CARE AND MAINTENANCE
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.
• This system applies detergent under low pressure. 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 first 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 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 (not included) in small
hole at the end of the adapter. The screen filter will slide
out. Rinse it with clean water, then place it back in the
adapter.
