Pre-operation
Adjusting fan pattern
The angle of spray coming out of the lance
may be adjusted 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.
(See Figure2)
A narrow stream has high impact force on the
cleaning surface and results in maximum deep
cleaning in a concentrated area. However, this narrow
high impact pray must be used cautiously, as it may
damage some surfaces.
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 pattern.

Nozzle cleaning instructions
A clogged or partially clogged nozzle can cause a
significant 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.)

and move back and forth until debris is dis-
lodged
• Remove additional debris by back-flushing water
through the nozzle. To do this, place end of a garden
hose ( with water running ) to the end of nozzle for 30-
60 seconds.
Angle to the cleaning surface
When spraying water against a surface, maximum
impact is generated when the water strikes the
surface “head on.” However, this type of impact tends
to cause dirt particles to embed in the surface,
thereby preventing the desired cleaning action.
The optimum angle for spraying water against a
cleaning surface is 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 efficient removal of debris from the
surface.
Distance from cleaning surface
Another factor that determines the impact force of the
water is the distance from the spray nozzle to the
cleaning 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 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 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.
