Prior to Operation
• Install the guard and appropriate disc or wheel. Do not
use excessively worn discs or wheels.
• Be sure the backing flange and the threaded locking
flange are mounted correctly. Follow the instructions
given in the Accessories 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, hold the tool in a well protected area, 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.
