How to Adjust the Lifting Chains
When adjusting the lifting chains, it is very
important to maintain equal adjustment for both
mast assemblies.
1 Fully lower the machine and check to see if all
the columns (except the carriage) are even at
the top. The chains are adjusted correctly if all
the columns are even at the top.
To adjust column chains:
2 Mark the column to be adjusted.
3 Raise the platform 6 feet (2 m).
4 Turn the adjustment lock nuts evenly on both
chain terminals clockwise to raise the column or
counterclockwise to lower the column.
5 Fully lower the machine and recheck the
alignment of the columns. Re-adjust if
necessary.
6 Check to make sure the chain terminals on
each column have equal tension and the lock
nuts are tight.

How to Adjust the Glide Pads
When adjusting the glide pads, it is very important
to maintain equal adjustment for both mast
assemblies.
1 Fully lower the platform, turn off the machine
and remove the key.
2 Locate the upper and lower glide pad bolts
below each top roller wheel bolt on both sides
of the columns.
3 Hold each glide pad bolt and loosen the lock nut
on all the glide pads.
4 Turn all the glide pad bolts clockwise until the
glide pads make contact with the column.
Adjust both sides of the mast. Be sure the sides
of the columns are within
1
/
8
inch
(3.175 mm) to even with each other.
5 Starting at the number 1 column, torque the
upper and lower glide pad bolts to 12 in-lbs
(1.356 Nm). Hold the glide pad bolt and tighten
the lock nut. Be sure the glide pad bolt does not
turn.
6 Repeat step 5 for each remaining upper and
lower glide pad bolt on one side of the mast.
Start at the number 1 column and adjust each
column, working toward the carriage.
7 Repeat step 5 for all of the upper and lower
glide pad bolts on the other side of the mast.
Note: Make sure glide pad bolts are adjusted
evenly on each side to maintain squareness of the
columns.
