SPRAY TIP MAINTENANCE
Excessive pump pressure (a pulsing sensation felt while squeezing the trigger) may be the result of a
clogged or dirty spray tip.
Unplug the pressure washer.
Turn off the pressure washer and shut off the water supply. Pull trigger to release water pressure.
Remove the spray tip from the spray wand.
NOTE: Never point the spray wand at your face.
Using the spray tip cleaning tool provided, free any foreign materials clogging or restricting the spray tip
opening. Refer to Fig. 12
Using a garden hose, flush debris out of the spray tip by back flushing (running the water through the
spray tip backwards or from the outside to the inside).
Reconnect the spray tip to the spray wand.
Turn on the water supply.
STORING THE PRESSURE WASHER
Store in a dry, covered area where the weather can't damage it. It is important to store this product in
a frost-free area. Always empty water from all hoses, the pump, and the detergent container before
storing.
NOTE: Use of a pump saver will give you better performance and increase the life of the machine.
