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 Fig 13)
A narrow stream has high impact force on 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.
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 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 (16) or an unfolded •
paper clip, insert the needle into the nozzle hole
and move it back and forth until the debris is
dislodged (Fig 16)
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.
