FOR DEL TA SAWS ONLY
(Except Models 34-670, 36-380 and 36-600)
2. Align the two holes (E) Fig. 6, in the front rail (C) with the two through holes in the saw table and fasten the rail (C) to the
table saw using the two 3/8-16 x 1-1/4” long flat head screws, flat washers, lock washers and hex nuts supplied. Do not
completely tighten the mounting hardware at this time. It is not necessary to use clamps to hold the front rail to the saw
table. On Delta saws that are equipped with a sheet metal left extension wing, fasten the front rail (C) to the extension
wing using the remaining 3/8-16 x 1-1/4” long flat head screw, lock washer and hex nut supplied through hole (F) in the
front rail

NOTE: On Contractor’s saws made prior to 1988,
the two mounting holes in the front edge of the
saw were threaded. It is necessary to drill out the
threads with a 7/16” drill bit and use the hardware provided as indicated in step 2.
FOR ALL OTHER TABLE SAWS
(Including Delta Models 34-670, 36-380 and 36-600)
3. Raise saw blade (A) Fig. 7. Place a straight edge (B) against right side of saw blade extending out over front of saw
table as shown. Position front rail (C) against front edge of saw table and lightly clamp in place using bar clamps (D). Align
the notch (E) in front rail (C) with right side of saw blade using the straight edge (B) as shown, and tighten bar clamps (D).
