The Up Limit Switch cuts power to the Lift Sole-
noid when the platform is fully elevated, prevent-
ing the Lift Cylinder from bottoming out. The Up
Limit Switch is a mercury switch that is located
just in front of the right rear scissor pivot on the
lower inner scissor assembly.
To adjust the switch, disconnect the wires to the
switch and install a jumper, connecting the wires
together. Slowly elevate the platform to full
height. Place a mark on the chassis where the
scissor slide block currently is. Lower the plat-
form just enough to move the slide block
(7-13 mm). Mark this location. Install a continuity
tester or ohmmeter across the Up Limit Switch.
Rotate the switch until it just opens. Secure the switch with the mounting screw and reconnect the
wires to the switch
Lower and raise the platform to verify the adjustment. The slide block should stop at the second
mark on the Chassis.
