OPERATING INSTRUCTIONS
Adjusting Soap Levels on Foam
Cannon
Twist knob to adjust the level of soap as
indicated on the top of the Foam Cannon
(D). Twist toward the higher concentration
of bubbles for more soap, or the opposite
direction for less.
Always test a small area to avoid chance of
damaging the surface.
The machine comes with 4-in-1 nozzle. The
nozzles are 0°, 20°, 60° and rotating turbo
nozzle. To change between nozzles, turn
clockwise. To remove the 4-in-1 nozzle from
the lance, turn counter clockwise and it will
detach.
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. You can vary the force of your
power cleaner by controlling:
1. The angle of the surface being cleaned.
2. The distance of the nozzle from the surface
being cleaned.
Never use a narrow high pressure stream of
water on soft surfaces susceptible to damage.

CARE AND MAINTENANCE
Detergents
Use detergents designed for power cleaners.
Hardware stores or home centers also
have power cleaner 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, then lock the
gun by pressing the button to lock position.
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.
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).

Storage
When your cleaning session has been
completed. Turn off the water supply. Pull
the trigger on the spray gun 2-3 seconds to
drain out the excess water and to release any
remaining water pressure. Do not allow the
power cleaner to run with no water flowing
through it.
Remove lance from the gun. Store all in the
package.
Make sure to discard any remaining detergent
from the tank. Residual chemical will stick
to the container which could become
contaminated, and can cause the detergent
injector to clog and not function properly.
Flush the tank and nozzle head with clear
water to prevent clogging.
Remove the battery pack.
DO NOT store the power cleaner where
it is exposed to freezing temperatures.
Store the power cleaner indoors to prevent
the water in the unit from expanding under
freezing conditions. When the water freezes
and expands, your power cleaner will be
damaged and become inoperable.
