4. Hoist the Liftgate. Then,
place fl oor jack under
center of main frame (FIG.
22-1). Jack the Liftgate into
position. Make sure vehicle
fl oor is horizontal. Maintain
distance between fl oor and
top of main frame as shown
in FIG. 22-1.
Correct fl oor clearance must be maintained when Liftgate is in position and
being welded. Maintain distance between vehicle fl oor and top of main frame
at center of main frame as shown in the instructions. Dimension tolerance is
+/- 1/4”. Never apply force at the ends of the main frame tube to change the
fl oor clearance.
CAUTION
3. Make sure hoist is not
set up the incorrect way
(FIG. 22-1). Place a “C”-
clamp on each side of
platform (FIG. 22-1) to
prevent hoist chain from
slipping off platform.
Wrap chain around plat-
form (FIG. 22-1).
