• Pull back on the collar, insert the new nozzle and release
the collar. Tug 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 chemical injection siphon/filter into the
detergent container.
CAUTION! Keep the chemical injection tube
from coming in contact with the hot muffler.
• Make sure the black nozzle is installed.
NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Green, Yellow, or Red).
• Make sure the garden hose is connected to the water
inlet. Check that the high pressure hose is connected to
the spray gun and the pump and start the engine.
• Apply the detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes. Do Not allow the
detergent to dry on (prevents streaking).
• Allow the detergent to soak in between 3–5 minutes
before washing and rinsing. Reapply as needed to prevent
