Mounting Wire Cup Brushes and Wire Wheels
(Fig. A)

WARNING: Failure to properly seat the flange/ clamp nut/
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 centre.
1. Place the tool on a table, guard up.
2. Thread the wheel on the spindle by hand.
3. Depress spindle lock button
of the wire wheel or brush to tighten the wheel.
4. To remove the wheel, reverse the above procedure.
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 and locking flange are mounted correctly.
Follow the instructions given in the Accessory and Guard
Applications 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.
