unsafe operating condition.
Visually inspect the welds in the following
locations:
B-2
winch mounting plate
loading wheels/steer handle
base
legs and stabilizers
load handling attachment(s)
Clean the Columns
Clean columns are essential to good machine
performance and safe operation. Extremely dirty
conditions may require that the columns be
cleaned more often.
Raise all columns to the maximum height.
2 Visually inspect the inner and outer channels of
the columns for debris or foreign material. If
necessary, use a mild cleaning solvent to clean
the columns.
This procedure will require the use
of additional access equipment.
Do not place ladders or scaffold
on or against any part
of the
machine. Performing this
procedure without the proper skills
and tools may result in death or
serious injury. Dealer service is
strongly recommended.

Inspect the Mast Assembly
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.
Attach an overhead crane or similar lifting
device to the lifting bracket on the mast. Rotate
the carriage hold down bar over the carriage.
2 Lift the machine slightly and then guide it over
onto an appropriate support. The mast
assembly should be level with the carriage up.
Crushing hazard. The machine
will fall unless it is properly
supported with the overhead
crane.
3 Visually inspect the top
of each column for
clearance between the roller wheel and the
adjacent column surface.
0 Result: There should be a maximum gap of
0.062 inches (1.57 mm) between the roller
wheel and the column.
