Method 2
This procedure corrects another source of misalignment that occurs when the table’s orientation is not parallel with the guide rails.
1.Use the universal wrench to loosen (but not remove) the fasteners from either end of both guide rails. Move each rail away from the other, so that the horizontal rollers are clear of the right guide rail. See Figure 25.

3. If the table shifts to the right as it travels away from |
the user, a shim needs to be added to the guide roller |
furthest from the ruler guide. On the other hand, if |
the table shifts to the left, a shim needs to be added |
to the guide roller closest to the ruler guide. Remove |
the appropriate guide roller to insert a shim between |

2.Remove rubber cap A on the left side of the table. Loosen the exposed lock nut using a 13mm socket wrench. Use a flat screwdriver to turn the shaft of the roller clockwise to lower it by approximately 3/8 in. (9.5 mm). See Figure 26. Evenly lift up the table to disengage the guide rollers from the left guide rail. Once the guide rollers are clear, shift the table to the right to clear the left horizontal roller of the rail. Remove
the table from the guide rails. See Figure 27.

the roller and table, then reattach. See Figure 28. |
Depending on the severity of the shift, more than one |
shim may be required. |
4. After adding shim(s), mount the table onto the guide |
rails by reversing the instructions in step 2. Move the |
rails toward each other to engage the horizontal rollers |
to the right guide rail as shown in Figure 24. Realign |
the table to the blade using Method 1. Check to see if |
any shifting persists. A shift tolerance of 0.2mm (.008 |
in.) is allowed. A shift in excess of that will require |
further |
