Step 5
With the ramp in the upright position, fasten
the rubber belt on the step bolt of the ramp.
Note: To properly align the locking pin and
the fixed plate, the upper ramp (19) and the
rubber foot of the lower ramp (20) must be in
contact with each other. Both sections of the
ramp need to be moved together to allow the
proper angle for the locking pin to align with
the hole on the fixed plate.
