USING WIRE BRUSHES
Installing Wire Cup Brushes
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 ange 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 premature
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 ange 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 protection 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 y 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.
