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 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, and tear or excess
wear. 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.
