(Fig.A)

WARNING: Failure to properly seat the brush/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.

CAUTION: To reduce the risk of damage to the tool,
wheel or brush must not touch guard when mounted
or while in use. Undetectable damage could occur to the
accessory, causing wires to fragment from accessory wheel
orcup.
Wire cup brushes or wire wheels install directly on the
threaded spindle without the use of flanges. Use only wire
brushes or wheels provided with a threaded hub. These
accessories are available at extra cost from your local dealer
or authorised servicecenter.

NOTICE: To reduce the risk of damage to the tool, properly
seat the wheel hub before turning the toolon.
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, 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
and run the power tool at maximum no-load speed for one
minute. Damaged accessories will normally break apart
during this testtime.
