ACTION
ADJUSTMENT PROCEDURE
Fold cutoff
actuator
Lift does not
fold tightly.
Rotate actuator
counter-
clockwise.
With lift fully folded (handrails should be
folded tight against vertical arms), rotate
actuator so that it barely trips fold cutoff
switch.
Pump runs
continuously.
Rotate actuator
clockwise.
Test lift. Pump should cutoff when lift is
folded tight.
Up cutoff
adjustment
screw
Lift stops
low.
Adjust screw
clockwise.
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.)
Lift stops
high.
Adjust screw
counter-
clockwise.
Deploy cutoff
adjustment
screw
Lift stops
low.
Adjust screw
counter-
clockwise.
Adjust deploy limit switch so that lift stops
just below "Up" cutoff described in above
step. This will give the necessary overlap
to avoid "dead" spots.
Lift stops
high.
Adjust screw
clockwise.

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 ground level.
b. Refer to
Figure 2-11
. Adjust left and right platform set screws until platform is level at zero 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 plat-
form.
c. Repeat steps a and b as required to achieve proper rollstop operation.
