Operation (Continued)
3. Vary the fan pattern spray angle and the distance to the
cleaning surface until optimum cleaning efficiency is
achieved without damaging the surface.
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
ratios 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.
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.

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 may have also a pressure adjustment knob on
the pump that can adjust the pressure.
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.
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 ignition cable from
the spark plug.
7. Before overnight storage, long term storage, or transporting
unit, disconnect the water supply and turn off the fuel supply
valve.
SHUTDOWN
1. Be sure all detergent is flushed from system.
2. Turn the engine OFF.
3 Turn the water supply OFF.
4. After the motor 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.
