Operation (Continued)
Distance From Cleaning Surface
The distance between the spray nozzle and the cleaning surface
is another factor that affects the impact force of the water. The
impact force of the water increases as the nozzle is moved
closer to the surface.
How to Avoid Damaging Surfaces
Damage to cleaning surfaces occurs because the impact force
of the water exceeds the durability of the surface. You can vary
the impact force by controlling the spray nozzle angle to the
cleaning surface and the distance from the cleaning surface
and by changing the spray nozzle. NEVER use a narrow high
impact stream on a surface that is susceptible to damage. Avoid
spraying windows with a narrow high impact stream. Doing so
may break the window. The most sure way to avoid damaging
surfaces is to follow these steps:
1. Before triggering the gun, make sure the quick connect
nozzle you are using is appropriate for the application.
2. Place the spray nozzle approximately 4-5 feet (1,22-1,52 m)
away from the cleaning surface. Then hold the lance and
spray nozzle at a 45° angle to the cleaning surface. Trigger
the gun.
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 top and work your way down. 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 nozzle.
General Cleaning Nozzles
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 nozzle with another high
pressure color nozzle.
before removing or installing quick connect nozzles.
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 nozzle.

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 also have a pressure adjustment knob on
the pump that can adjust the pressure.

FINAL RINSE

The final rinse should start at the top and work downward. 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.
