WARNING:
NEVER remove nozzles without first turning off the
engine, relieving the water pressure in the trigger
handle, and locking the lock out on the trigger handle.
NEVER point the nozzle at your face or at others. The
quick-connect feature contains small springs that could
eject the nozzle with some force. Failure to follow these
instructions could result in an eye injury or other serious
personal injury.
To connect a nozzle to the spray wand:
 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.
 Pull back the quick-connect collar.
 Push the nozzle into place in the spray wand.
 Push the collar forward so that the nozzle is secured
properly. Check to see that the nozzle is secure.
To disconnect a nozzle from the spray wand once the
cleaning job is complete:
 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.
 Pull back and hold the quick-connect collar.
 Remove the nozzle by pulling it from the quick-connect
collar. Place nozzle in the nozzle storage area on the top
of the machine.
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.
OPERATION
WASHING WITH DETERGENT
See Figures 15 - 16.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact an customer service or a qualified 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.
 Remove the cap from the soap tank and pour pressure
washer detergent in the tank. Replace cap on tank.
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 soap nozzle on the spray wand.
 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 engine:
 Fill the soap tank with clean water.
 Spray the clear water through the spray wand until the
tank is empty.
 If any detergent remains in the spray, repeat with a second
tank of clean water.
 Shut off the engine.
NOTE: Shutting off the engine 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 nozzle by placing hand over nozzle
then pulling back the quick-connect collar. Place nozzle
in the nozzle storage area on the top of 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.
