Warning
Only use wheels with Maxi-
mum 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.
Before installing any wheel, always inspect it for
cracks. If wheel is cracked, discard it to prevent
others from using it.
Grinding
1. Depending on your job, position the guard to
provide maximum protection for the operator
(Fig. 9).
Selecting Wheels
Grinding is the cutting action of thousands of abra-
sive 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.
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 work-
piece, damage the tool, and cause stress to
wheel that may cause wheel failure.
Warning
To reduce the risk of injury
when grinding:
• ALWAYS hold the tool firmly with both hands
using the handles provided; before and dur-
ing 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
Warning
To reduce the risk of injury
when grinding, ALWAYS use the proper guard.
ALWAYS properly install the guard.
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
finish (Fig. 10). Too great an angle causes too
much pressure on small areas which may gouge
or burn work surface.

Using Type 27 Cut-Off Wheels
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. 11).

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.
3. Control pressure and surface contact between
wheel and workpiece. Too much pressure slows
cutting speed.
Installing and Removing Type 1 Guard Assem-
bly and Adjusting Shoe
1. Unplug tool and place it upside down on a level
surface. Remove any accessories from spindle.
2. Loosen the guard screw and slip the guard over
the spindle.
Position the guard in the location which offers
Warning
A Type 1 guard must be
installed when using a Type 1 cut-off wheel to
provide maximum protection for the operator
if the wheel should break.
