LIMIT SWITCH ADJUSTMENT
Refer to
Figures 2-15 and 2-16
with the following procedure.
NOTE:
To avoid operational “dead-spots”, adjust DEPLOY CUTOFF SWITCH before UP CUTOFF SWITCH.
NOTE:
When loosening adjustment screws, apply enough pressure to screw to move block instead of screw.
(The block might stick if insufficient pressure is applied to screw.)

a. Fully DEPLOY platform.
b. Adjust UP CUTOFF ADJUSTMENT SCREW and DEPLOY CUTOFF ADJUSTMENT SCREW 6-8 turns
counterclockwise
(CCW) 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
(CCW), push screw
forward, 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
(CCW), push screw forward, cycle plat-
form 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
(CW) until platform “jogs” down to vehicle floor level. Make sure that clearance between knuckle
actuator saddle and parallel arm is 3mm (1/8 in.) minimum (distance may be 13mm (1/2 in.) 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
(CW) until platform “jogs” up to vehicle floor level. Make sure that clearance between knuckle actuator
saddle and parallel arm is
3mm (1/8 in.)
minimum (distance may be
13mm (1/2 in.)
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.)
