30 INSTALLATION INSTALLATION MANUAL
15) Fasten a short U-frame to each end of the front
frame cut-out and then install the entire
assembly between the front posts. Use four
hexagonal 5/16
″-18 x 2″ bolts, four 5/16″-18
nylon-insert lock nuts and eight
5/16″ washers
per side. Use 1/2″ (13 mm) socket wrench and
spanner. (Figure 59)
16) Verify whether the drive shafts fell off during
installation. If so, review the previous steps. If
not, tighten all U-frame bolts.
DANGER

Failure to verify the drive shafts installed could
result in the non-motor-side jacks elevating on
their own.
17) Once all the drive shafts have been installed,
the jack lock brackets located at the bottom of
the non-motor-side jacks can safely be
removed. Remove the Phillips M4 x 8 mm
screws. With the jack lock removed, screw back
in only the M4 x 8 mm screw. Keep the lock
bracket and the hardware for future use. (Figure
60). You can now remove the red paper tags
that are attached to the jacks.
WARNING

Failure to remove this part will break the lifting
mechanism.
