HOW TO USE THE
DETERGENT INJECTOR
WARNING: Some detergents may
be harmful if inhaled or ingested
causing severe nausea, fainting
or poisoning. The harmful ele-
ments may cause property dam-
age or severe injury.
The machine can siphon and mix de-
tergents with the use of Shark's de-
tergent injector kit.
1. Pull injector quick coupler collar back and secure on
discharge nipple. Injector valve body arrow should
point in direction of flow.
2. Connect high pressure hose to injector nipple se-
curing quick coupler.
3. Start machine as outlined in Operating Instructions.
4. Place detergent pick-up tube into container of deter-
gent solution.
5. Turn pressure control handle counterclockwise on
the variable pressure wand. This lowers the pres-
sure by directing the water flow through the soap
nozzle and allows the detergent injector to siphon
soap.
6. Open trigger spray gun. Water detergent ratio is
approximately 15 to 1.
7. When you finish washing, rinse by simply turning
the variable pressure wand control handle clockwise
to increase pressure.
NOTE:
The detergent injector will not siphon with
water flowing through the high pressure nozzle at
the end of the wand.
8. For clean up, place detergent pick-up tube into con-
tainer of clear water and follow steps 5 and 8 to pre-
vent detergent deposits from damaging the injector.
