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.
High pressure rinsing should also
progress from the bottom to top.
On particularly tough stains, it
may be necessary to use a brush in
combination with detergents and
high pressure rinsing.
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. Keep
hands clear of the front of the
lance to prevent injury.
