ADJUSTMENTS WARNING: Before performing any adjustment, make sure the tool is unplugged from the power supply and the switch is in the OFF position. Failure to heed this warning could result in serious personal injury. WARNING: Never tie the lower blade guard in a raised position. Leaving the blade exposed could lead to serious injury. 0° BEVEL STOP See Figure 24, page 18. The saw has a 0° bevel stop that has been factory adjusted to assure 0° angle of the saw blade when making 0° cuts. To check 0° bevel stop: Unplug the saw. Place the saw in an upside down position on a work- bench. Check the squareness of the saw blade plate to the base of the saw using a combination square. To adjust 0° bevel stop: Unplug the circular saw. Loosen bevel adjustment knob. Loosen hex nut securing adjusting screw. Turn adjusting screw and adjust base until square with saw blade. Tighten hex nut and bevel adjustment knob securely. WARNING: Attempting a bevel cut without having the bevel adjustment knob securely tightened can result in serious injury. CHECKING/ADJUSTING THE LASER ALIGNMENT See Figure 25, page 19. 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 can result in hazardous radiation exposure. Unplug the saw. REMOVE the blade before adjusting the laser. Clamp a straight edge to the straight side of a workpiece. Square the long edge of the saw base against the straight edge. With a pencil, mark the workpiece in front of the far right notch on the saw's base. Slide the saw along the straight edge and mark the notch 10 - 12 in. from the first mark. Draw a guideline to connect the two marks. Slide the saw back to the starting position so that the entire guideline is visible. Connect the saw to a power supply. Depress and hold the switch until the laser turns on. NOTE: The laser will activate without the saw motor running. The laser beam should align with the notch in the saw base and the guideline you drew on the workpiece. If the laser beam is out of adjustment, use a 1/8 in. flat head screwdriver to turn the laser adjusting screw until the beam aligns with the guideline. Slowly turn the screw counterclockwise to adjust the laser to the left, or clockwise to adjust the laser to the right. ADJUSTING THE DEPTH LOCK LEVER See Figure 26, page 19. Over time, due to wear, the depth lock lever may move from its original setting. If the lever prematurely contacts any part of the saw during tightening and loosening, adjust the lever by following these steps: Unplug the saw. Pull depth lock lever upward to release. Pull saw base down to the minimum depth of cut position, then push the depth lock lever down to secure. Insert a flathead screwdriver into the space between the lock nut and the E-ring. Remove the E-ring. Note the position of the lever on the nut. Slide the depth lock lever off the lock nut. The lock nut has six flat sides. Rotate the depth lock lever one "flat" counter clockwise around the nut. Then slide it back into place. Push the E-ring back into the groove on the lock nut until it snaps into place. Take care that the E-ring does not pop off the lock nut. Loosen the depth lock lever and return the base to the full depth of cut position and lock the depth setting by pushing downward on the depth lock lever. The base should be locked securely in position when locked and be free to move when released. 13 - English
