How to Use the Nozzles
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408 .
DANGER
! Never exchange nozzles without
locking the safety latch on the trigger.
The quick–connect on the nozzle extension allows you
to switch between five different nozzles. The nozzles
vary the spray pattern, as shown below in Figure 11.
Follow these instructions to change nozzles:
• Engage the safety latch on the spray gun.
• Pull back the collar on the quick–connect and pull
the current nozzle off. Store the nozzle in the space
provided on the handle.
NOTE: For a more gentle rinse, select the white 40° or
green 25° nozzle. To scour the surface, select the
yellow 15° or red 0° nozzle. To apply chemical, select
the black nozzle.
• Pull back on the collar, insert the new nozzle and
release the collar. Pull on the nozzle to make sure it
is securely in place.
• For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from the cleaning
surface. If you get the spray nozzle too close, you
may damage the cleaning surface.
Cleaning and Applying Chemical
WARNING!
You must attach all hoses before
you start the engine. Starting the engine without
all the hoses connected and without the water
turned ON will damage the pump.
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
• Review the use of the nozzles.
• Prepare the detergent solution as required by the
manufacturer.
• Place the small filter of the chemical injection tube
tube into the detergent container.
CAUTION!
Keep the chemical injection tube
from coming in contact with the hot muffler. This
will damage the chemical injection tube. When
inserting the filter into a chemical bottle, route
the tube so as to keep it from inadvertently
contacting the hot muffler.
• Make sure the black nozzle is installed on the nozzle
extension.
NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Green, Yellow, or Red).
