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 page 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.
Figure B
- Open the guard latch (8a), and align the lugs on the guard (8) with the
slots on the gear case cover (9).
2. Push the guard down until the guard lugs engage and rotate freely in the groove on
the gear case hub.
3. With the guard latch open, rotate the guard into the desired working position. The
guard body should be positioned between the spindle and the operator to provide
maximum operator protection.
4.
Figure C
- Close the guard latch (8a) to secure the guard on the gear case. You
should not be able to rotate the guard by hand when the latch is closed. Do not
operate the grinder with a loose guard or the guard latch in open position.
5. To remove the guard, open the guard latch, rotate the guard so that the lugs and slots
are aligned and pull up on the guard.
