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. When using a Type A (cut-off), or Type B
(grinding) wheel guard with a wheel-type wire brush with a
thickness greater than the maximum thickness as specified in
the Accessory and Guard Applications Chart , the wires
may catch on the guard leading to breaking of the wires.
Wire cup brushes or wire wheels install directly on the threaded
spindle without the use of locking flange. Use only wire brushes
or wheels provided with a M14 threaded hub. These accessories
are available at extra cost from your local D
authorised D WALT service centre.
