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)
Figure 2 - Adjusting nozzle for fan pattern
( 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.
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.)
Figure 5- Insert tip cleaner in nozzle hole and move back and
forth until debris is dislodged
• 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 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
if 45 degrees.
