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

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.

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.
NOTICE:
USE ONLY DETERGENTS DESIGNED FOR PRES-
SURE WASHERS. Do not use household detergents,
acids, alkalines, bleaches, solvents, flammable material,
or industrial grade solutions, which can damage the
pump or cause property damage. Many detergents may
require mixing prior to use. Prepare cleaning solution
as instructed on the solution bottle. Always test in an
inconspicuous area before beginning.
To clean:
 Disconnect pressure washer from power supply.

to prevent accidental spilling of the detergent outside the
tank. If any detergent is spilled during the filling process,
make sure the unit is cleaned and dried before proceed-
ing.

overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
To rinse:
 Using the 15º nozzle, spray away from the rinsing surface
for approximately 10 seconds to allow any remaining
detergent to be flushed from the line.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
Before shutting off the motor:
 Fill the soap tank with clean water.
 Spray the clear water through the spray wand until the
tank is empty.
