5.7 MAST ASSEMBLY AND DISASSEMBLY
PROCEDURES
The MVL/MSP lift mast sections are constructed of extruded
aluminum, protected with an anodized surface finish. The
mast sections are interlocked into each other when assem
-
bled, by internally mounted slide pads at the top and bottom
of each mast section. These slide pads run up and down in
slide pad channels on each side of the mast.
The MVL/MSP model mast assembly contains a different num
-
ber of mast sections as shown following;
Assembly procedures for all mast sections is basically the
same, carefully slide the mast sections together until mast
ends are even.
(When sliding the mast sections together, be care
-
ful not to scratch the anodized surface).
Assemble the hardware
to the bottom of mast section first, slide this section out the
top of previous section and assemble hardware to the top of
mast. Always install slide pad shims with slide pads inserted
into the slide pad channels,
(ends of mast sections even).
Apply
-
ing silicone spray onto the slide pads and slide pad channels
before assembly will help mast sections slide easier after slide
pads have been properly shimmed.
Mast Disassembly Procedure - MVL/MSP
1.
After the mast assembly has been removed from the
machine, lay the mast assembly down on a suitable
work table with the platform mounting section on top,
facing up.
2.
Remove the sequencing cables and hardware from the
sides of the mast assembly. Also remove the covers from
the top of the mast assembly.

At the TOP of mast section-5, pull chains out and allow
to hang loose.
(Be certain floor surface is clean and free of
any metal chips or debris which may stick to lubricated
