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.
