D. CONNECTING CRANE LINE TO HAMMER
Connect the crane line directly to the hammer using the lifting sheave. The

To lift the hammer to a vertical position, first remove the rope guide bolt and sleeve.
(See Fig 2) Pass the crane wire rope around the lifting sheave and re-attach to
crane boom. Lift hammer to the vertical position. Re-install rope guide bolt and
