USING THE HIGH PRESSURE HOSE
WARNING:
Injection hazard. Fully unwrap and straighten high
pressure hose prior to and during each use and do
not allow it to become kinked. The high pressure hose
features an outer covering that provides strength to the
hose. If the outer covering becomes damaged, stop using
the hose and replace it immediately. A kinked or damaged
hose can develop a high pressure leak and result in a
possible injection or other serious personal injury.
To prevent damage to the outer covering:
 Inspect the hose before every use.
 Fully unwrap and straighten hose before use.
 Do not allow the high pressure hose to be kinked.
 Keep hose away from hot surfaces and sharp edges.
 Do not pull unit by high pressure hose.
 Do not allow hose to be crushed or wrapped around
objects.
WASHING WITH DETERGENT
See Figures 12 - 13.
As sold, this unit is designed for use with "downstream"
pressure washer detergents. To convert for use with
"upstream" detergents, contact customer service or an
authorized customer service center for more information.
NOTICE:
USE ONLY DETERGENTS DESIGNED FOR PRESSURE
WASHERS. Do not use household detergents, acids,
alkalines, bleaches, solvents, flammable material, or
industrial grade solutions, which can damage the pump
or cause property damage. 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.
OPERATION
 Disconnect pressure washer from power supply.
 Place one end of the soap injection hose over the barbed
fitting on the pump.
 Remove the cap from the soap container and place the
soap injection hose with filter in the 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 the blue or black soap nozzle on the spray wand.
 Connect unit to power supply and turn the pressure
washer on.
 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.
Before shutting off the motor:
 Place the soap injection hose with filter in a bucket of
clean water.
 Spray the clear water through the spray wand until the
bucket is empty.
 If any detergent remains in the spray, repeat with a second
bucket of clean water.
 Shut off the motor.
NOTE: Shutting off the motor will not relieve pressure in the
system. Pull trigger to release water pressure.
RINSING WITH THE PRESSURE WASHER
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Remove the soap injection hose, if installed.
 Remove the soap nozzle by placing hand over nozzle then
pulling back the quick-connect collar. Place soap nozzle
