Using Type 27 Cut-Off Wheels (Fig. 11)
Type 27 cut-off wheels are only suited for small cut-off and shallow notching
operations.
1. Firmly grasp rear handle and side handle before starting and while us-
ing tool. Allow wheel to come to full speed before starting.
2. When using a cut-off wheel, hold tool as shown, using only the edge of
the wheel (Fig. 11).
3. Control pressure and surface contact between wheel and workpiece.
Too much pressure slows cutting speed.

Grinding (Fig. 9 & 10)
1. Depending on your job, position the guard to provide maximum protec-
tion for the operator (Fig. 9).

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 shal-
low notching operations only.
2. If you have just installed a grinding wheel or are just beginning a
period of work, test the 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 rear handle and side handle before starting and while
using tool. Allow wheel to come to full speed before starting to grind.
4. When grinding, hold tool at a 5
o
to 15
o
angle as shown, using con-
stant pressure for a uniform finish (Fig. 10). Too great an angle causes
too much pressure on small areas which may gouge or burn work
surface.

Hold at a 5° to 15° angle
5. Control pressure and surface contact between wheel and workpiece.
Too much pressure slows cutting speed.
WARNING!
A Type 27 guard must be installed when using a Type 27 cut-
off wheel to provide maximum protection for
the operator if the wheel should break.
WARNING!
To reduce the risk of injury when grinding, ALWAYS use the
proper guard. ALWAYS properly install the guard.
WARNING!
To reduce the risk of injury when grinding:
ALWAYS hold the tool firmly with both hands using the
handles provided; before and during grinding
NEVER allow the wheel to bind
NEVER use a wheel that has been dropped
NEVER bang grinding wheel onto work
NEVER grind without proper safety equipment
