Inspect the Mast Assemblies
for Wear
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 Raise the platform until 3 to 5 inches (7.6 to
12.7 cm) of the top of each column is visible.
2 Visually inspect the top of each column for
clearance between the roller wheels and the
adjacent column surface.
Result: There should be a equal amount of
distance between the roller wheel and the
column on each side.
Note: If mast inspection results in a measurement
that is not within specification, refer to Repair
procedure 5-4,
How to Adjust the Glide Pads.
3 Loosen but do not remove the adjustment nut on
the sequencing cable.
4 Raise the platform approximately 3 feet (1 m).
