Cleaning nozzles

• A clogged or partially clogged nozzle can cause significant reduction of water
pressure coming out of the nozzle and/or cause the unit to pulsate while
spraying.
• Turn off the unit
• Turn off the water supply to the unit
• Relieve any pressure trapped in the hose by squeezing the trigger 2-3 times,
and then lock the spray gun by pushing the lock button from left to right.
• The screen inside the clear adapter should be cleaned periodically. Insert a pen
or pencil in small hole at the end of the adapter. The screen filter will slide out
(Fig. 19). Rinse it with clean water, and then place it back in the adapter.
• Using the nozzle tip cleaner provided (or an unfolded paper clip), insert the wire
into the nozzle hole and move back and forth until debris is dislodged (Fig. 20).
Back flush water through the nozzles using garden hose and highest pressure
available (either standard water nozzle or use your thumb over the nozzle to
create water pressure for back flush).

OPERATING TIPS AND MAINTENANCE

• If you hear the motor run intermittently when the trigger is not being squeezed,
that is normal. The pump is priming itself so it is ready to operate when the
trigger is squeezed. Turn off the power washer if not being used after five
minutes.
• The o-rings on the bayonet end of the adjustable lance should be cleaned
regularly and lubricated with non-water soluble grease such as petroleum jelly.
• Keep the nozzle cleaning wire, which is taped to this manual, for use in
unclogging the lance nozzle. If you lose the cleaning wire an unbent paper clip
works fine.
• NOTICE: Always make sure the water inlet line (garden hose) is not kinked
or restricted from providing sufficient water flow. Insufficient water flow may
damage the pressure washer pump.

How to Avoid Damaging Surfaces

• Damage to surfaces being cleaned occurs because the impact force of the water
pressure exceeds the durability of the surface. Bare wood can be penetrated;
paint can be peeled off, etc.
