WARNING!

A Type “1” guard must be installed when using

acut-off wheel to provide maximum protection for the operator if the wheel should break.

Using Cut-Off Wheels (Fig. 12)

Type “1” Cut-Off Wheels are suited for small cut-off and shallow notch- ing operations only.

1.Firmly grasp body of tool and side handle before starting and while using tool. Allow wheel to come to full speed before starting.

2.When using a cut-off wheel, hold Sander/Grinder as shown, using only the edge of the wheel.

Fig. 12

3.Control pressure and surface contact between disc and workpiece. Too much pressure slows cutting speed.

WARNING!

Using the face of a Cut-Off Wheel (as in grinding) will cause the Wheel to crack and break, resulting in serious personal injury.

Installing Wire Cup Brushes (Fig. 13)

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 potential for serious injury.

1.Unplug tool and place it upside down on a level surface as shown. Remove any accessories from spindle.

Wire Cup Brush

WARNING!

Because the wires on wire wheel brushes are directed towards the operator, a guard must be used to protect the operator when fatigued wires break.

2.To install, thread wire cup brush onto spindle. Press the spindle lock button while tightening brush with a 7/8" open end wrench (not provided with tool).

3.To remove wire cup brush, unplug tool and reverse procedure.

Using Wire Wheel Brushes (Fig. 14)

	Guard

Wire wheel brushes are useful for removing rust, scale, burrs, weld slag, etc. A wide variety of wire brushes are available for many applications.

Test wire wheel 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. During this time, no one should stand in front of or in line with it. 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).

WARNING!

Never exceed Maximum Safe Operating Speed of 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.
