3.5.11 Clamp-Up Limit Switch Adjustment (Models: A and AEP)
The clamp-up limit switch determines where the clamp stops in the “up” position. If the clamp stops
too high or too low, adjust as follows:
1. Turn off the power and disconnect the power cord.
Attempting to adjust this limit switch or to move the clamp away
from the limit switch with out disconnecting power could cause the clamp motor to
inadvertently start up and cause severe injury. It is extremely important to disconnect power
while making this adjustment.
2. Remove and disconnect the display panel, then remove the top cover.
3. MAKE SURE POWER IS DISCONNECTED (see caution above) and manually move the
clamp down by first disengaging the motor brake (Figure 17), and then rotating the drive belt
or pulleys by hand.
