Operation

Shut Down.

1.For normal system shut down, disconnect power to lubricator controller (J) by turning off the ignition switch, and turn off hydraulic supply by closing the ball valve (Fig. 2, item AA).

CAUTION

Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging pump. If your pump accelerates quickly, or is running too fast, stop the pump immediately and check the fluid supply.
