MAINTENANCE TO REMOVE THE BLADE Fig. 37a-37c � WARNING: To reduce the risk of injury, always unplug the tool before removing or installing a blade. 1. Unplug the tool. 2. Raise the saw arm. 3. Loosen the screw with the Phillips screwdriver on the end of the blade wrench (included) as illustrated in Fig. 37a. 4. Lift and hold the lower blade guard, and rotate the blade-screw guard to expose the threaded blade screw. 5. Press and hold the spindle-lock button, and rotate the blade at the same time until it locks into position. 6. Use the hex end blade wrench (included) to turn the threaded blade screw clockwise. Remove the threaded blade screw. 7. Remove the outer blade flange and the blade. Wipe the blade flanges and spindle to remove any dust and debris. TO INSTALL THE BLADE Fig. 37d � WARNING: Do not use thin-kerf blades. Thin-kerf blades can deflect and contact the guard, which can cause injury to the operator. 1. Unplug the saw. 2. Ensure that the inner blade flange (Fig. 37b) is properly installed. 3. Match the arrow on the blade with the arrow on the upper blade guard. Make sure that the teeth of the blade are pointing downward. Install the selected blade by sliding the blade into the upper blade guard and then placing the blade in position. 4. Install the outer blade flange (Fig. 37b). � WARNING: Make sure that the flat side of the blade flange is placed against the blade. 5. Press and hold the spindle-lock button, and use the blade wrench (included) to turn the blade screw counter-clockwise until the lock engages. Securely tighten the blade screw. 6. Rotate the blade-screw guard into position, and use the Phillips screwdriver end of blade wrench to securely tighten the screw by turning it clockwise. Remove the blade wrench, and store it safely. Wrench storage is provided in the miter saw base. 7. Make sure that the spindle-lock button is released so the blade will rotate freely. 8. Lower the saw arm, and check the clearance between the blade and the miter table. The blade should rotate freely.
