USING WIRE 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.

WARNING!

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.

2.Thread nylon washer onto spindle. Attach wire cup brush onto spindle.

3.Press 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.

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.

2.Thread nylon washer onto spindle. Attach guard and wire wheel brush onto spindle (see Fig. 2 and 3 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 Fig. 9.

3.Press 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.

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.

Using Wire Brushes

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 dam- aged 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).
