Tools equired:
Phillips screwdriver
The control module is located on the lower back panel.
1. To access the control module, remove the four larger Phillips screws securing the lower por-
tion of the bellows to the clamshell covers. Each side has two screws located near the center
of the clamshell.
2. The bellows is still secured to the top of the clamshell covers, but now it can be lifted and
secured with bungee cords (see Figure 1.1). The table must be raised to its highest position
to allow clearance to access and remove the controller.
NOTE: If the table cannot be raised to the up position the covers must be removed. First remove the
remaining 12 Phillips screws securing the lower portion of the bellows to the covers. Next, separate
the covers by removing the four securing screws located at each end, and then slide the covers out.
3. Remove the six screws that secure the lower back panel (see Figure 1.2). Remove the lower
back panel. Slide the control module out carefully. Make sure that the connecting cables are
not being damaged as you slide the box out.
4. Disconnect all cables (see Figure 1.3).
5. Remove the six nuts that secure the module to the back panel.

1. Level and raise the tabletop to position 10 (the highest point).
2. Remove the eight 9/16-inch Tabletop bolts with a 9/16-inch wrench. Two of the bolts do
not have washers. This is to prevent the nylon wheel measuring device from getting hit by
the bolts. Place some sort of weight on the foot end of the table to support it from falling.
a. Move the tabletop all the way to position zero on the forward and back
(head end of the table) to access the four bolts.

8. You should now be able to remove the broken X-Mechlock and replace it with the new one.
9. After you have put the bolts back into place reconnect the Mechlock. Turn on the power
and test for correct operation. (You shouldn’t have to recalibrate the table for the X direction
because the pot that measures the location was not removed from the table.)
10. To remove the Y-Mechlock, remove the two Phillip screws that hold the bracket for the
nylon wheel and remove it from the table. Cut the zip tie that holds the power connector in
place with a wire cutter and disconnect the connector.
11. Remove the 3/16-inch Allen Head Pivot Bolt with a Allen Key by holding the 1/2-inch nut
with a 1/2-inch wrench. You should be able to slide the clevis block off of the pivot bolt.

15. To clean the piston on a Mechlock you must use either a contact cleaner or alcohol. Shoot
the solenoid a couple times after you apply the cleaner. This will help get any dirt inside
the solenoid. After you have the solenoid completely cleaned apply the C13349 Lubrication
to the piston and again shoot the piston.
16. Test for correct operation by sliding the tabletop side to side. If your pendant display does
not read L5 to R5 then you will have to do a side to side calibration.
17. If your table does not work properly please call 800-224-6339 ext. 2124 or 2125 for further
assistance.
NOTE: Always make sure that all of the plugs/connectors are completely in and that there are no bent or
pushed in pins. This may cause erratic operation.
