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
5˚-10˚
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 backward 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.
