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
using 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. 7).
3. Control pressure and surface contact between wheel and work-
piece. Too much pressure slows cutting speed.

To reduce the risk of injury when grinding, ALWAYS use the
proper guard. ALWAYS properly install the guard.
WARNING!
1. Depending on your job, position the guard to provide maximum pro-
tection for the operator (Fig. 5).

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
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. 6). Too great an angle causes
too much pressure on small areas which may gouge or burn work
surface.
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!
5. Control pressure and surface contact between wheel and work-
piece. Too much pressure slows cutting speed.

Using Type 27 Cut-Off Wheels (Fig. 7)
Only use wheels with Maximum Safe Operating Speed rated
at or above the RPM listed on the “WARNING” section of the
tool's nameplate. This speed is based on the strength of the
wheel, allowing for a reasonable measure of safety. It is not
meant to imply a best or most efficient operating speed. Do
not exceed the Maximum Safe Operating Speed.
WARNING!
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.
