HOW TO USE THE
DETERGENT INJECTOR
WARNING: Some detergents
may be harmful if inhaled or in-
gested causing severe nausea,
fainting or poisoning. The harm-
ful elements may cause property
damage or severe injury.
The machine can siphon and
mix detergents with the use of
Karcher's detergent 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
detergent 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 clock-
wise 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
container of clear water and follow steps 5 and 8
to prevent detergent deposits from damaging the
injector.
