1)
Remove the protective cap from the oil tank fill line and quick connect fitting
labeled "OIL" that is located at the bottom of the lower cylinder.
2)
Connect the ground oiling hose and quick connect fitting to the ground oiling
hand pump and place the ground oiling hand pump container cover on an oil
container filled with MIL-L-2104 15W40 oil.
3)
Install the ground oiling hand pump in the container cover.
4)
Connect the hose on the ground oiling hand pump to the oil tank fill line and
quick connect fitting (OIL) on the impact hammer.
5)
Manually pump oil to the lubricating oil tank on the impact hammer.
6)
Observe the oil tank plug/vent valve for evidence that the lubricating oil tank
is full.
7)
Disconnect the oil supply line and reinstall the protective cap.

If attached, disconnect the 89-inch lifting sling from the lower cylinder lifting lug and
connect the free end to the headache ball of the pile line (aux. hoist). If not
attached to the impact hammer, connect one end of the 89-inch lifting sling to the
upper cylinder lifting lug with a shackle and the free end to the headache ball of the
pile line (aux. hoist).
k.
Place wood blocking underneath the impact hammer and using the hammer line
(main hoist), lower the impact hammer along the lead tower to the wood blocking.
l.
Raise the pile line (aux. hoist) and apply nominal tension to it. Maintain holding the
impact hammer vertical with the hammer line (main hoist).
m.
Using the crane boom (combination of telescoping and booming up), raise the lead
tower above the lower and upper gibs on the impact hammer. Be sure to pay out
the hammer line (main hoist) and pile line (aux. hoist) cables while extending the
