HO W TO USE THE
DETERGENT INJECTOR
WARNING
SOME DETERGENTS
MAY BE HARMFUL
IF INHALED OR
INGESTED
1. Turn engine and water supply off. Squeeze spray
gun to relieve pressure before attaching detergent
injector.
2. T o attach detergent injector between pressure washer
and high pressure hose, pull injector quick coupler collar back and secure on discharge nipple. Injector valve
body arrow should point in direction of flow .
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting
or poisoning. The harmful elements may cause property damage or severe injury .
The machine can siphon and mix
detergents with the use of Shark's
detergent injector kit.
3. Connect pressure discharge hose to injector nipple
securing quick coupler by pushing collar towards
nipple.
4. Start machine as outlined in Operating Instructions.
5. Place detergent pickup tube into container of detergent solution.
6. Insert soap nozzle into quick coupler.
7. Open spray gun. Water detergent ratio is approximately 15 to 1.
8. For clean up , place detergent pic kup tube into container of clear water and follow steps 5 to 7 to prevent detergent deposits from damaging the injector .
9. If your machine has a variable pressure wand, to
wash, turn the pressure control handle counterclockwise to lower the pressure. This directs the water
flow through the soap nozzle and allows the detergent injector to siphon soap. T o rinse with high pressure water, simply turn the control handle clockwise.
NOTE: The detergent injector will not siphon detergent with high pressure.
