WARNING:
NEVER remove nozzles without first turning off the en-
gine, 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 in-
structions 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 sup-
ply. 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 sup-
ply. 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 pres-
sure 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 18 - 19.
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 a qualified service
center for more information.
NOTICE:
USE ONLY DETERGENTS DESIGNED FOR PRES-
SURE 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.
 Place the open end of the soap injection hose over the
barbed fitting on the pump.
 Place the filter end of the soap injection hose in the bot-
tom of the detergent bottle/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.
 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:
 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 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 sup-
ply. 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 and place in the nozzle storage
area.
 Select the right nozzle for the job. See the chart shown
earlier in the manual to select the appropriate nozzle.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
