CARE AND MAINTENANCE
• NEVER use a narrow high pressure stream of water on soft surfaces susceptible to damage.
• Use the variable spray nozzle when cleaning windows. Be sure to adjust the nozzle to low spray
and place the nozzle approximately four to ve feet away from the window with the nozzle at forty
ve degree angle. Squeeze the trigger and vary the spray pattern and angle until optimum cleaning
efciency is achieved.
Detergents
• Use detergents designed for power washers. Hardware stores or home centers also have power
washer detergents for different cleaning projects. The cleaning solution should be the consistency of
water in order to prevent clogging your detergent bottle and nozzle.
• The cleaning power of the detergents is enhanced when applied with low pressure and enough
time is given to break down dirt and grime. The combination of low pressure and chemical action
is very effective and can be better than scrubbing if applied properly. Always spray detergent on a
dry surface. Do not pre-soak area. Wetting the surface rst dilutes the detergent and reduces its
cleaning ability. Do not allow detergent to dry on surface. On vertical surfaces being cleaned, apply
detergent to lower surfaces and work your way up to prevent detergent from causing streaks in the
dirt and grime. Rinse detergent by pressure washing from bottom up for same reason.
• If a stain is particularly tough, it may be necessary to reapply the detergent and use a bristled brush
to scrub the stain. Subsequent power washing after brushing should successfully complete your
cleaning job.
Cleaning Nozzles
• A clogged or partially clogged nozzle can cause signicant 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 (not
included) in small hole at the end of the adapter. The
screen lter will slide out. Rinse it with clean water, then
place it back in the adapter.
