Adjusting the Spray Fan Angle
1. The lance is affected by pressure during operation; therefore
hold it firmly with both hands and point the nozzle toward the
ground.
2. Activate by pulling
the trigger of the
gun/spray handle.
3. Adjust
the
distance
to the cleaning
surface, which will
also adjust your
pressure of the
nozzle.
4. Spray pattern
shape and
intensity can
be changed by
twisting the spray
adjuster at the
end of the lance
(see Figure 21).
Keep hands clear
of the front of the
lance to prevent
injury.
Pressure can also
be adjusted by
moving closer or
further away from
the cleaning surface
and by adjusting the
spray fan angle as
shown.
Angle to the Cleaning
Surface
When spraying water
against a surface,
you can generate
maximum impact by
striking the surface
head on. However,
this type of impact
can cause dirt
particles to embed in
the surface and can
prevent the desired
cleaning action.
The optimum angle
for spraying water
against a cleaning
surface is 45
degrees. (Figure 22)

pump and hose. Make sure to connect pump side of adapter
to pump water inlet to prevent damage to the threads.
3. Attach a garden hose to the inlet side of the pump and
connect it to the water supply. Use a hose with an internal
diameter (I.D.) of 5/8 in. (1.58 cm) and a length of 50 ft. (15 m)
or less.
Some local plumbing codes require backfl ow
prevention when connecting to a fresh water supply. Install a backfl ow
preventer upstream from the pump if necessary.
a. If inlet water pressure is over 100 psi, install a regulating
water valve at the garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of
5 gpm (19 lpm).
4. Turn the water supply ON.
Never run the unit dry. Be sure the water supply is
completely turned on before operating the unit.
5. Trigger the gun until water sprays from the nozzle indicating
that all air is purged from the system. Set the trigger safety
latch.
6.
Plug the power cord into a grounded 120V outlet, that is on
a dedicated circuit. Press the reset button on the GFCI plug
adapter. This must be done each time the unit is plugged into
an outlet. (Figure 18)
SYSTEM CONNECTION
1. Insert lance into the gun and turn clockwise to connect as
shown in Figure 19.
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 120V outlet.
7. Turn water on.
8. Unlock trigger lock by moving lock right to left. (Figure 17)
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.
INITIAL HIGH PRESSURE RINSE
Spray the cleaning surface with water to clear off any dirt or
grime that may have collected on the surface. Doing so allows
the detergent to attack the deep down dirt that has worked its
way into the cleaning surface.
Trigger the gun 3 to 5 times to get any trapped air out of the
system.
