5. STOW LOCK SETTING
The proper stow lock setting is determined by the position of the carriage assembly safety
blocks relative to the position of the carriage stop blocks attached to the enclosure assembly
at the rear of the lift. Refer to Figure [2-10]. Setting the stow lock mechanism requires the
adjustment of two (2) carriage stop block set screws so that the stow lock hook is properly
engaged by the stow lock striker plate.
FIGURE [2-10]: STOW LOCK HOOK ADJUSTMENT
a. Stow the lift completely inside the lift enclosure. The spring-loaded stow lock handle
located on the left-side of the enclosure assembly must be in its "down" position, with the
stow lock hook engaged by the stow lock striker plate.
b. Determine how much adjustment is required. The distance between the deploy lock hook
and striker plate should be no more than 1/16". If the distance is out of tolerance or the
stow lock mechanism does not engage properly, proceed with this adjustment procedure.
c. Make sure lift is fully stowed.
d. From the rear of the lift, remove plugs from rear channel left/right carriage stop blocks
access holes.
e. With an allen wrench, turn the stop block set screws clockwise to decrease the gap
distance, or counter-clockwise to increase the gap distance. One (1) full turn is equivalent
to 1/16" of adjustment. Be sure to adjust set screws simultaneously an equal number of
turns.
f. Repeat check procedure as described above and adjust set screws as required until the
proper gap distance is achieved. Deploy and stow the lift several times to ensure proper
operation of the stow lock mechanism.
