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 Figure 2)

(not applicable on some nozzle)
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
spray must be used cautiously, as it may damage some
surfaces. (See Figure 3)
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.
(See Figure 4)

NOZZLE CLEANING INSTRUCTI-ONS
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:
f Turn off and unplug unit.
f Turn off water supply. Relieve any pressure trapped in
the hose by squeezing trigger 2-3 times.
f Separate lance from gun.
f Rotate nozzle to the narrow stream setting.
f This opens up the fan blades.
f 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.)

back and forth until debris is dislodged
f 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 imbed in the surface, thereby preventing the desired
cleaning action.
The optimum angle for spraying water against a cleaning
surface is 45 degrees.
Spraying water against a surface at this angle provides for
the most beneficial impact force combined with efficient
removal of debris from the surface.
