a. Fully DEPLOY platform.
b. Adjust UP CUTOFF ADJUSTMENT SCREW and DEPLOY CUTOFF ADJUSTMENT SCREW 6-8 turns
counterclockwise
and then push screws FORWARD.
c. Cycle platform to STOW then DEPLOY.
d. When in DEPLOY position, platform should stop at an angle and NOT even with vehicle floor. If not, turn
DEPLOY CUTOFF ADJUSTMENT SCREW an additional 2-3 turns
counterclockwise
, push screw for-
ward, STOW then DEPLOY platform, then repeat this step.
e. Cycle platform to UP position.
f. When in UP position, platform should stop short of vehicle floor level. If not, turn UP CUTOFF
ADJUSTMENT SCREW an additional 2-3 turns
counterclockwise
, push screw forward, cycle platform
DOWN then UP, then repeat this step.
g. Cycle platform to STOW then DEPLOY.
h. Push and hold control pendant DEPLOY switch. Slowly turn DEPLOY CUTOFF ADJUSTMENT SCREW
clockwise
until platform “jogs” down to vehicle floor level. Make sure that clearance between knuckle ac-
tuator saddle and parallel arm is 1/8" minimum (distance may be 1/2" maximum and unequal from left or
right arm), stop turning screw and release DEPLOY switch.
i. Position platform DOWN to ground level then UP until it stops.
j. Push and hold control pendant UP switch. Slowly turn UP CUTOFF ADJUSTMENT SCREW
clockwise
until platform “jogs” up to vehicle floor level. Make sure that clearance between knuckle actuator saddle
and parallel arm is 1/8" minimum (distance may be 1/2" maximum and unequal from left or right arm), stop
turning screw and release UP switch.
NOTE:
If lift does not operate after 1-2 full turns of adjustment screw, cycle platform UP and DOWN (The UP
CUTOFF SWITCH is less sensitive than DEPLOY CUTOFF SWITCH.)

ADJUSTMENT PROCEDURE
Fold cutoff
actuator
Lift does not fold
tightly.
Rotate actuator coun-
ter-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 con-
tinuously.
Rotate actuator
clockwise.
Test lift. Pump should cutoff when lift is
folded tight.
