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. (
Fig 7
)
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.
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 the unit.
• Turn off the water supply and relieve
any pressure within the unit by
squeezing the trigger 2-3 times
• Separate the lance from the gun.
• Rotate the nozzle to the narrow stream
setting. This opens up the fan blades.
• Using the cleaning needle (12) or an
unfolded paper clip, insert the needle
into the nozzle hole and move it back
and forth until the debris is dislodged
(Fig 10).
• Remove additional debris by back-
flushing water through the nozzle.
To do this, place the end of a garden
hose (with water running) to the end of
the nozzle for 30-60 seconds.
Figure 7 – Adjusting nozzle for fan pattern
(not applicable on some nozzle)
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.

Low/High Pressure Adjustable Lance
High Pressure Setting:
Please make sure the trigger is released
and no water is coming out, then push
the spray nozzle in (Fig.11) to set to high
pressure.
Low pressure Setting:
Please make sure the trigger is released
and no water is coming out, then pull the
spray nozzle in (Fig.11) to set to low
pressure.
CAUTION:
Selection of high or low
pressure must be carried out with the
trigger off.

HOW TO AVOID DAMAGING
SURFACES
Damage to cleaning surfaces occurs
because the impact force of the water
exceeds the durability of the surface.
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 angled at 45 degrees
to the cleaning surface and begin
spraying.
3. Vary the fan pattern spray angle and
the distance to the cleaning surface
until optimum cleaning efficiency is
achieved without damaging the
surface.
