WASHING WITH DETERGENT
See Figure 17 - 19.
As sold, this unit is designed for use with “downstream” pres-
sure washer detergents. To convert for use with “upstream”
detergents, contact an authorized customer service center
for more information.
Use only detergents designed for pressure washers; house-
hold detergents, acids, alkalines, bleaches, solvents, flam-
mable material, or industrial grade solutions can damage
the pump. Many detergents may require mixing prior to use.
Prepare cleaning solution as instructed on the solution bottle.
Always test in an inconspicuous area before beginning.

Remove the cap from the detergent container and pour
detergent in the container. Replace cap on container.
NOTE:
The machine setting of this unit is 20:1, which usu-
ally allows the use of 1 gallon pressure washer detergent
without further dilution. Check your detergent instructions
to be sure additional dilution is not necessary.

Install 6-in-1 Change-Over Nozzle (if necessary). Rotate
the spray selector on the nozzle to either the short range
detergent ( ) or long range detergent ( ) setting.

Squeeze the trigger and wait approximately 5 seconds
for the detergent to appear.

Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
NOTE:
To use a detergent bottle, open the detergent container
cap. Next, remove the filter from the end of the detergent
injection hose then slide the hose out of the cap. Place the
detergent injection hose filter back on the hose and place
the hose in the bottom of the bottle.
For long range detergent application:
With the nozzle installed on the spray wand and the engine
shut off, rotate the spray selector to the long range detergent
[ ] setting.
For short range detergent application:
With the nozzle installed on the spray wand and the engine
shut off, rotate the spray selector to the short range deter-
gent [ ] setting.
Before shutting off the engine:

Place the detergent injection hose in a bucket of clean
water.

Flush for 1 - 2 minutes (spray clear water through the
spray wand).

Shut off the engine.
NOTE: Shutting OFF ( O ) the engine will not relieve pressure
in the system. Pull trigger to release water pressure.
RINSING WITH THE PRESSURE WASHER
