H Fig. G Fig. F TO CHECK FOR VERTICAL ALIGNMENT 1. The vertical alignment is set correctly when the lines do not move horizontally (sideways) as the saw head is raised and lowered. If vertical alignment is correct jump to “TO SET LEFT AND RIGHT KERF ADJUSTMENT”. 2. If the vertical alignment needs to be adjusted, begin by backing the left and right kerf adjustment screws one half turn clockwise. Remove the laser unit cover by removing the phillips screw on either side of the cover. (Fig. A). 3. Use the 1/8" hex wrench to turn the left or right vertical alignment set screws. If as the saw head goes from a raised to a lowered position and the laser line moves horizontally away from the blade, turn vertical alignment set screw clockwise to correct. If the laser line moves horizontally towards the blade, turn vertical alignment set screw counterclockwise to correct. (Fig. F) 4. Reinstall cover removed in step 1, and continue to “TO SET LEFT AND RIGHT KERF ADJUSTMENT”. TO SET LEFT and RIGHT KERF ADJUSTMENT 1. Use the 1/8" hex wrench to turn the left or right kerf adjustment screws and set the laser lines to either side of the test cut (Fig. G). To adjust the left line turn the left kerf adjustment screw counter-clockwise to move the line toward the blade and clockwise to move the line away from the blade. To adjust the right line turn the right kerf adjustment screw counter-clockwise to move the line toward the blade and CW to move the line away from the blade. (Fig. H) Observe laser CAUTION label (L) Fig. H. 2. Remove the padlock and use normally. TwinLaser™ MAINTENANCE For best laser performance, perform the following maintenance regularly: 1. DISCONNECT THE MACHINE FROM THE POWER SOURCE. 2. Carefully clean sawdust from each laser lens with a cotton swab Fig. J. Do not use solvents of any kind since they may damage the lens. Avoid touching sharp points of saw blade with your hands or fingers. Dust build-up can block the laser and prevent it from accurately indicating the line of cut. 3. Remove blade from saw and clean pitch build-up from blade Fig. K Pitch build-up can block the laser and prevent it from accurately indicating the line of cut.

Before cutting, make certain the cutting arm and table area are at their correct settings and firmly locked in place. 2. Before cutting, determine that the workpiece is the right size for the saw. 3. Place the workpiece on the table and hold or clamp it firmly against the fence. If the size of the workpiece causes your hand to be inside the table hazard zone (see section “TABLE HAZARD ZONE” SEE FIG. 17), use a clamp to secure the workpiece. 5. For best results, cut at a slow, even cutting rate. 6. Never attempt any freehand cutting (wood that is not held firmly against the fence and table). AUXILIARY WOOD FENCE 4. When performing multiple or repetitive cut-off operations that result in small cut-off pieces (one inch or less), the saw blade can catch the cut-off pieces and project them out of the machine or into the blade guard and housing, possibly causing damage and/or injury. In order to limit the possibility of personal injury or blade guard damage, an auxiliary wood fence can be mounted to your saw as follows: Holes are provided in the fence to attach an auxiliary fence (A) and (B) Fig. 31. This auxiliary fence is constructed of straight wood approximately 1/2” thick by 3” high by 16 inches long as shown at (B); and 1/2” thick by 5” high by 17” long (A) Fig. 31. NOTE: The auxiliary fence is used only with the saw blade in the 0° bevel position (90°) to the table. The auxiliary fence must be removed for all bevel cuts (blade tilted). CUTTING ALUMINUM Aluminum extrusions (aluminum screens and storm windows) can easily be cut with your 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, as shown in Fig. 32. The wrong way to cut aluminum angles is illustrated in Fig. 33. Be sure to apply a stick wax (similar to Johnson’s stick wax #140) to the blade before cutting any aluminum stock. This stick wax is available at most industrial mill supply houses. The stick wax provides proper lubrication and keeps chips from adhering to the blade. NEVER APPLY LUBRICANT TO THE BLADE WHILE THE BLADE IS RUNNING. CUTTING BOWED MATERIAL 1. 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. 34. 2. If the material is positioned the wrong way, as shown in Fig. 35, the workpiece will pinch the blade near the completion of the cut.
