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 inch-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
WARNING: To prevent accidental operation, turn off and unplug tool before
performing the following operations. Failure to do this could result in serious
personal injury.
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 brushing paint as when
sanding paint (see pages 12 and 13).
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. Figure N - 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 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 page 9 for more information.
MOUNTING CLOSED (TYPE 1) GUARD
WARNING: To prevent accidental operation, turn off and unplug tool before
performing the following operations. Failure to do this could result in serious
personal injury.
1. Open the guard latch (10), and align the arrow on the guard (9) with the arrow on the
hub (11). This will align the lugs with slots on the gear case cover. Position the guard
facing backward.

2. Push the guard down until the guard lug engages and rotates freely in the groove on
the gear case hub.
3. Rotate guard (9) into desired working position. The guard body should be positioned
between the spindle and the operator to provide maximum operator protection.
4. Close the guard latch to secure the guard on the gear case cover. You should be
unable to rotate the guard by hand when the latch is in closed position. Do not
operate grinder with a loose guard or clamp lever in open position.
5. To remove the guard, open the guard latch, rotate the guard so that the arrows are
aligned and pull up on the guard.
NOTE: The guard is pre-adjusted to the dia met er of the gear case hub at the factory. If,
after a period of time, the guard becomes loose, tighten the adjusting screw (12) with the
clamp lever in the closed position with guard installed on the tool.
CAUTION: Do not tighten adjusting screw with clamp lever in open position.
Undetectable damage to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
WARNING: To prevent accidental operation, turn off and unplug tool before
performing the following operations. Failure to do this could result in serious
personal injury.
CAUTION: Matching diameter threaded backing flange and clamp nut (included with
tool) must be used for cutting wheels.
1. Place the unthreaded backing flange on spindle with the raised section (pilot) facing
up. The raised section (pilot) on the backing flange will be against the wheel when
the wheel is installed.
2. Place the wheel on the backing flange, centering the wheel on the raised section
(pilot).
3. Install the threaded clamp nut with the raised section (pilot) facing away from the
wheel.
4. Depress the spindle lock button and tighten clamp nut with included wrench.
5. To remove the wheel, grasp and turn the wheel while depressing the spindle lock button.
USING CUTTING WHEELS
WARNING: Do not use edge grinding/cutting wheels for surface grinding applications
because these wheels are not designed for side pressures encountered with surface
grinding. Wheel breakage and injury may result.
1. Allow tool to reach full speed before touching tool to work surface.
2. Apply minimum pressure to work surface, allowing tool to operate at high speed.
Cutting rate is greatest when the tool operates at high speed.
3. Once a cut is begun and a notch is established in the workpiece, do not change the
angle of the cut. Changing the angle will cause the wheel to bend and may cause
wheel breakage.
4. Remove the tool from work surface before turning tool off. Allow the tool to stop
rotating before setting it down.
Maintenance
CLEANING
WARNING: Blowing dust and grit out of the motor housing using compressed air is a
necessary maintenance procedure. Dust and grit from metal grinding often accumulate
on interior surfaces and could create an electrical shock hazard if not cleaned out.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
Use only mild soap and a damp cloth to clean the tool. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
