STORAGE
• Do not store the pressure washer outdoors.
• Do not store the pressure washer where it might freeze unless
it has been properly winterized.
Winterizing Instructions
1. Disconnect the high pressure hose from the pump.
2. Insert a 12 inch to 14 inch piece of garden hose into the
pump inlet.
3. Place a funnel in the other end of the garden hose.
Read the manufacturer’s instructions for safe
handling and disposal of RV antifreeze.
4. Pour approximately 6 oz. of RV antifreeze into the funnel.
5. Jog the On/Off Switch briefly until the RV antifreeze comes
out of the pump outlet.
6. Disconnect the high pressure hose from the gun and drain
the hose. Hold the gun and lance in a vertical position and
squeeze the trigger to drain the water out.
NOZZLE CLEANING INSTRUCTIONS
A clogged or partially clogged nozzle can cause a significant
reduction of water coming out of the nozzle and cause the unit to
pulsate while spraying.
To clean out the nozzle:
• Turn off unit.
• Turn off water supply. Relieve any pressure trapped in the
hose by squeezing trigger 2-3 times.
• Separate lance from gun.
• Rotate nozzle to the narrow stream setting. This opens up the
fan blades.
• Using the included nozzle cleaner, or an un-folded paper clip,
insert wire into the nozzle hole and move back and forth until
debris is dislodged (refer to Figure 21).
• Remove additional debris by back-flushing water through
the nozzle. To do this, remove the lance from the gun, place
end of a garden hose (with water running) nozzle to nozzle
pushing water and debris out the back opening of the lance.
TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE
WASHER
1. Never operate the unit without water.
2. Your pressure washer is not meant to pump hot water. Never
connect your pressure washer to a hot water supply as it will
significantly reduce the life of the pump.
