The measurement should be the same at both ends of the rear rail. Adjust as needed.

3.Tighten the three screws with a 12mm wrench.

Front Rail and Guide Tube

Refer to Figure 6.

4.Install the front rail to the front edge of the table, using two 5/16-18 x 3/4 hex cap screws (AA), two 5/16 lock washers (BB), and two 5/16 flat washers (CC), through the slotted holes in the rail. Place the screws approximately center of the slots; this can be adjusted later as needed. Tighten the two screws with a 12mm wrench.

5.Install the guide tube to the bottom holes in the front rail, using five 5/16-18 x 3/4 hex cap screws (AA), five 5/16 lock washers (BB), and five 5/16 flat washers (CC). Hand tighten only. Pull the guide tube away from the table as far as it will go, then tighten all five screws in the guide tube with a 12mm wrench. Do not overtighten.

Fence Assembly

Refer to Figures 7 and 8.

Place the fence body onto the guide tube (as shown in Figure 8). Raise the fence lever all the way up to install or remove the fence from the guide tube. Midway lever position allows the fence to slide along the guide tube. Lowest lever position locks the fence in place.

Resaw Fence

Refer to Figures 8 and 9.

Loosen the lock bar using the knobs, until the lock bar protrudes enough to slide the aluminum resaw fence on from one end, as shown in Figure 8. Re-tighten the knobs.

NOTE: The aluminum resaw fence can be installed in one of two positions; vertically (resaw position), as shown in Figure 8; or horizontally as shown in Figure 9. Horizontal position is useful for smaller workpieces. (The zero setting of the cursor cannot be used with the horizontal fence position.)
