2.During operation, lower clamp (A) Fig. 23, by depressing lock lever (D), until the bottom of the clamp

(A) lightly contacts top of workpiece (F). IMPORTANT: When lowering clamp (A) make certain cam lever

(G) is in the up position as shown.

TILTING CUTTINGHEAD FOR BEVEL CUTTING

CAUTION: DISCONNECT THE MACHINE FROM THE POWER SOURCE.

1.The cuttinghead of your compound miter saw can be tilted to cut any bevel angle from a 90 degree straight cut-off to a 45 degree left bevel angle by loosening bevel lock handle (A) Fig. 25, tilting cuttinghead (B) to the desired angle, and tightening lock handle (A).

2.Positive stops are provided to rapidly position the saw blade at 90 and 45 degrees to the table. Refer to the

section of this manual titled Adjusting 90 and 45 degree bevel positive stops. The bevel angle of the cutting arm is determined by the position of the pointer (C) Fig. 26, on scale (D).

3. In addition, an indicator (E) Fig. 26, is provided on the bevel scale at the 33.9 degree bevel angle for cutting crown moulding. Refer to the CUTTING CROWN MOULDING section of this manual.
