4. Wash from the bottom to the top, using side-to-
side motions. This washes away heavy dirt and
allows the detergent to soak as you work toward
the top.
5. Use the width of the spray pattern to wash a wide
path. Overlap spray paths for complete coverage.
6. The nozzle should be 12" to 24" from the work,
closer for tough areas.
7. Small parts should be washed in a basket so the
pressure does not push them away. Larger,
lightweight parts should be clamped down.
8. The pressure washer is set and locked to the
maximum rated pressure when it leaves the
factory. To reduce the pressure, turn the unloader
knob counterclockwise. To return to maximum
pressure turn unloader knob clockwise.
WARNING: Warranty Void
Do not attempt to alter the unloader valve's
maximum pressure. Excess pressure could
cause serious injury from escaping high-
pressure fluids and/or pump damage. Any
alteration other than turning the adjustment
knob will void your warranty.
