1. Allow the tool to reach full speed before touching tool to the work surface.
2. Apply minimum pressure to work surface, allowing the tool to operate at high
speed. Sanding rate is greatest when the tool operates at high speed.
3. Maintain a 5˚ to 15˚ angle between the tool and work surface. The sanding
disc should contact approximately one inch of
work surface.
4. Move the tool constantly in a straight line to
prevent burning and swirling of 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.
5. Remove the tool from work surface before turning tool off. Allow the tool to
stop rotating before laying it down.
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 14M2 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 and unplug the tool before making any adjustments or
removing or installing attachments or accessories. Before reconnecting the tool,
turn the switch on and off as previously described to ensure that the tool is off.
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.
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 sur-
face. 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 not included with this tool but
is required when using cutting wheels. Failure to use proper flange and guard can re-
sult in injury resulting from wheel breakage and wheel contact. See page 7 for more
information.
MOUNTING CLOSED (TYPE 1) GUARD
CAUTION: Turn off and unplug the tool before making any adjustments or
removing or installing attachments or accessories. Before reconnecting the tool,
turn the switch on and off as previously described to ensure that the tool is off.
