4.4 Hand Pump
4.4.1 2-Way Remote Electric without ESD solenoid function
NOTE:
Hand Pump Isolation Valve (8)
The components referenced below are referencing Schematic 4.4.1. and is for
illustration purposes only. When using this procedure refer to the Bettis EHO Actuator
General Arrangement Drawing and Hydraulic Schematic for the unit being worked on.
4.4.1.1 Check the Reservoir (I) to see the hydraulic is at the proper level.
4.4.1.2 Rotate downward in the horizontal position both Hand Pump Selector
Valves (M).
4.4.1.3 Select and push inward the open or close knob located on the Hand
Pump Selector Manifold (L).
4.4.1.4 Use supplied Hand Pump Handle to discharge hydraulic fluid into the
open or close side of the actuator cylinder.
4.4.1.5 Continue hand pumping until the actuator completes the open or
close stroke and contacts the actuators adjustable end stops.
4.4.1.6 Once completion of the Hand Pumping operation, push the Pump By-
Pass Valve located on the top of the Hand Pump Selector Manifold (L)
and pull the pump handle downward retracting the pump ram into the
pump body.
4.4.1.7 Rotate both Hand Pump Selector Valves back into the upward vertical
position.
4.4.1.8 Check the Reservoir (I) to see the hydraulic fluid is at the proper level.
