Big Eye Rip Fence System Troubleshooting: No Movement in Rear Clamping Mechanism When Lock Handle is Used

Created by Gabriel Izzo, Modified on Mon, 15 Apr 2024 at 03:45 PM by Gabriel Izzo

Before performing the following checks, please verify that if your table width requires the installation of the included Rod Sleeve onto the Lock Rod, it is installed correctly and the rear clamping mechanism adjusted for the table width before proceeding to the next steps. If you have a Harvey Alpha Series table saw, then the Rod Sleeve is not used as the main table width is already 800mm.

If moving the Fence Lock Handle up and down and there doesn't appear to be any movement in the rear clamping mechanism, please take the fence off of the rails and turn it over to expose the underside where you will see part 243 Locking Rod. 

When moving the fence lock handle up and down if you do not see any movement whatsoever in the Locking Rod shown in the photo, grab the rod with your hand and check for excessive play to determine if it could be separated internally at the front or rear.



If it has been determined that the rod is disconnected from the front clamping mechanism, the front outer shell will need to be removed to access the set screw part#218, loosen it, and check that the part#220 Pull Rod Lock Nut is secured to the Lock Rod before fully tightening the nut and set screw. 

1. Start by removing the six screws that secure the outer shell.



2. Loosen the set screw in on the end of the pull rod lock nut. 



3. If the pull rod lock nut is not connected to the rod, you can try to reseat the lock rod and thread the nut onto the end of the rod using a 10mm open end or socket.
 



3. Then once you have reconnected the separated lock nut and the lock rod, tighten the set screw and re-install the outer shell.
