Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. Use only wire brushes or wheels
provided with a 5/8"-11 threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
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.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
WARNING: To reduce the risk of serious personal injury, turn
tool off and and remove battery pack before making any adjust-
ments or removing/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: To reduce the risk of damage to the tool, properly seat
the wheel hub before turning the tool on.
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 brushing
paint as when sanding paint (see page 20).
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, two-sided cutting wheel guard is included
with this tool and is re quired when using cutting wheels. Fail ure to
use proper flange and guard can re sult in injury resulting from
wheel breakage and wheel contact. See pages 14 and 15 for more
information.
