of the tool.
CORRECT USAGE
This tool is designed to be used as a polisher. Read all the
warnings, instructions, indications provided on drawings and

serious injuries.
This tool is not intended to be used for smoothing, metal
brushing and cutting operations. The use of this tool for unintended
applications may cause hazards and injuries to people.
The tool must be used with accessories that have been
specifically designed or recommended by the manufacturer. The

operation.
The rated speed of the accessories must be at least equivalent to
the maximum speed specified on the tool. Using the accessories
at speeds above the rated one, may cause them to break or be
projected into the air.
The external diameter and thickness of the accessories must
match the specifications of the tool. Accessories with incorrect
dimensions cannot be adequately protected or controlled.
The configuration of accessories must match the tool. The use of
accessories that cannot be perfectly fitted on the tool may result in
imbalance, excessive vibrations and in the impossibility of controlling

accessories. Inspect the supporting pads and verify there are no
cracks, tears or excessive wear. If the tool or accessory has
fallen, verify that it is not damaged or install a new accessory.
After inspecting or installing an accessory, test the operation of
the tool at maximum speed and without load for one minute,
keeping at a safety distance. If the accessories are damaged, they
will break during this test.
