Cleaning with Detergents
Some units are equipped with adjustable detergent
knobs. Locate the clear vinyl hose which leads to the
pump head.
If injector is equipped with adjustment knob on pump
head, detergent amount can be adjusted by turning the
knob completely counter-clockwise to set at maximum
siphon rate.
If injector is not equipped with an adjustment knob,
detergent ratio is preset and cannot be adjusted.
1. Immerse detergent strainer into detergent solution
to allow detergent to siphon.
2. Engage trigger lock and secure quick-connect
detergent spray nozzle (#6540° BLACK) into end of
wand.
NOTE: This injection system is designed to apply deter-
gents under low pressure only. It will not allow detergent
solutions to be introduced into the system unless the
nozzle assembly is in the low pressure detergent mode.
3. To apply solution; disengage trigger lock and
squeeze trigger. A detergent/water mixture will exit
low pressure nozzle. Start spraying lower portion of
surface being cleaned and move up, using long
overlapping strokes. NOTE: Applying from the bot-
tom up helps avoid streaking. Allow to soak briefly.
Do not allow detergent solution to dry on the sur-
face. Avoid working on hot surfaces or in direct sun-
light to minimize the chances of the detergent
drying, which may result in damaging painted sur-
faces. Rinse a small section at a time.
4. To rinse; engage trigger lock and securely connect
desired high pressure nozzle into end of wand. Dis-
engage trigger lock and spray. It will take about 30
seconds to purge all detergent from line. For best
rinsing results, start at the top and work down.
5. Siphon a gallon of water through low pressure
detergent injection system after each use. This
reduces the possibility of corrosion or detergent res-
idue causing mechanical problems during next use.
Shutdown
1. Turn engine “OFF” (see engine manual).
2. Turn water supply “OFF”.
3. Point gun in a safe direction and trigger gun to
relieve any trapped pressure.
4. Once pressure is relieved, disconnect nozzle
assembly.
5. Disconnect and drain gun, wand and hose.
6. Wipe unit clean and store with gun, wand and hoses
in a non-freezing area.
BURN OR EXPLOSION HAZARD
Always wear protective safety attire.
Prepare detergent solution according to label direc-
tions. Never pump
hazardous detergents or acid-type
cleaners through unit.
