RAM START-UP PROCEDURE
1. Pre-fill all piping and ram(s) with oil.
2. Ensure that the factory shipping wire holding the ram plunger in position is removed
before operating the ram(s).
3.
Apply pressure to raise the ram about three feet. Loosen the bleeder screw in the
flange two to three turns. Air trapped in the bearing space will escape. Leave the
ram in this half-raised position until all of the bleeder air has escaped and clear,
bubble-free oil runs from the bleeder. Allow plenty of time for this procedure.
4.
Tighten the bleeder screw until snug. Don’t over tighten the screw as this can
cause damage to the rubber seal washer.
5.
Clean away all dirt, cement, sand, etc, from around the plunger and seal flange.
Pour a little oil around the seal and raise the lift a few inches to carry up any
remaining dirt particles.
6.
Wipe the plunger clean, lower it to the ground, and refill oil to the proper level.
7.
Raise the lift to its full height and apply full pressure to the system.
8.
Lower the lift slightly below full rise and crack open the bleeder screw again to
ensure that all air is out of the system. Re-tighten the bleeder screw.
9.
While full pressure is on the system, check all piping thoroughly for leaks.
10. If it is leak free, complete the backfilling and pour the concrete “top cap” in the pit
floor. Keep dirt and concrete away from the plunger and packing flange, as well as
the cable equalizer struts, when applicable. Wipe the plunger with an oil soaked
cloth to prevent rusting.
11. Let the concrete set for at least 24 hours, then recheck the plunger and seal-flange
for cleanliness.
SUMMARY – RAM INSTALLATION & START-UP
1. Set the rams in the pit. Be absolutely sure the rams are on pit centerline.

3. Connect the oil lines between the power unit and the rams.
