Adjust up cutoff switch so that lift stops just
before first knuckle actuator saddle or roller
touches underside of lower parallel arm.
(Saddle or roller should be about 1/8" from
lower parallel arm.)

1. PLATFORM
TILT
ADJUSTMENT
Correct platform tilt adjustment is crucial for proper platform rollstop operation, but cannot be adjusted at factory.
Factors such as vehicle floor height, lift tilt angle and stiffness of vehicle springs will vary installation geometry.
a. Deploy and lower lift platform to a position halfway between vehicle floor level and ground level.
b. Refer
to
Figure 2-15
. Adjust left and right platform set screws until platform is level at zero (0) degrees.
Turn setscrews clockwise to angle front-end of platform upward, or counter-clockwise to angle downward.
NOTE:
At ground level, the distance between heel of platform and ground should be 3/4" to 1". This distance
should be measured at initial point of rollstop full deployment.
NOTE:
Adjust setscrews on both sides of platform simultaneously and evenly to ensure proper leveling of platform.

c. Repeat steps a and b as required to achieve proper rollstop operation.
CAUTION
Do not lengthen tie rod stud to point where panel will lift off its tab support (at center of lift fork).
d. Adjust left tie rod assembly. Adjust tie rod stud until nearly all of link free-play is out by lengthening rod.
