fuel valve on the fuel filter by
turning the handle clockwise. (Refer to Figure 17.)
Step 2. Unscrew the thumbscrew by turning it counterclockwise all the way. Move the bail to the right
or left side and remove the bowl.
Step 3. Unscrew the fuel strainer by turning it counterclockwise.
Step 4. Remove the gasket and inspect for cuts and tears. Replace bad gaskets.
Step 5. Clean the bowl with a clean rag and rinse with clean gasoline. Check the bowl for cracks and
chipped areas.
Step 6. Clean the fuel filter by using air pressure to blow out dirt.
Step 7. Screw the fuel filter onto the filler head by turning the fuel filter clockwise. Tighten the strainer
