ANGLe TO THe CLeANING SurFACe
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 .
The optimum angle for spraying water against a cleaning
surface is 45 degrees .
Spray water against a surface at a 45 degree angle to achieve
the most beneficial impact force and to efficiently remove
debris .
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 nozzle’s fan pattern,
the nozzle’s angle to the cleaning surface, and the nozzle’s
distance from the cleaning surface . Never use a narrow high
impact stream or a Turbo/rotary nozzle on a surface that
is susceptible to damage . Avoid spraying windows with a
narrow high impact stream or turbo nozzle . Doing so may
break the window . The most sure way to avoid damaging
surfaces is to follow these steps:
1. Before triggering the gun, adjust the nozzle to a wide fan
pattern .
2 . Place the nozzle approximately 4-5 feet away from the
cleaning surface . Then hold the nozzle 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 .

TurBO LANCe (NOT INCLuDeD WITH ALL MODeLS)
A turbo lance is equipped with a permanently attached
nozzle . This nozzle, sometimes referred to as a rotary nozzle,
can significantly reduce cleaning time . The turbo nozzle
combines the power of a narrow high impact stream with the
efficiency of a 25 degree fan pattern . The turbo nozzle swirls
a narrow high impact stream into a cone shape to clean a
larger area .
since a turbo nozzle uses a narrow high
impact stream, only use a turbo lance in
applications where the cleaning surface cannot be damaged
by narrow high impact spray. The turbo nozzle is noT
adjustable and cannot be used to apply detergent.

NOTe:
Use only detergents formulated for pressure washers .
Test detergent in an inconspicuous area before use .
never slide the nozzle from low to
high pressure or from high to low
pressure when the gun is triggered.
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 ratio through the pump is approximately 12% (1 to
8) .
2 . Insert the filter end of the clear plastic detergent tube into
the detergent container .
3 . Place hand around the spraying end section of the lance
(the section that turns from left to right) . Pull firmly and
quickly away from you. (NOTE: Do not adjust lance while
spraying .) The lance will extend 1/2 inch and be in low
pressure (see Figure 13) . Soap can only be drawn in low
pressure .
