supply, and shut off the water supply. Pull trigger to
release water pressure.
 Engage the lock-out on the trigger handle by pushing up
on the lock-out until it clicks into the slot.

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.
WASHING WITH DETERGENT
See Figures 19 - 20.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact customer service or an authorized 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.
OPERATION
 Disconnect pressure washer from power supply.
 Pour detergent in the soap tank. Use a funnel, if needed,
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
proceeding.
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 the blue or black soap nozzle on the spray wand.
 Connect unit to power supply and turn the pressure
washer on.
 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.
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.
 If any detergent remains in the spray, repeat with a second
tank of clean water.
 Shut off the motor.
NOTE: Shutting off the motor will not relieve pressure in the
system. Pull trigger to release water pressure.
RINSING WITH THE PRESSURE WASHER
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Remove the soap nozzle and place it in the nozzle storage
area on the machine.
 Select the right nozzle for the job. See the chart shown
earlier in the manual to select the appropriate nozzle.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
USING PUMP PROTECTOR
See Figure 21.
Regular use of a commercially available pump protector
prolongs the life of the pressure washer by removing hard
water mineral deposits, lubricating pump seals and pistons,
and preventing freeze damage. Pump protector should be
added to the unit after every use and before storage. Pump
protector can be purchased at the retailer where you pur-
chased your pressure washer, or by calling customer service.
The instructions that follow are typical for adding pump pro-
tector but you should always verify the specific instructions
provided by the manufacturer of the pump protector used.
