CLEANING FUEL CUP
See Figure 22.
n�Inspect fuel cup for water and dirt.
n�If dirt or water is present,CLOSE THE FUEL VALVE and remove the fuel cup. Using a wrench, grasp the square on the bottom of the fuel cup and turn clockwise.
n�After removing dirt and water, wash the fuel cup with kerosene or gasoline. Reinstall securely to prevent leak- age.
NOZZLE MAINTENANCE
See Figure 23.
Excessive pump pressure (a pulsing sensation felt while squeezing the trigger) may be the result of a clogged or dirty nozzle.
n�Turn off the pressure washer and shut off the water supply. Pull trigger to release water pressure.
n�Remove the nozzle from the spray wand. NOTE: Never point the spray wand at your face.
n�Using the nozzle cleaning tool provided with this prod- uct, free any foreign materials clogging or restricting the nozzle.
n�Using a garden hose, flush debris out of nozzle by back flushing (running the water through the nozzle backwards or from the outside to the inside).
n�Reinstall the nozzle then reconnect the nozzle to the spray wand.
n�Turn on the water supply and start the engine.
REPLACING THE FUEL HOSE
Replace the fuel hose every 1,000 hours of use. If fuel leaks from fuel hose, replace the hose immediately.
