Type 27 cut-off wheels are only suited for small cut-off and shallow notch-
ing 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 workpiece.
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 protec-
tion for the operator (Fig. 5).

WARNING
To reduce the risk of injury when grinding:
• ALWAYS hold the tool fi rmly 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 constant
pressure for a uniform fi nish (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 workpiece.
Too much pressure slows cutting speed.

Using Type 27 Cut-Off Wheels
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, allow-
ing for a reasonable measure of safety. It is not meant to imply a
best or most effi cient 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 shal-
low notching operations only.
