NOTE: The piece of crown moulding used for the outside corner will always be on the right hand side of the blade, as shown at (A) Fig. 47. The piece of crown moulding used for the inside corner will always be on the left hand side of the blade, as shown at (B) Fig. 47. Note that the standard equipment work clamp

(E)is being used to hold the workpiece in position.

4.To make the matching halves of the inside and outside corners, simply rotate the table to the 3158 degree left miter position.

NOTE: A positive stop is provided to find this angle quickly.The saw blade is already tilted to the 3378 degree bevel position from the previous cut.

5.Place the crown moulding on the table with the W ALL EDGE of the crown moulding against the fence and make the cut. Again, the piece of crown moulding used for the outside corner will always be on the right side of the blade, as shown at (C) Fig. 48. The piece of crown moulding used for the inside corner will always be on the left side of the blade, as shown at (D) Fig. 48. Again, the standard equipment work clamp (E) is being used to hold the workpiece in position.

6.Fig. 49 illustrates the two outside corner pieces; (A) being the piece cut at (A) Fig. 47, and (C) being the piece cut at (C) Fig. 48.

7.Fig. 50 illustrates the two inside corner pieces; (B) being the piece cut at (B) Fig. 47, and (D) being the piece cut at (D) Fig. 48.

MAINTENANCE

CHANGING THE BLADE

W ARNING: USE ONLY CROSS-CUTTING SAW BLADES. WHEN USING CARBIDE TIPPED BLADES BE SURE THE HOOK ANGLE IS 5 DEGREES OR LESS. DO NOT USE BLADES WITH DEEP GULLETS AS THEY CAN DEFLECT AND CONTACT GUARD. USE ONLY BLADES RATED FOR OPERATION OF AT LEAST 6000 RPM WITH 58" ARBOR HOLES.

1.DISCONNECT THE SAW FROM THE POWER SOURCE.

2.Using the special wrench (A) Fig. 51, supplied, loosen screw (B) to free arbor cover (C).

3.Rotate arbor cover (C) Fig. 52, and lower guard (D) to the up position, as shown.
