1. Turn release valve counterclockwise to allow ram
to fully retract. It may be necessary to apply force
to the saddle for lowering.
2. Remove the inspection plate.

2. Pump handle eight full strokes.
3. Turn release valve clockwise to close valve.
4. Pump handles until the ram reaches maximum
height and continue to pump several times to
remove trapped air in the ram.
5. Carefully and slowly pinch oil fill plug to release
trapped air.
6. Turn release valve counterclockwise one full turn
and lower ram to the lowest position. Use force
