OPERATION

SUPPORTING LONG WORKPIECES

See Figures 40 - 41.

Long workpieces need extra supports. Supports should be placed along the workpiece so it does not sag. The support should let the workpiece lay flat on the base of the saw and miter table during the cutting operation. Use the optional work clamp or a C-clamp to secure the workpiece.

NOTE: When making a compound miter cut as shown in figure 40, it may be necessary to adjust or remove the sliding miter fence to insure proper clearance prior to mak- ing the cut.
