tering fluid if the can leaks at the seam.

ative to the wiper plate. See Start and Adjust the
Ram on page 10.
9. Clamp the can in place.

Shutdown and Care of the Pump

Never leave water or water-based fluid in a carbon
steel pump overnight. If you are pumping
water-based fluid, flush with water first, then with a
rust inhibitor, such as mineral spirits. Relieve pres-
sure, but leave rust inhibitor in the pump to protect
parts from corrosion.
1. Stop the pump at the bottom of the stroke to prevent
fluid from drying on the exposed displacement rod
and damaging the throat packings.
