nstallation
All chains should also be adjusted for equal tension of the
pairs to ensure proper load distribution and mast opera-
tion. Chains are adjusted at the chain anchors (see
Figure 6 ). To determine equal tension, extend the
unloaded mast to put the chains under tension. Then press
the center of the strand with your thumb. Then press
at the same place on the other chain of the pair. Each
chain in a pair should have equal “give”.
If the uprights or carriage are not in correct adjust-
ment, of if the chain pairs do not have equal tension,
perform the
Main Lift and Free Lift Chain Adjustments
as described in Section 5.6-3 and 5.6-4.

Inspect the upright channels for lubrication. If necessary,
lubricate the full length of each upright channel with
chassis lube or Kendall SR-12X (see Figure 7).

Mast Skewing
Extend the mast to full lift height and inspect for mast
skewing (see Figure 8).
* If the mast bends to the right at full extension, a shim(s)
needs to be removed from the left main lift cylinder rod.
* If the mast bends to the left at full extension, a shim(s)
needs to be installed on the left main lift cylinder rod.
To adjust the Mast to eliminate skewing, perform the
Mast
Skewing Adjustment
as described in Section 5.5-6.
