Do not use damaged accessories. Before use, inspect all of the accessories. Inspect the supporting
pads and verify that there are no cracks, tears or excessive wear. If the tool or accessory has been
dropped, verify that it is not damaged or install a new accessory. After inspecting or installing an ac-
cessory, test the operation of the T-21 DA at maximum speed and without load for one minute, keeping
at a safe distance. If the accessories are damaged, they will break during this test.
SAFETY WARNING APPLICABLE TO POLISHING OPERATIONS
Verify that no loosened part of the polishing tool shroud or the locking ties can rotate freely. Safely

operator’s fingers or get caught by the work piece being machined.
