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.
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 the unit.
•
Turn off the water supply.
Relieve any pressure trapped
in the hose by squeezing the
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.
•
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.
The use of detergents can
dramatically reduce cleaning time
and assist in the removal of difficult
stains. Some detergents have been
