CEILING CLOSURE PANEL ADJUSTMENTS
Referring to Figures 2a and 2b, the ceiling closure panel maybe adjusted to flush with the ceiling bottom.
The following steps describe the procedure.
Warning: It is important that regardless of how the ceiling closure panel has been set, the traveling
platform must trips the up direction shut-off switch when the lift retracted to the fully up
position. Failure to perform this check will reduce the motor’s life expectancy and void
warranty.
Note: When the ceiling closure panel closed either 1/2 inch lower or higher than the ceiling bottom,
adjustments must be done by the four suspended threaded rods.
