With the power off, set the collar between the proximity switches and then turn on power.
Press cut buttons once to turn on the hydraulic motor. The knife will move to the absolute top
of its stroke. Move the collar to the top proximity switch until LED turns on, then move it an
additional 1/4” higher and tighten its setscrew. An indicator light on the switch body comes on
when the switch is actuated (proximity switches must be within 1/8” (3.2mm) to actuate).
Send the knife down using the “Knife Change” feature found in the Maintenance pull-down
menu. Check the distance between the proximity switch and the actuator.
2. Hydraulic Up Proximity Switch
The Hydraulic Up Proximity Switch is mounted on the lower left rear of the machine frame
(Figure 36).
Figure 36
An indicator light on the switch body comes on when the switch is actuated (proximity
switches must be within 1/8” (3.2mm) to actuate). The switch senses the extension of the
clamp cylinder at the top of its stroke. This stops hydraulic power to the clamp and knife. If
the switch is not properly set, the knife and clamp cylinders will be under constant load
(indicated by excessive heat and noise).
To adjust:
a. Loosen the bottom lock nut and turn the top lock nut down to raise the switch.
b. Turn on the machine and press the cut buttons once to start the hydraulic motor.
c. The knife and clamp will move to the extreme up position and a load will remain on the
hydraulics.
d. When the cylinder has stopped moving, pass a metal object in front of the switch to
actuate it and take the load off the hydraulics. Keeping pressure on the switch to hold it
against its mounting bracket, turn the lock nut up to lower the switch until the indicator
light in the switch comes on. Tighten the lower jam nut.
e. Press the cut buttons to cycle the clamp and check clamp position.
3. Clamp Up Proximity Switch
The Clamp Up Proximity Switch is mounted inside the upper rear cover on the back of the
frame (Figure 37).
