Operating Instructions and Parts Manual
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 dirt and grime. Use a brush to
lightly 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.
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.
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.
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.
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.
• Do not store the pressure washer
outdoors.
• Do not store the pressure washer
where it might freeze unless it has
been properly winterized.
LONG TERM STORAGE INSTRUCTIONS
(MORE THAN 30 DAYS IN STORAGE)
1. Remove fuel from the tank and run
the pressure washer in a normal
operating mode until the engine stops
from a lack of fuel. Normal operating
mode means actually spraying water
from the gun while 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.
