Black & Decker 90528012 To SET Kerf Adjustment, Laser Maintenance, General Cutting Operations

3.Use the 1/8 in. hex wrench to turn the vertical alignment set screws (Fig. E). If you move the cutterhead from the raised to the lowered position and the laser line moves horizontally away from the blade, turn the vertical alignment set screw clockwise to correct. If the laser line moves horizontally toward the blade, turn the vertical alignment set screw counter-clockwise to correct. (Fig. F)

4.Reinstall the cover removed in step 2.

CAUTION: Never turn the brass hex nut in Fig. E.

TO SET KERF ADJUSTMENT

1.Use the 1/8 in. hex wrench (A) Fig. H to turn the kerf adjustment screw that sets the laser line to either side of the test cut (Fig. G). To adjust the line, turn the kerf adjustment screw counter- clockwise to move the line toward the blade and clockwise to move the line away from the blade.

2.Remove the padlock. The laser miter saw is ready for normal use.

LASER MAINTENANCE

For best laser performance, perform the following maintenance regularly:

1.Carefully clean sawdust from each laser lens (A) Fig. I with a cotton swab (B). Do not use solvents of any kind since they may damage the lens. Avoid touching sharp points of the saw blade with your hands or fingers. Dust build-up can block the laser and prevent it from accurately indicating the line-of-cut.

2.Remove the blade from the saw and clean pitch build-up from the blade (Fig. J) Pitch build-up can block the laser and prevent it from accurately indicating the line-of-cut.

GENERAL CUTTING OPERATIONS

1.Your machine has the capacity to cut standard 2 x 4’s, lying flat or on edge, at the 45° right and left miter angles (Fig. A1 & A2).

2.A standard 2 x 6 can be cut in the 90° straight cut-off position in one pass (Fig. A3).

3.Cutting a standard 4 x 4 can be accomplished with one pass (Fig. A4).

4.This machine has the capacity to accurately cut crown moldings

and other bevel-type cuts (Fig. A5).

5.Cutting various sizes of plastic pipe is an easy job with this machine (Fig. A6). Material must be CLAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when making angle cuts.

BODY AND HAND POSITION (FIG. A7 & A8)

Proper positioning of your body and hands when operating the miter saw will make cutting easier, more accurate and safer. (Fig. A7) Never place hands near cutting area. Place hands no closer than 6 in. (152.4 mm) from the blade. Hold the workpiece tightly to the table and the fence when cutting. Keep hands in position until the trigger has been released and the blade has completely stopped. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS SHOWN IN FIGURE A8. Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard louvers when following a pencil line.

CUTTING ALUMINUM

Aluminum extrusions such as used for making aluminum screens and storm windows can easily be cut with your compound miter saw when fitted with a blade recommended for this material. The blade supplied with this saw is not recommended for cutting aluminum. 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. 32). The wrong way to cut aluminum angles is illustrated in Fig. 33. 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.
