• 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. (figure 3.)
• 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
(fig 4)
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.
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.

PRE-OPERATION
ADJUSTING FAN PATTERN
Water can be sprayed with a narrow stream or fanlike.

. Install the required nozzle before
starting work, depending on the task (fig 2).
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.
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.
