Cleaning with Detergents
All units are equipped with a chemical injection kit.
Locate the clear vinyl hose that is shipped with your unit.
NOTE:
This injection system is designed to apply
detergents under low pressure only. It will not allow
detergent solutions to be introduced into the system
unless the chemical/detergent nozzle is used.
1. Perform
Pressure Relief Procedure
, page 10.
2. Install chemical injector hose between the pump
outlet and the high-pressure washer hose inlet. For
washers shipped with an integrated chemical
injector, attach the clear chemical injection tube to
the barb on the injector.
3. Adjust pressure to the lowest point by turning the
pressure knob counterclockwise on the unloader
valve.
4. Immerse detergent strainer into detergent solution
to allow detergent to siphon.
5. Engage trigger lock and secure the
chemical/detergent nozzle (65° BLACK) into end of
wand. See
6. Start the washer. See
14.
7. 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
bottom up helps to avoid streaking. Allow to soak
briefly. Do not allow detergent solution to dry on the
surface. Avoid working on hot surfaces or in direct
sunlight to minimize the chances of the detergent
drying, which may result in damaging painted
surfaces. Rinse a small section at a time.
8. To rinse; engage trigger lock and securely connect
desired high pressure nozzle into end of wand.
Disengage 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. See
9. Siphon a gallon of water through low pressure
detergent injection system after each use. This
reduces the possibility of corrosion or detergent
residue causing mechanical problems during next
use.

2. Once pressure is relieved, disconnect nozzle
assembly.
3. Disconnect and drain gun, wand and hose.
4. Wipe unit clean and store with gun, wand and hoses
in a non-freezing area. See
