Lift Cylinder Installation
1. Remove the lift cylinder packaging and inspect it for damage.
2. See Figure 8-7. Install the trunnion flange on the new cylinder.
3. Thread the locknut on the new cylinder rod, then thread the clevis all the
way onto the new cylinder rod and lock it in place with the locknut.
4. Unsnap the clevis pin clip from the clevis and remove the pin.
5. Remove the four M8 x 75 screws from the bottom of each side of the
bearing block and lift off the bearing caps.
6. Remove the bearings from the bearing caps. Install the bearings on the
cylinder trunnions, with the bearing flanges toward the cylinder.
7. Install the cylinder through the square opening in the roof of the feed
center, then carefully guide the bearings into the trunnion support block.
8. Install the bearing caps on top of the bearings, noting that the bearing
caps have position letters stamped on each cap which match letters
stamped on the block. Reinstall with the matching letters aligned.
Secure the caps to the support block with the four M8 x 75 screws.
9. Connect air tubing to the cylinder:
S 6-mm tubing from Down regulator to upper flow control valve.
S 6-mm tubing from Up regulator to lower flow control valve.
S 6-mm tubing from solenoid #3 SOL326 to the cylinder lock.
10. Rotate the E-Stop button on the feed center control panel clockwise to
release it and turn on feed center power and air.
11. Lower the cylinder clevis down the the lance carriage, which should be
resting on the stop bolt at the bottom of the V-track rail.
12. Connect the clevis to the lance carriage with the clevis pin. Snap the pin
clip around the clevis.
13. Install the proximity switches on the cylinder at the same positions as on
the old cylinder:
S LS306: Hopper position
S LS307: Box position
S LS308: Purge position
14. Adjust the position of the purge proximity sensor (LS308).
a. Slide the switch up or down until it senses the magnet in the cylinder
piston and the LED lights.
b. Note the position where the LED turned on, then continue sliding it in
the same direction until the LED turns off.
c. Slide the switch back up and position it in the midpoint between the
off positions and secure it in place.
NOTE: Refer to Lift Cylinder Proximity Switch Adjustment in the Installation
section of this manual (page 3-11) to set the positions of the Box switch
(LS307) and the Hopper switch (LS306).
15. Raise and lower the lance assembly and adjust the cylinder flow control
valves for 6 seconds full travel in each direction.
