English Prior to Operation • Install the guard and appropriate disc or wheel. Do not use excessively worn discs or wheels. • Be sure the backing and threaded locking flange are mounted correctly. Follow the instructions given in the Grinding and Cutting Accessory Chart. • Make sure the disc or wheel rotates in the direction of the arrows on the accessory and the tool. • Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time. OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories.
