4.7 Vibration Damper
A polyurethane damper is retained in the cage bottom adapter to absorb the recoil from the pile and
prevent damage to the hammer. The damper should be replaced if it becomes miss-shapen or burns
out due to overheating.
To access the damper remove the hammer by removing the M48 bolts securing the hammer to the
cage bottom adapter.
