4. DETERGENT APPLICATION
NOTE:Useonlydetergentsformulated
for pressure washers.Test detergent in an
inconspicuous area before use.
DETERGENTS
The use of detergents can dramatically
reduce cleaning time and assist in
the removal of difficult stains. Many
detergents are customized for pressure
washer use on specific cleaning tasks.
Pressure washer detergents are as thick as
water.Usingthickerdetergents–likedish
soap – will clog the chemical injection
system and prevent the application of the
detergent.
Once applied to a cleaning surface,
detergents take time to break down dirt
and grime. Detergents work best when
applied at low pressure.
You can effectively clean surfaces by
combining the chemical action of
detergents with high pressure rinses. On
vertical surfaces, apply the detergent
starting at the bottom and work your
way upward. This method prevents the
detergent from sliding down and causing
streaks. Begin high pressure rinsing at the
bottom and work your way upward. On
particularly tough stains, use a brush in
combination with detergents and high
pressure rinsing.
1. Follow manufacturer’s label directions
formixingcorrectconcentrationsof
soap/detergents. The soap detergent
to water ration through the pump is
approximately10%(1to10).
2. Insert the filter end of the clear plastic
detergent tube into the detergent
container.
3. UsetheBLACK 65° quick connect
spray tip.
4. Adjust the detergent injection flow
by turning the collar of the injector.
Turning collar clockwise increases
detergent flow.
GENERAL CLEANING TIPS
1. Apply the detergent so that it
thoroughly covers the cleaning
surface. Apply the detergent from
bottom to top to prevent the
detergent from sliding down and
streaking. Wait a couple of minutes
for the detergent to break down the

scrub heavily soiled areas. NEVER
allow the detergent to dry on the
cleaning surface.
2. To rinse: replace black 65° spray tip
with another color tip.
NEVER replace
quick connect tip
when gun is triggered. Always engage
trigger lock on gun before removing or
installing quick connect tips.
3. After using detergents, flush the
suction system by placing the
detergent suction tube into a bucket
of clean water and spraying with the
black spray tip.
5. CLEANING POWER
The easiest way to regulate the cleaning
power of your pressure washer is by
changing the distance from the surface
you are cleaning. Begin spraying with a
wide fan pattern while standing several
feet from the surface. Slowly move closer
to the object you are cleaning, adjusting
the spray pattern as necessary, until
you find the most effective cleaning
technique.
NOTE: The unit also has a pressure
adjustment knob on the pump that can
adjust the pressure.
6. FINAL RINSE
The final rinse should start at the bottom
and work upward. Make sure that you
thoroughly rinse the surface and that you
remove all detergent.
7. PRESSURE RELIEF PROCEDURE
To reduce the risk of bodily injury or
property damage, always follow this
procedure whenever spraying is stopped,
when work is completed, and before
checking or repairing any part of the
system.
1. Engage the trigger safety latch.
2. Turn the unit off.
3. Shut off the water supply.
4. Disengage the trigger safety latch and
trigger the gun to relieve pressure.
5. Re-engage the trigger safety latch.
6. When checking or repairing unit,
remove the ignition cable from the
spark plug.
Operation (Continued)
7. Before overnight storage, long
term storage, or transporting unit,
disconnect the water supply and turn
off the fuel supply valve.
8. SHUTDOWN
1. Be sure all detergent is flushed from
system.
2. Turn the engine OFF.
3 Turn the water supply OFF.
4. After the engine and water supply
are turned off, trigger the gun to
depressurize the system.
NEVER turn the
water supply off
before turning the engine/motor off.
Serious damage could occur to the pump
and/or engine/motor.
NEVER disconnect
the high pressure
discharge hose from the machine
while the system is pressurized. To
depressurize, turn engine/motor off, turn
water supply off and squeeze gun trigger
2-3 times.
5. After each use, wipe all surfaces of
the pressure washer with a clean,
damp cloth.

LONG TERM STORAGE INSTRUCTIONS
(MORE THAN 30 DAYS IN STORAGE)

the pressure washer in a normal
operating mode until the engine
stops from a lack of fuel. Normal
operating mode means actually

the engine is running.
Alternate method – Add fuel
stabilizer to gas in the tank and run
in normal operating mode for at least
five minutes.
2. Stop the engine, turn off the water
supply, and trigger the gun to release
pressure in the high-pressure hose.
3. Disconnect the water supply and high
pressure hose from the pump.
4. Allow the engine to cool.
