•  Remove  additional  debris  by  back-flushing  water 

through the nozzle. To do this, place end of a garden 

hose ( with water running ) to end of nozzle for 30-60 

seconds.

ANGLE TO THE CLEANING SURFACE

When spraying water against a surface, maximum im-

pact is generated when the water strikes the surface 

“head on.” However, this type of impact tends to cause 

dirt particles to imbed in the surface, thereby preventing 

the desired cleaning action.

The optimum angle for spraying water against a cleaning 

surface if 45 degrees.

Figure 6 - Optimum angle to cleaning surface

Spraying water against a surface at this angle provides 

for  the  most  beneficial  impact  force  combined  with  ef

-

ficient removal of debris from the surface.

DISTANCE FROM CLEANLING SURFACE

Another factor that determines the impact force of the 

water is the distance from the spray nozzle to the clean-

ing surface. The impact force of the water is increased 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. 

The impact force can be varied by controlling the three 

previously noted items. Never use a narrow high im-

pact 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 as this may 

cause breakage.

The surest 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 from and 45 

degrees to the cleaning surface, and 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.

PRE-OPERATION

ADJUSTING FAN PATTERN

The angle of spray coming out of the lance may be ad-

justed on some lances by rotating the nozzle. This will 

vary the spray pattern from approximately a 0° narrow 

high impact stream to a 60° wide fan spray.

Figure 2 - Adjusting nozzle for fan pattern (not applica-

ble on some nozzle)

A narrow stream has high impact force on the cleaning 

surface and results in maximum deep cleaning in a con-

centrated area. However, this narrow high impact spray 

must be used cautiously, as it may damage some sur-

faces.

Figure 3 - Narrow high impact stream

A wide fan pattern will distribute the impact of the water 

over a larger area, resulting in excellent cleaning action 

with  a  reduced  risk  of  surface  damage,  Large  surface 

areas can be cleaned more quickly using a wide fan pat-

tern.

NOZZLE CLEANING INSTRUCTIONS

A clogged or partially clogged nozzle can cause a sig-

nificant reduction of water coming out of the nozzle and 

cause the unit to pulsate while spraying. To clean out the 

nozzle:

• Turn off and unplug unit.

•  Turn off water supply. Relieve any pressure trapped in 

the hose by squeezing trigger 2-3 times.

• Separate lance from gun.

•  Rotate nozzle to the narrow stream setting. This opens 

up the fan blades.

•  Using included tip cleaner, or an unfolded paper clip, 

insert wire into the nozzle hole and move back and forth 

until debris is dislodged. (See Figure 5.)
