System Connection
1. Insert lance into the gun and turn clockwise to positive
stop as shown in Figure 3.
2. Attach the high pressure hose onto the gun by turning
clockwise and tighten with a wrench.
3. Be sure that the power switch is in the
“OFF”
position.
4. Attach the high pressure hose onto the pump water
outlet by turning clockwise and hand tightening.
5. Connect garden hose as explained under Garden Hose
Connection Instructions.
6. Plug the power cord into a grounded 120 V outlet.
7. Turn water on.
8. Unlock trigger lock by moving lock right to left.
9. Depress and hold the trigger on the gun for one minute
to release pressure and remove any air trapped in the
system.
10. Turn the
“ON / OFF”
switch to the
“ON”
position.
How to Avoid Damaging Surfaces
DIRECTIONS FOR USE
Damage to cleaning surfaces occurs because the impact
force of the water exceeds the durability of the surface.
You can vary the impact force by controlling the nozzle’s
fan pattern, the nozzle’s angle to the cleaning surface, and
the nozzle’s distance from the cleaning surface. Never use a
narrow high impact stream or a turbo nozzle on a surface
that is susceptible to damage. Avoid spraying windows with
a narrow high impact stream or turbo nozzle. Doing so
may break the window. 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 away from the
cleaning surface. Then hold the nozzle at a 45° angle to
the cleaning surface. Trigger the gun.
3. Vary the fan pattern spray angle and the distance to the
cleaning surface until optimum cleaning efficiency is
achieved without damaging the surface.
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 unit.
• Turn off water supply. Relieve any pressure trapped in
the hose by squeezing trigger 2-3 times.
• Separate lance from gun.
• Rotate nozzle to the narrow stream setting. This opens
up the fan blades.
• Using the included tip cleaner, or an un-folded paper
clip, insert wire into the nozzle hole and move back and
forth until debris is dislodged (refer to Figure 4).
• Remove additional debris by back-flushing water
through the nozzle. To do this, remove the lance
from the gun, place end of a garden hose (with water
running) to tip of nozzle pushing water and debris out
the back opening of the lance.
