Hammer
following procedure:
NOTE
There are a total of twelve lubrication fittings
on the impact hammer that require grease
and two lubrication fittings that require oiling.
Refer to Figure H-16 for Locations.
The pile gate must be removed before
performing the following procedure.
a.
Ensure the Load Moment Indicator (LMI)
system on the crane is configured for Front
Hoist, Outrigger Position 100%, and Two (2)
Parts of Line.
b.
Set the square (concrete) pile adapter
upright and place on wood blocking so that it
is aligned directly underneath the direct
drive assembly of the impact hammer.
c.
Using the hammer line (main hoist), slowly
lower the impact hammer onto the square
pile adapter with the adapter sliding fully into
the direct drive assembly. This will move
the piston up into the lower cylinder and
ensure that grease is distributed evenly.
d.
Have the crane operator turn the CRANE
FUNCTION POWER switch to the OFF
position to remove power from the crane
functions controlled by the armrest joysticks.
This prevents accidental operation of the
controlled crane functions caused by
bumping the joysticks.
e.
Ensure the two fuel tank plug/vent valves,
located on the top of the fuel tank, are fully
open.
f.
Ensure the oil tank plug/vent valve, located
on the top of the lubricating oil tank, is fully
open.
