Care and Maintenance
Detergents
• Use detergents designed for power washers. Hardware
stores or home centers may offer detergents for
different cleaning projects. The cleaning solution
should be the consistency of water in order to prevent
detergent bottle and spray tip from clogging.
• This system applies detergent under low pressure using
the black spray tip only. The cleaning power of the
detergent is enhanced when applied with low pressure
and enough time is given to break down dirt and grime.
• When finished applying detergent, remove excess
detergent from the on board tank and run one tank of
clear water using the low pressure black spray tip to
thoroughly clean all excess detergent out.
• Remove and clean the detergent filter on the siphon
tube to avoid detergent from caking and clogging the
filter.
• 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, apply detergent to lower surfaces first and
work your way up to prevent streaks in the dirt and
grime. Rinse detergent by pressure washing from
bottom up for same reason.
• For tough stains, it may be necessary to reapply the
detergent and use a bristled brush to scrub the stain.
Subsequent power washing after brushing should
successfully remove dirt.
Cleaning Garden Hose Adapter
The screens inside the garden hose adapter should be
cleaned periodically.
1. Rinse with clean water.
2. Place back into the adapter.
Cleaning Spray Tips
A clogged spray tip can significantly reduce water
pressure and/or cause the unit to pulsate while spraying.
1. Turn off the unit and the water supply.
2. Relieve any pressure trapped in the hose by squeezing
the trigger 2-3 times, then lock the spray gun.
3. ALWAYS remove spray tips before cleaning.
4. Using the spray tip cleaner provided, insert the wire
into the spray tip hole and slide back and forth until
debris is dislodged.
5. Back flush water through the spray tip using a garden
hose and highest pressure available (hold thumb over
water nozzle to increase pressure).
