Grinding
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 non-ferrous
metals.
Type 27 reinforced 1/8" cut-off wheels are suited for small cut-off and
shallow notching operations only.

1.
When guard is properly positioned, place flange on spindle with
flange facing away from tool.

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: Out-of-balance wheels can mar workpiece, damage the tool,
and cause stress to wheel that may cause wheel failure.
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.

4.
When grinding, hold sander/grinder at a 5
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.
WARNING!
Hold at a 5° to 15° angle
