When spraying water against a surface, you can
generate maximum impact by striking the surface
head on. However, this type of impact can cause
dirt particles to embed in the surface and can
prevent the desired cleaning action.
Spray water against a surface at a 45 degree angle
to achieve the most beneficial impact force and to
efficiently remove debris.
Figure 15 - Optimum angle to 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


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 tip angle to the cleaning
surface and the distance from the cleaning surface
and by changing the spray tip. 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 tip you are using is appropriate for the
The color of the tip shows what spray angle it is:
Red – 0° – Maximum Duty
Yellow – 15° – Heavy Duty
Green – 25° – General Duty
White – 40° – Light Duty
Black – 65° – Low Pressure Detergent
2. Place the spray tip approximately 4-5 feet (1,22-
1,52 m) away from the cleaning surface. Then
hold the lance and spray tip at a 45 degree
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.

4. Detergent Application

NOTE: Use only detergents formulated for pressure
NOTE: Test detergent in an inconspicuous area
before use.


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.

when gun is triggered.
