C-1
Inspect the Mast Assembly for
Wear
Genie specifications require that this procedure be
performed every 1000 hours or annually,
whichever comes first.
Detection of excessive or unusual wear in the mast
assembly is essential for safe machine operation.
An unsafe working condition exists if the mast
assembly has excessive wear and/or does not
operate smoothly, free of hesitation and binding.
1 Attach a lifting strap from an overhead crane
or similar lifting device to the lifting point on the
top of the mast. Rotate the carriage hold-down
bar over the carriage and operate the winch to
apply tension to the lifting cable.
2 Lift the machine slightly with the overhead
crane and guide it onto a suitable structure
capable of supporting it.
Crushing hazard. The machine
will fall if not properly supported
by the overhead crane.
3 Lower the top of the mast onto the suitable
structure.
4 Attach a lifting strap from an overhead crane
to the base of the machine.
5 Lift the base with the overhead crane, until the
mast is level and place another suitable
structure under the mast.
6 Lower the base end of the machine.
7 Rotate the mast assembly until the carriage is
on top.
8 Visually inspect the top of each column for
clearance between the roller wheel and the
adjacent column surface.
Result: There should be a gap of less than
0.062 inch / 1.57 mm between the roller wheel
and the column.
Note: If the mast inspection results in a
measurement that is not within specification, See
Repair Procedure,
How to Disassemble the Mast
Assembly.
9 Visually inspect the bottom of each column for
clearance between the roller wheel and the
adjacent column surface.
Result: There should be a gap of less than
0.062 inch / 1.57 mm between the roller wheel
and the column.
Note: If the mast inspection results in a
measurement that is not within specification, refer
to Repair Procedure,
How to Disassemble the Mast
Assembly.
10 Grasp the bottom of the carriage and lift it
approximately 12 inches / 30.5 cm, then
release the carriage.
Result: The carriage should stop within 5 to
8 inches / 12.7 to 20.3 cm and the safety
brake should engage.
Crushing hazard. Do not stand
directly under the carriage or
load handling attachment.
