A Fig. 29B A NOTE: Leave the rear support extended during all cutting operations. Push the rear support in only when storing the machine. Fig. 29C 13 SIDE SUPPORTS This machine has two side supports to (1) help stabilize the machine, and (2) to help support long or wide workpieces. The supports are located on either side of the table. The machine comes with the supports pushed in (Fig. 29D). To utilize the supports, pull them out to their full length (Fig. 29E). Fig. 29D Fig. 29E GENERAL CUTTING OPERATIONS 1. Your machine has the capacity to cut standard 2 x 4’s lying flat or on edge, at the 45 degree right and left miter angles (Figs. 30A and 30B). 2. A standard 2 x 6 can be cut in the 90 degree straight cut-off position in one pass (Fig. 30C). 3. A standard 4 x 4 can be cut with one pass (Fig. 30D). 4. This machine has the capacity to accurately cut crown moldings and other bevel-type cuts (Fig. 30E). 5. Cutting various sizes of plastic pipe is an easy job with this machine (Fig. 30F). Fig. 30A Fig.30B Fig. 30C Fig. 30D 14 Fig. 30F Fig. 30E BLADE CUTTING ALUMINUM FENCE Aluminum extrusions such as used for making aluminum screens and storm windows can easily be cut with your compound miter saw. When cutting aluminum extrusions, or other sections that can be cut with a saw blade and are within the capacity of the machine, position the material so the blade is cutting through the smallest cross-section (Fig. 31). The wrong way to cut aluminum angles is illustrated in Fig. 32. Be sure to apply a stick wax to the blade before cutting aluminum stock. This stick wax is available at most industrial mill supply houses. The wax provides proper lubrication and keeps chips from adhering to the blade. RIGHT Fig. 31 BLADE FENCE WARNING: NEVER APPLY LUBRICANT TO THE BLADE WHILE THE MACHINE IS RUNNING. WRONG Fig. 32 CUTTING BOWED MATERIAL When cutting flat pieces, first check to see if the material is bowed. If it is, make sure the material is positioned on the table as shown in Fig. 33. If the material is positioned the wrong way (Fig. 34), the workpiece will pinch the blade near the completion of the cut. Fig. 33 Fig. 34 15 CUTTING CROWN MOULDING AA One of the many features of your saw is the ease of cutting crown moulding.The following is an example of cutting both inside and outside corners on 52/38 degree wall angle crown moulding. NOTE: When cutting 45 degree wall angle crown moulding, the following procedure for inside and outside corners is the same with the exception that the bevel position will always be at 30 degrees and the miter position will be 35.25 degrees to the right or left.
