OPERATION CUTTING WITH YOUR Compound MITER SAW WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. WARNING: When using a work clamp or C-clamp to secure your workpiece, clamp workpiece on one side of the blade only. The workpiece must remain free on one side of the blade to prevent the blade from binding in workpiece. The workpiece binding the blade will cause motor stalling and kickback.
OPERATION Note: You can quickly locate 0°, 15°, 22-1/2°, left or right, 31.62° and 45° left or right as you rotate the control arm. The miter table will seat itself in one of the positive stop index points, located in base. miter CUT Push the miter lock lever down to lock the miter table. 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.
OPERATION 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. Compound Miter Cut 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 35.

OPERATION CUTTING COMPOUND MITERS To aid in making the correct settings, the compound angle setting chart below has been provided. Since compound cuts are the most difficult to accurately obtain, trial cuts should be made in scrap material, and much thought and planning made, prior to making the required cut.

OPERATION cutting crown molding When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one angle changes the other angle as well. Keep in mind that the angles for crown molding are very precise and difficult to set. Since it is very easy for these angles to shift, all settings should first be tested on scrap molding. Also most walls do not have angles of exactly 90°, therefore, you will need to fine tune your settings.

ADJUSTMENTS POSITIVE STOP ADJUSTMENTS WARNING: See Figure 39. Note: These adjustments were made at the factory and normally do not require readjustment. To adjust: Unplug the saw. Loosen the bevel lock knob by turning the knob counterclockwise. Square the blade to the miter table as described in the Assembly section of this manual. If the blade is out of square, adjust by tightening or loosening the positive stop adjustment screw. Retighten bevel lock knob. Recheck blade-to-table alignment.
ADJUSTMENTS laser adjustment screw Danger: Laser radiation. Avoid direct eye contact with light source. WARNING: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. TO ADJUST THE LASER GUIDE See Figure 40. Use the work clamp or a C-clamp to secure a piece of scrap wood. Plug the saw into the power source and make a slight cut to score the wood. Fig.
