Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder spin-
dle without the use of flanges. Use only wire brushes or wheels pro-
vided with a 5/8"-11 threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
CAUTION: 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.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
1. Thread the wheel on the spindle by hand.
2. Depress spindle lock button and use a wrench on the hub of the
wire wheel or brush to tighten the wheel.
3. To remove the wheel, reverse the above procedure.
CAUTION: Failure to properly seat the wheel hub before turning
the tool on may result in damage to tool or wheel.
USING WIRE CUP BRUSHES AND WIRE WHEELS
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
NOTE: The same precautions should be taken when wire brushng
paint as when sanding paint (see page 15).
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to work surface, allowing the tool to
operate at high speed. Material removal rate is greatest when
the tool operates at high speed.

3. Maintain a 5˚ to 10˚ angle between the
tool and work surface for wire cup brushes.
4. Maintain contact between the edge of the
wheel and the work surface with wire
wheels.
5. Continuously move the tool in a forward
and back motion to avoid creating gouges in the work surface.
Allowing the tool to rest on the work surface without moving, or
moving the tool in a circular motion causes burning and swirling
marks on the work surface.
6. Remove the tool from the work surface before turning the tool
off. Allow the tool to stop rotating before setting it down.
CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.
Mounting and Using Cutting
(Type 1) Wheels
Cutting wheels include diamond wheels and abrasive discs.
Abrasive cutting wheels for metal and concrete use are available.
Diamond blades for concrete cutting can also be used.
WARNING: A closed, 2-sided cutting wheel guard is included
with this tool and is required when using cutting wheels. Failure to
use proper flange and guard can result in injury resulting from
wheel breakage and wheel contact. See pages 10 and 11 for more
information.
MOUNTING CLOSED (TYPE 1) GUARD
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
1. Open the guard latch (J), and align the arrow on the guard (K)
with the arrow on the hub (L). This will align the lugs with slots
on the gear case cover. Position the guard facing backward.
