Changing or Installing a New Saw Blade (Fig. A, C-E) WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change accessories or make any adjustments. CAUTION: • Never depress the spindle lock button while the blade is under power or coasting. • Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product with this miter saw. Removing the Blade 1. Unplug the saw. 2. Raise the arm to the upper position and raise the lower guard 4 as far as possible. 3. Loosen, but do not remove guard bracket screw 36 until the bracket can be raised far enough to access the blade screw 23 . Lower guard will remain raised due to the position of the guard bracket screw. 4. Depress the spindle lock button 24 while carefully rotating the saw blade by hand until the lock engages. 5. Keeping the button depressed, use the other hand and the 6 mm hex wrench provided 16 to loosen the blade screw. (Turn clockwise, left-hand threads.) Fig. C English 3. Assemble the outer blade clamp onto the spindle. 4. Install the blade screw 23 and, engaging the spindle lock, tighten the screw firmly with the 6 mm hex wrench provided. (Turn counterclockwise, left-hand threads.) NOTE: When using blades with a 5/8" (15.88 mm) diameter blade hole, the blade adapter will not be used and should be stored in a safe place for future use. 5. Return the guard bracket to its original position and firmly tighten the guard bracket screw 36 to hold bracket in place. WARNING: • The guard bracket must be returned to its original position and the screw tightened before activating the saw. • Failure to do so may allow the guard to contact the spinning saw blade resulting in damage to the saw and severe personal injury. Miter Scale Adjustment (Fig. F) Place a square against the saw's fence and blade. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measurement.) Unlock miter lock knob 5 and swing the miter arm until the miter detent latch locks it at the 0˚ miter position. Do not lock miter lock knob. If the saw blade is not exactly perpendicular to the base fence 18 , loosen the three miter scale screws 8 that hold the miter scale 7 to the base and move the scale/miter arm assembly left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the three screws. Pay no attention to the reading of the miter pointer at this point. Fig. F 36 16 23 Fig. D 24 6. Remove the blade screw 23 , outer blade clamp 25 , and blade 26 . The inner blade clamp 27 , and if used, the 1" (25.4 mm) blade adapter, may be left on the spindle. NOTE: For blades with a blade hole of 5/8" (15.88 mm), the 1" (25.4 mm) blade adapter is not used. Fig. E 26 25 7 5 Miter Pointer Adjustment (Fig. A, F, G) Unlock miter lock knob 5 and squeeze the miter detent latch 6 to move the miter arm to the zero position. Unlock the miter lock knob to allow the miter detent latch to snap into place as you rotate the miter arm toward zero. Observe the pointer 28 and miter scale 7 through the viewing opening shown in Figure G. If the pointer does not indicate exactly zero, loosen the pointer screw, adjust the pointer to 0˚ and retighten. Fig. G 23 7 28 Bevel Square to Table (Fig. A, H) To align the blade square to the rotary table, lock the arm in the down position. Place a square against the blade taking care to not have the square on top of a tooth. Loosen the bevel lock knob 5 and ensure the arm is firmly against the 0° bevel stop. Move the 0° bevel stop adjusting screw 19 as necessary so that the blade is at 0° bevel to the table. Ensure the bevel override 27 levers are pushed inward to obtain an accurate adjustment. Installing a Blade 1. Unplug the saw. 2. With the arm raised, the lower guard held open and the guard bracket raised, place the blade on the spindle, onto the blade adapter [if using a blade with a 1" (25.4 mm) diameter blade hole] and against the inner blade clamp with the teeth at the bottom of the blade pointing toward the back of the saw. 5
