WASHING WITH DETERGENT
See Figure 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.
 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 1:20, which
usually allows the use of 1 gallon detergent without further
dilution. Check your detergent instructions to be sure
additional dilution is not necessary.
 Install the black nozzle on the spray wand.
 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 injection hose
then slide the hose out of the cap. Place the injection hose
filter back on the hose and place the hose in the bottom of
the bottle.
For detergent application:
With the black nozzle installed on the spray wand and the
engine turned off, submerge the hose and black filter down
into the detergent container as far as it will go.
Before shutting off the engine:
 Place the 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
