WARNING: Failure to properly seat the flange/ clamp nut/
wheel could result in serious injury (or damage to the tool
or wheel).

CAUTION: To reduce the risk of personal injury,
wear work gloves when handling wire brushes and
wheels. They can become sharp.

Be sure the threaded locking flange are mounted correctly.
Follow the instructions given in the Accessory and Guard
Application 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,
on
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
