USING WIRE BRUSHES
Installing Wire Cup Brushes (Fig. 8)
Selecting Wire Brushes
Wire brushes are useful for removing rust, scale, burrs, weld slag, etc.
A wide variety of wire brushes are available for many applications.
1. Unplug tool and place it upside down on a level surface. Remove
any accessories from spindle.
NOTE: Never use a guard with a wire cup brush.
2. Thread flange and nylon washer onto spindle. Attach wire cup
brush onto spindle.
3. Press in the spindle lock button while tightening brush with a wrench
(not provided with tool).
4. To remove wire cup brush, unplug tool and reverse procedure.

1. Do not wear loose clothing when using wire brushes. The wires
may catch on loose clothing and pull the clothing into the moving
parts.
2. Firmly grasp rear handle and side handle before starting and while
using tool. Always test the wire brush for balance and loose or
damaged wires by running tool at no load speed for at least one
minute before applying it to your work.
3. When applying brush to work, avoid using too much pressure. This
causes over-bending of wires and heat build-up resulting in prema-
ture wire breakage, rapid dulling and reduced brush life.
Instead of using more pressure, try a wire wheel brush with more
aggressive cutting action (increased wire size, decreased wire
length or different brush type, i.e. knot type instead of crimped wire
type).
1. Unplug tool and place it upside down on a level surface. Remove any
accessories from spindle.
2. Thread flange and nylon washer onto spindle. Attach guard and
wire wheel brush onto spindle (see Fig. 4 for attaching guard).
Position the guard in the location which offers best control and
guard protection. For operating zones that provide maximum protec-
tion for the operator, see "Grinding".
3. Press in the spindle lock button while tightening brush with a wrench
(not provided with tool).
4. To remove wire wheel brush and guard, unplug tool and reverse
procedure.

Using Wire Brushes
Everyone in the area must wear protective clothing and
safety goggles or face shields. Fatigued wires and residue
will fly off the brush with considerable force, causing the
potential for serious injuries.
WARNING!
Because the wires on wire wheel brushes are directed
towards the operator, a Type 27 guard must be used to
protect the operator when fatigued wires break.
WARNING!
Never exceed Maximum Safe Operating Speed of the brush.
Do not use a damaged brush or one which is functioning
improperly (throwing wires, out-of-balance, etc.). These
conditions increase the possibility of further brush failure
and possible injury. Discard and replace damaged brushes
immediately.
WARNING!
