OPERATION
TO COMPOUND MITER CUT
See Figure 38.
A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuts.
To make this type of cut the control arm on the miter table must be rotated to the correct angle and the saw arm must be tilted to the correct bevel angle. Care should always be taken when making compound miter setups due to the interaction of the two angle settings.
Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting.
It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.
NOTE: It may be necessary to adjust or remove the sliding miter fence to insure proper clearance prior to making the cut.
Make sure the slide lock knob is tightened securely.
Raise saw arm to its full height.
Lift the miter lock lever to unlock. Rotate the miter table until the pointer aligns with the desired angle on the miter scale.
NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, 45°, and 60° left or right by spinning the miter thumbwheel up. The lock plate will seat itself in one of the positive stop notches, located in the miter table base.
Push the miter lock lever down to lock the miter table.
Lift the bevel lock lever and move the saw arm to the left or right to the desired bevel angle.
Once the saw arm has been set at the desired angle, securely tighten the bevel lock lever.
Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See Figures 47 - 48.
When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 40.
Align the cutting line on the workpiece with the edge of saw blade.
Grasp the stock firmly with one hand and secure it against

Before turning on the saw, perform a dry run of the cut- ting operation to make sure that no problems will occur when the cut is made.
Make a test cut in scrap material.
Grasp the saw handle firmly. Depress the switch lock with thumb then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
Slowly lower the blade into and through the workpiece.
Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece and removing the workpiece from the miter table.
