Setup

5.Be sure your system is properly grounded before operating it. Read and follow the warning section, FIRE OR EXPLOSION HAZARD, on page 4. Use the grounding wire and clamp (47) when- ever the sprayer is used as a stationary unit.

6.Fill the gas tank. See Fueling, page 8.

7.Flush the pump to remove the lightweight oil which was left in the pump to protect it from rust.

a.Before using water–base paint, flush with mineral spirits, followed by soapy water, and then flush with clean water.

b.Before using oil–base paint, flush with mineral spirits, only.

c.See Flushing on page 11 for the flushing procedure.

8.Prepare the paint according to the manufacturer’s recommendations.

a.Remove any skin that may have formed.

b.Stir the paint to mix the pigments.

c.Strain the paint through a fine nylon mesh bag (available at most paint dealers) to remove the particles that could clog the filter or spray tip.

This is probably the most important step toward trouble–free spraying.

9.Keep the sprayer upright and level during operation and whenever it is being moved. See the last CAUTION on page 9.
