REMOVING "HEELING" IN SAW CUT Even though the cuttinghead travel may be perfectly aligned at 90 degrees to the fence, the blade itself may not be 90 degrees or square with the fence, (Fig. 42). This condition is known as "heeling."To check and adjust: DISCONNECT MACHINE FROM POWER SOURCE. 1. Cross-cut a board and see on which side of the cut board saw teeth marks appear. Fig. 42 2. If saw teeth marks appear on the right side, the back end of the saw blade must be shifted toward left side. 3. Loo

ADJUSTING BLADE GUARD DISCONNECT MACHINE FROM POWER SOURCE. On all ripping and plowing operations, the back part of the blade guard is lowered so that it just clears the material. This will prevent the material from being lifted off the table. Also, lower the kickback rod (A) Fig. 46, so that the kickback fingers are 1/8" below surface of material. The kickback fingers will then come into contact with the material preventing "kickback." Adjust dust elbow (B) Fig. 46 to direct sawdust to rear of
