WASHING WITH DETERGENT
See Figure 16.
As sold, this unit is designed for use with “downstream”
pressure 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. Do not use household detergents, acids, alka-
lines, bleaches, solvents, flammable material, or industrial
grade solutions, which can damage the pump. Many de-
tergents 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 detergent injection hose in the bottom of the
detergent bottle / container.
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:

Place the detergent injection hose in a bucket of clean
water.
 Spray the clear water through the spray wand until the
bucket is empty.
 If any soap 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
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 nozzle by placing hand over nozzle then
pulling back the quick-connect collar. Place 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.
MOVING THE PRESSURE WASHER
See Figure 17.
NOTE: Never lift or carry this product using the handle.

Turn the pressure washer off.
 Tilt the machine toward you slightly until it balances on
the wheels then roll the machine to the desired position.
Do not tilt forward or sideways when moving.
 DO NOT attempt to move the unit by pulling on any of
the hoses.
HIGH ALTITUDE OPERATION
Specific modifications are needed for high-altitude op-
eration for equipment operating in altitudes greater than
3000 feet above sea level. Please contact your authorized
service center for important information regarding these
modifications. Operating this engine without the proper
altitude modification may increase the engine’s emissions
and decrease fuel economy and performance.
