DANGER !
To avoid personal injury, NEVER go under the lift platform until the load is
removed and the scissors mechanism is securely blocked in the open position.
See "Lift Blocking Instructions" section.
PROBLEM POSSIBLE CAUSE AND SOLUTION
Platform jams during downward
stroke. Stop the lift immediately
if it has not already stopped
automatically. • If the top plate of the column is still in its pocket
under the top platform and the vertical band is
still in the groove of the horizontal band, the lift
may be jogged up until the column bears the
weight of the table. Remove the load from the
platform and remove the source of the
obstruction. Carefully inspect the extended
column of the lift to ensure that the vertical band
is properly seated in the groove of the horizontal
band throughout. Lower and raise the table
once with no load.
• The top plate of the column has come out of the
pocket of the top platform and the column has
rotated so that the top plate is no longer aligned
with the pocket, but the vertical band is properly
seated in the groove of the horizontal band.
Block the platform in its position and verify that
the platform won’t move. Remove the load.
Rotate the column from the top plate, by hand,
maintaining a downward pressure until the top
plate is aligned with the pocket on the underside
of the platform. It is advisable to use some
weight (50 pounds) over the top of the column to
perform this operation until it is brought close to
the top platform. Jog the lift drive upward until
the top plate enters the pocket and bears the
weight of the load. Proceed with the corrective
measures described above.
