instructed to relieve the pressure, follow the Pressure
Relief Procedure.

Pressure Relief Procedure

slider valve (F).
2. Set the ram director valve to DOWN. The ram will
slowly drop.
3. Jog the director valve up and down to bleed air from
ram cylinders.

Disassembly

shrouds. Loosen six captive screws (A) and disas-
semble shrouds (B) from supply system.

If you are not replacing the manifold (1), you may
prefer to remove the bracket from the ram and
leave it attached to the integrated air controls
because the screws are easier to reach. See F
