SAFETY SETUP Maintenance and Servicing Procedures not specifically explained in this manual must be performed only by a qualified technician. TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Turn the Power Switch of the tool off and unplug the tool from its electrical outlet before performing any procedure in this section. TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use. Cleaning, Maintenance, and Lubrication 1. BEFORE EACH USE, inspect the general condition of the tool. Check for: • loose hardware, • misalignment or binding of moving parts, • cracked or broken parts, • damaged electrical wiring, and • any other condition that may affect its safe operation. 2. AFTER USE, wipe external surfaces of the tool with clean cloth. 3. WARNING! If the supply cord of this power tool is damaged, it must be replaced only by a qualified service technician. Checking and Calibrating the Fence The Fence holds the workpiece in a fixed position while the Table and or the blade assembly are adjusted in a miter or bevel angle. To make accurate cuts, the Fence must be perpendicular (at a 90º angle) to the Saw Blade. 1. Before beginning work, make a test cut on scrap material with the Table set at 90º. 4. Remove Nut (9) from the front of the left side fence extension, and remove the left side Extension Lock (15) to allow access to the left side Fence Adjusting Screw (20). Remove this Extension Lock (15) 2. Check the cut with an accurate square. You can also reverse the two pieces, hold the cut ends together, and hold a good straight edge along the side of the pieces. 3. If either test reveals that the cut is not a true 90º angle, adjust the Fence before beginning work. Fence Adjusting Screw (20) If Fence needs adjustment: 1. First unplug the tool. 2. Lower the blade assembly and lock it in place using the Locking Pin. 3. Lay a carpenter's square on the table with one edge along the blade and the other along the Fence. Any inaccuracy should be visible. NOTE: The square must contact the surface of the blade, not the teeth, for an accurate reading. Figure E: Left Fence Adjusting Screw Access 5. The Fence is held in place with a Fence Adjusting Screw (20) at each end. Loosen the bolts slightly, and gently tap the Fence into position using a soft mallet. Tighten the Bolts and make another test cut. Repeat the process until the Fence is adjusted accurately. 6. Once the Fence is accurately adjusted, tighten the Bolts firmly in place and reinstall the Extension Lock (15). Recheck one last time, then proceed to work.
