Grinding
WARNING!
A Type “27” guard must be installed when using a grinding wheel to provide maximum protection for the operator if the wheel should break.
Selecting Wheels
Grinding is the cutting action of thousands of abrasive grains on the face of a grinding wheel. When grinding metals such as steel and iron, choose an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel for stone and concrete. Use cotton reinforced wheels for
Type 27 reinforced 1/8"

Operator's Zones
1.Depending on your job, position the guard to provide maximum pro- tection for the operator (Fig. 7).
2.If you have just installed a grinding wheel or are just beginning a period of work, test wheel by letting it spin for one minute before applying it to the workpiece.
NOTE:
3.Firmly grasp body of tool and side handle before starting and while using tool. Allow wheel to come to full speed before starting to grind.
Fig. 8
Hold at a 5° to 15° angle
4.When grinding, hold sander/grinder at a 5o to 15o angle as shown, using constant pressure for a uniform finish. Too great an angle causes concentrated pressure on small areas which may gouge or burn work surface.
5.Control pressure and surface contact between disc and workpiece. Too much pressure slows cutting speed.
