Maintenance

Flush the Pump With Compatible Solvent

WARNING

To reduce the risk of fluid injection injury, static sparking and splashing, read and follow Flushing Safety under FIRE OR EXPLOSION HAZARD on page 5.

1.Flush often enough to prevent fluid from drying in the pump and damaging it.

2.Always flush before storing.

a.If you are pumping water-based fluid, first flush the pump with water, then with mineral spirits or a compatible oil-based solvent.

b.Leave the mineral spirits or oil-based solvent in the pump to protect the pump parts from corrosion.

3.Be sure to eliminate all air from the system.

Tighten Threaded Connections

1.Before each use, check all hoses for wear or dam- age and replace as necessary. Be sure all threaded connections are tight, and leak-free.

2.At least every six months, check and tighten all threaded connections, including manifold screws, clamps, plugs, and valve screws.

Check and Service the Lubricator, Regula- tor, and Filter

Check and service according to the instructions sup- plied with them. See Manual 308169 for oil recommen- dations.
