WASHING WITH DETERGENT
See Figures 11 - 12.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact customer service or an authorized cus-
tomer 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.
 Disconnect pressure washer from power supply.
 Pour detergent in the soap tank. Use a funnel, if needed,
to prevent accidental spilling of the detergent outside
the tank. If any detergent is spilled during the filling
process, make sure the unit is cleaned and dried before
proceeding.
NOTE: The machine setting of this unit is 20:1, which
usually 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:
 Fill the soap tank with clean water.
 Spray the clear water through the spray wand until the
tank is empty.
 If any soap remains in the spray, repeat with a second
tank 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.
OPERATION
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 nozzle by placing hand over nozzle then
pulling back the quick-connect collar. Place soap nozzle
in the nozzle storage area on the machine.
 Select the right nozzle for the job. See the chart on the
previous page for selecting the appropriate nozzle.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
USING PUMP PROTECTOR
See Figure 13.
Regular use of a commercially available pump protector
prolongs the life of the pressure washer by removing hard
water mineral deposits, lubricating pump seals and pistons,
and preventing freeze damage. Pump protector should
be added to the unit after every use and before storage.
Pump protector can be purchased at the retailer where you
purchased your pressure washer, or by calling customer
service.
The instructions that follow are typical for adding pump
protector but you should always verify the specific
instructions provided by the manufacturer of the pump
protector used.
 Turn off the pressure washer motor, disconnect the power
supply, and shut off the water supply. Pull trigger to
release water pressure.
 Disconnect garden hose and high pressure hose.
 Unscrew threaded top from pump protector bottle and
remove paper seal from bottle. Reinstall top on bottle and
tighten securely.
NOTE: The rubber seal should remain inside the threaded
top. If it comes out, be sure to replace before reinstalling
the top.
 Remove bottle cap and attach threaded end of bottle
securely to pressure washer pump water intake.
 Squeeze bottle to inject contents into pump.
 Pump is protected when the protector fluid exits the pump
outlet.
