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.
