NOTICE:
Only use the CAR nozzle setting for washing the exterior
surfaces of cars and other motor vehicles. The use of any
other nozzle settings, including the soap settings, could
result in damage to vehicle paint and other vehicle parts.
Do not wash the engine or any electrical components
with your pressure washer, as these parts can become
damaged. We will not be responsible for any property
damage caused by using nozzle settings other than CAR
to wash motor vehicles exterior surfaces.
USING THE HIGH PRESSURE HOSE
WARNING:
Injection hazard. Fully unwrap and straighten high pres-
sure hose prior to and during each use and do not allow
it to become kinked. The high pressure hose features an
outer covering that provides strength to the hose. If the
outer covering becomes damaged, stop using the hose
and replace it immediately. A kinked or damaged hose
can develop a high pressure leak and result in a possible
injection or other serious personal injury.
To prevent damage to the outer covering:
 Inspect the hose before every use.
 Fully unwrap and straighten hose before use.
 Do not allow the high pressure hose to be kinked.
 Keep hose away from hot surfaces and sharp edges.
 Do not pull unit by high pressure hose.
 Do not allow hose to be crushed or wrapped around
objects.
WARNING:
Injection hazard. Fully unwrap and straighten high pres-
sure hose prior to and during each use. A kinked hose
can develop a leak and result in a possible injection injury.
WASHING WITH DETERGENT
See Figure 17 - 19.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact an authorized customer service center
for more information.
USE ONLY DETERGENTS DESIGNED FOR PRESSURE
WASHERS. Do not use household detergents, acids, alka-
lines, bleaches, solvents, flammable material, or industrial
grade solutions which can damage the pump. Many de-
tergents may require mixing prior to use. Prepare cleaning
solution as instructed on the solution bottle. Always test in
an inconspicuous area before beginning.
OPERATION
 Remove the cap from the detergent container and pour
detergent in the container. Replace cap on container.
NOTE: The machine setting of this unit is 20:1, which usu-
ally allows the use of 1 gallon pressure washer detergent
without further dilution. Check your detergent instructions
to be sure additional dilution is not necessary.
 Install 6-in-1 Change-Over Nozzle (if necessary). Rotate
the spray selector on the nozzle to either the short range
detergent ( ) or long range detergent ( ) setting.
 Squeeze the trigger and wait approximately 5 seconds
for the detergent to appear.
 Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
NOTE: To use a detergent bottle, open the detergent container
cap. Next, remove the filter from the end of the detergent
injection hose then slide the hose out of the cap. Place the
detergent injection hose filter back on the hose and place
the hose in the bottom of the bottle.
