How to Disassemble the
Mast Assembly
1 Remove the cable retaining fasteners from the
winch drum. Then remove all of the cable from
the drum.
2 Tip the machine backwards and rest the top of
the number one mast on an appropriate
support. The mast assembly should be level
with the carriage up.
Bodily injury hazard. Use proper
lifting techniques.
3 Remove the mounting fastener from the cable
anchor on the last column (carriage side).
4 Remove the cable from the mast by pulling on
the cable anchor end of the cable.
Bodily injury hazard. Cables can
fray. Always wear adequate hand
protection when handling cable.
5 Secure the hold-down latch
to its respective column
with a piece of tape, so that
it does not fall off during
disassembly.
6 Slide the carriage forward
about 1 foot (30 cm) to expose the column stop
mounting fastener attached to the bottom end
of the top column, below the carriage. Remove
the fastener and the stop.
7 Use a hex key wrench through the access
holes in the carriage to release the safety
brake. Slide the carriage away from the base
1 inch (2.5 cm) while reaching through both
slots. Position the hex key above the safety
brake rollers and pull back on the wrench.

8 Remove the carriage by sliding it out the
bottom of the mast towards the base while
holding the safety brake rollers in position with
the hex key wrench.
9 Repeat steps 6 through 8 for each remaining
column.
How to Release the Safety Brake
When Servicing the Mast
The safety brake system will lock when the
machine is tilted horizontally. When the brake is
locked, the columns can extend but not retract. If
the safety brake system locks while you are
servicing the mast, use one of the following
methods described below to release the brake.
A The first method allows you to release each
column successively starting at the carriage
and removing columns one by one. This is
described above in How to Disassemble the
Mast Assembly, steps 7 and 8.
B The second method allows you to release any
column in the assembly regardless of position
but requires a custom made tool. The tool is a
1
piece of /
in an L shape with one end 1 inch long and the
other end 16 inches long. The installation of a
handle on the 16" end will make it easier to
use.
Using the special tool, reach from the bottom of
the column and into the safety brake access
slot in the inner side wall of the column. Slide
the carriage away from the base about 1 inch
(2.5 cm) while reaching through the far upper
end of the slot. Position the short end of the
tool above the safety brake rollers and pull
back on the tool. Slide the released column
out the bottom of the mast assembly.
