Nozzle Cleaning Instructions
(Continued)
• 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 5).

• 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.

Detergents
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 work 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.
