Use three (3) 1/2-13 X 2" flat-head bolts, flat washers, lockwashers, and hex nuts (A) Fig. 1 to attach the guide rail to the front of the saw table (Fig. 2). Loosely tighten with the supplied hex wrench for further adjustment. A Fig. 1 Fig. 2 2. Use the template (A) Fig. 3 that is supplied with the fence system to check and adjust the level of the front rail (B) to both ends of the saw table. Tighten the guide rail hardware securely. NOTE: Do NOT level the rail with the extension wing. Use the saw table. 3. Place the guide tube (A) Fig. 4 on the saw table. Align the nine (9) threaded holes with the holes in the front ledge. A A B Fig. 4 Fig. 3 4. Position the guide tube on the front rail. Secure the guide tube with nine (9) 1/2" hex-head bolts and lockwashers (Fig. 5). 5. Place the rip fence on the guide rail. B A C Fig. 5 Fig. 6 6. Insert a bolt (A ) Fig. 6 up through the hole (B ) at the extreme right end of the guide tube. Thread the retaining nut (C) on the bolt (see the inset - Fig. 6) NOTE: This retaining nut prevents the fence from falling off the end of the guide rail. IMPORTANT: Before applying power to the saw, ensure that the rip fence is parallel to the miter gauge slot. Refer to the section "HOW TO OPERATE AND ADJUST THE RIP FENCE". HOW TO OPERATE AND ADJUST THE RIP FENCE 1. To move the fence along the guide rail, lift the clamp lever (Fig. 7). 2. To lock the fence in position, push down on the clamp lever (Fig. 8). NOTE: The clamp lever will remain in the "up" position when you move the fence. Fig. 7 Fig. 8 A The distance the fence is positioned from the blade is indicated by the witness line (A) Fig. 9 on the cursor. To adjust the cursor, test cut a workpiece with the fence locked in position. Measure the width of the workpiece. Loosen the two screws (B), adjust the cursor until the witness line (B) is aligned with the previous measurement. Tighten the screws. B Fig. 9 HOW TO ADJUST THE FENCE PARALLEL TO THE MITER GAUGE SLOTS IMPORTANT: Be certain that the miter gauge slots are parallel with the blade before adjusting the fence. Move the fence (A) Fig. 10 until the bottom edge is aligned with the edge of one of the miter gauge slots and lock it in place with the lock clamp (B). If the fence is not parallel to the slot, raise the lock clamp, and lift the fence off of the guide tube. Use a 3/16" hex wrench (not supplied) to tighten or loosen the adjustment screw (either C or D) Fig. 11 that applies. IMPORTANT: Any necessary adjustments should be very small. Fig. 10 C D A B Fig. 11 HOW TO ADJUST THE CLAMP HANDLE When the clamp handle is in the "down" position, the fence will lock to the guide tube. If this is not the case, lift the clamp handle and raise the fence assembly off of the guide tube. Slightly tighten the two adjusting screws (E) and (F) an equal amount, using a 3/16" hex wrench. Replace the fence assembly and check for correct clamping. Repeat as necessary. E F IMPORTANT: After adjustment of the clamp handle, check to see that the fence and miter gauge slots are parallel.
