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
customized for pressure washer use
on specific cleaning tasks. These
detergents are approximately as
thick as water. The use of thicker
detergents, such as dish soap, will
clog the chemical injection system
and prevent the application of the
detergent.
The cleaning power of detergents
comes from applying them to a
surface and giving the chemicals
time to break down the dirt and
grime. Detergents work best when
applied at low pressure.
The combination of chemical action
and high pressure rinsing is very
effective. On vertical surfaces,
apply the detergent starting at
the bottom and working your way
upward. This will prevent the
detergent from sliding down and
causing streaks.
