2. Clear the cleaning area of all persons. Keep children and pets away.
3. Hold the spray gun firmly with two hands and a sturdy stance -- Gun
kicks back when triggered.
CAUTION : Spray gun metal gets extremely hot when using
the burner and can burn you on contact. Never touch the metal
screw or any metal parts of the spray gun when the heater is being
used. Use only designated grip areas.
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. (See Figure 11 below)
WARNING: 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.
