Pre-operation
ADJUSTING FAN PATTERN
The angle of spray 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 8)
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 carefully
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 and may 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.
Insert the cleaning needle (8) into the nozzle •
hole and move it back and forth until the debris
is dislodged (Fig 11).
Remove additional debris by backflushing water •
through the nozzle. To do this, place the end of
a garden hose (with water running) on the end
of the nozzle for 30-60 seconds.
