for use.
ALWAyS hold the tool firmly with one hand on the motor housing and the other on the
side handle. Turn the tool on and then apply the wheel or disc to the workpiece. The key
to efficient operation begins by controlling the pressure and surface contact between
grinding wheel and the workpiece.
flat surfaces are usually best ground by keeping the edge of the wheel at an angle of 5
to 15 degrees. Maintaining the proper angle of 5 to 15 degrees by tilting the grinder and
continuously moving the grinder back and forth or up and down over the work area. Keep
the grinder moving to avoid removing a excessive amount of material from one area.
use just enough pressure to keep the tool from chattering or bouncing; normally the
weight of the tool alone is adequate for most grinding jobs. Where there is a chance that
the
grinding wheel may get snagged by the workpiece, such as loose bolts or jagged edges,
causing loss of tool control, use lighter pressure.
OPERATION WITH WIRE BRUSHES:

and brush bristles will fly off, going great distances with extreme force. The potential for
serious injury exists. To protect against this hazard, the operator and others in the work
area
must wear protective clothing and safety goggles. Wearing a full face mask over safety
glasses with side shields is highly suggested.

adjusting, adding accessories, or checking a function on the tool.
Do not use a brush that is damaged or is out of balance. use of a damaged brush
increases the potential for injury from contact with broken brush wires.
Wire brushes designed for grinder use are available in a variety of shapes, sizes, and
wire types. unlike grinding wheels which are held in place inner and flange washers,
wire brushes screw onto the spindle; for this grinder, wire brushes utilizing a 5/8"-11unc
thread are required. The flat brush styles must also be of a diameter and thickness which
allows their use with the guard in place.
To install the wire brush, unplug the tool and place it upside down allowing easy access
to the spindle. Remove any accessories on the spindle, then thread the wire brush onto
the spindle and tighten securely with an adjustable wrench while depressing the spindle
lock.
Perform wire brush operations in a fashion similar grinding as described in the previous
section. Tip the grinder from 5 to 15 degrees and allow the weight of the tool to remove
material as desired. excessive pressure causes premature wire breakage and bending
over of the wires.
In normal wire brushing operations, the material being removed
Always be sure that the tool is switched off and unplugged before
