MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
WARNING: To reduce the risk of serious personal injury,
turn tool off and remove the battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can cause 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.
NOTICE: 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 (FIG. 16)
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 (refer to Precautions To Take When
Sanding Paint).
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 Type 1/Type 41

MOUNTING CLOSED (TYPE 1) GUARD (FIG. 17, 18)
WARNING: To reduce the risk of serious personal injury,
turn tool off and remove the battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can cause injury.
