SHUT DOWN PROCEDURES
1. Rinse all lines (and injector) with clean water, to re-
move any soap residue.
2. Turn engine off.
3. Turn off water supply.
4. Open spray gun to relieve remaining pressure.
5. Remove water supply hose.
6. In freezing conditions, disconnect water supply and open
spray gun to allow water to drain, then turn off motor.
CAUTION: Do not allow pump to run longer than 5
minutes without water. Disconnect all hoses to al-
low water to drain. With machine off, open spray gun
to release pressure before removing discharge hose.
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 Landa'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. Install the brass soap nozzle provided with the in-
jector into the quick coupler of the wand. Models with
a variable pressure wand have this nozzle built into
the wand.
6. Pull trigger on spray gun. Water detergent ratio is
approximately 15 to 1.
7. When you finish washing, rinse by simply releasing
the trigger on the spray gun, removing the soap
nozzle, and replacing the pressure nozzle back into
quick coupler.
NOTE: The detergent injector will not siphon with
the high pressure nozzle at the end of the wand.
8. If your machine has a variable pressure wand, turn
the pressure control handle counterclockwise to
lower the pressure by directing the water flow through
the soap nozzle. This allows the detergent injector
to siphon soap. To rinse with high pressure water,
simply turn the control handle clockwise.
9. 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.
