The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are

using may be contaminated by the oil, flush it out with a compatible solvent before using the pump.

Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system. Check with your fluid manufacturer or supplier for rec- ommended flushing fluids and flushing frequency. Always flush the pump before fluid dries on the displace- ment rod.

CAUTION

Never leave water or water-based fluid in a carbon steel pump overnight. If you are pumping a water-based fluid, flush with water first. Then flush with a rust inhibitor, such as mineral spirits. Relieve pressure, but leave rust inhibitor in pump to protect parts from corrosion.

1.Follow Pressure Relief Procedure on page 12.

2.Remove the spray tip/nozzle from the gun/valve.

3.Hold a metal part of the gun/valve firmly to the side of a grounded metal pail.

4.Start the pump. Always use the lowest possible fluid pressure when flushing.

5.Trigger the gun/valve.

6.Flush the system until clear solvent flows from the gun/valve.

7.Relieve the pressure.

Keep hands and fingers away from the priming piston during operation and whenever the pump is charged with air. The priming piston extends beyond the intake housing to pull material into the pump and can ampu- tate a hand or finger caught between it and the intake housing. Follow the Pressure Relief Procedure on page 12 before checking, clearing, or cleaning the priming piston.

1.Supply fluid to the pump, per the requirements of your system.

2.Be sure the pump air regulator is closed.

3.For D200s, D200, D60, and S20 Air Controls:

a.Set ram air regulator to about 50 psi (3.5 bar).

b.Set the ram director valve to down.
