To apply detergent follow these steps:
Detach the nozzle extension by pushing in and
turning it counterclockwise.
Remove the bottle from the foamer.
Align the locking tabs on the foamer with the groves
in the gun. Push inward and twist clockwise to lock
in place. (Note: make sure that the when you lock
the foamer into place you have the hose that con-
nects to the foamer bottle hanging downward.) See
Figure 12.
Prepare your detergent solution as required by your
job and fill bottle with the solution.
Attach bottle back onto foamer making sure the
bottle hangs down.
Start washer and apply detergent to a dry surface,
starting from the bottom and working up.
To rinse, you must, stop the pressure washer,
remove the foamer and connect the adjustable
nozzle extension.

Detergents are most effective applied to a dry
surface.
To Clean
Start at lower portion of area to be washed and work
upward, using long, even overlapping strokes. Deter-
gent or degreaser works best when you apply it to a
dry surface first. Let it set for 3-5 minutes before
washing and rinsing.
Rinse
WARNING: Be extremely careful if you
must use the pressure washer from a
ladder, scaffolding or any other relatively
unstable location. Pressure in a running
washer builds as you climb. When you
press the trigger, the recoil from the initial
spray could force you to fall. The high pres-
sure spray could also force you to fall if you
are too close to the cleaning surface.
Apply a high pressure spray to a small area and
then check the surface for damage. If no damage
is found, you can assume it is okay to continue
cleaning.
Start at the top of the area to be rinsed, working
down with same overlapping strokes as you used
for cleaning.
NOTE:
Never use garden hose inlet to siphon deter-
gent or wax.
Automatic Cool Down System
(also known as Thermal Relief)
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a tempera-
ture between 140145°F. When the water reaches
this temperature, the automatic cool down system
engages and cools the pump by
discharging the
warm water onto the ground.
This system prevents
internal damage to the pump.
