WARNING
To reduce the risk of injury,
always unplug tool before attaching or removing
accessories or making adjustments. Use only
specifi cally recommended accessories. Others
may be hazardous.
Installing Side Handle
The side handle may be installed on either side of
the gear case. Position the side handle in the loca-
tion which offers best control and guard protection.
To install, thread side handle into side handle socket
and tighten securely.
WARNING
To reduce the risk of injury
when grinding:
•ALWAYS use the proper guard.
•ALWAYS properly install the guard.
•ALWAYS hold the tool fi rmly with both hands
using the handles provided before and during
grinding.
•NEVER use a wheel that has been dropped.
•NEVER bang grinding disc onto work.
•NEVER grind without proper safety
equipment.
Installing, Removing and Adjusting the Guard
This tool is shipped with a guard. The guard must be
used when using the tool as a grinder. The guard may
be removed when using tool as a sander.
1. To
remove
the guard, unplug tool and remove any
accessories from spindle.
2. Loosen the guard bolt.
3. Rotate the guard to align the guard tabs with the
detents on the tool.
4. Pull the guard straight up and away from the
tool.
5. To
install
the guard, unplug the tool and remove
any accessories from the spindle.
6. Loosen the guard bolt and press the guard down
onto the tool. Tighten the guard bolt securely.
7. To
adjust
the guard, loosen the guard bolt and
rotate the guard to the desired position. Tighten
the guard bolt securely.
WARNING
Only use accessories with
Maximum Safe Operating Speed rated at least
equal to the maximum speed marked on the
power tool. 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
effi cient operating speed. Do not exceed the
Maximum Safe Operating Speed.
Installing/Removing Accessories
Make sure the grinding wheel does not extend be-
yond the bottom of the guard. Threaded hub grinding
wheels may require a deeper guard.
1. Unplug the tool.
2. Properly position the
guard.
3. Wipe the fl ange, fl ange
nut and spindle to re-
move dust and debris.
Inspect the parts for
damage. Replace if
needed.
4. Place the fl ange on spindle, as shown.
5. Place the selected wheel on the spindle and align
it with the fl ange.
6. Position the fl ange nut over the spindle according
to wheel thickness.
7. Press in the spindle lock button while turning the
fl ange nut clockwise. Tighten securely using a
spanner wrench.
8. To
remove
wheel, unplug the tool and reverse the
procedure.

General Operation
1. If you have just installed an accessory or are
beginning a period of work, test it by letting it spin
for one minute before applying it to the workpiece.
Out-of-balance or damaged accessories can mar
workpiece, damage the tool, and cause stress that
may cause accessory failure.
2. Use a clamp, vise or other practical means to
hold your work, freeing both hands to control the
tool.
3.Hold tool securely with both hands.
4. Start the tool.
5. Allow accessory to come to full speed before
beginning work.
6. Control pressure and surface contact between
accessory and workpiece. Too much pressure
slows speed.
7. When fi nished, turn off the tool and make sure it
comes to a complete stop before laying it down.
USING GRINDING WHEELS
WARNING
To reduce the risk of injury, the
operator should be instructed in the use, care
and protection of grinding wheels.
Grinding Wheel Selection
Use grinding wheels, and accessories that are:
• correct size as written on tool’s nameplate.
• rated at or above the RPM listed on the tool’s
nameplate.
• correct accessory, wheel type and grit for the job.
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 1 Reinforced 1/8" thick or less Cut-Off Wheels
are suited for small cut-off and shallow notching
operations only. Always handle wheels carefully to
avoid damage. Before installing any wheel, always
inspect it for cracks. If wheel is cracked, discard it
to prevent others from using it.
Care of Grinding & Cut-Off Wheels
Grinding/cut-off wheels should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Grinding and cut-off wheels should be stored:
• in an organized way so wheels can be removed
without disturbing or damaging other wheels
• with their safety information
Grinding and cut-off wheels should NOT be dropped,
rolled or bumped.
Discard wheels that have been dropped, rolled,
bumped, subjected to extreme changes in tem-
perature, or come into contact with solvents or
wetness.
WARNING
To reduce the risk of injury
when grinding, always use the proper guard.
Grinding
When grinding, hold tool at an angle, using constant
pressure for a uniform fi nish. Too great an angle
causes concentrated pressure on small areas which
may gouge or burn work surface.

USING WIRE BRUSHES
WARNING
Everyone in the area must wear
protective clothing and safety goggles or face
shields. Fatigued wires and residue will fl y off the
brush with considerable force, causing potential
for serious injury.
WARNING
Never exceed Maximum Safe
Operating Speed of brush. Do not use a dam-
aged brush or one that is functioning improperly
(throwing wires, out-of-balance, etc.). These con-
ditions increase the possibility of further brush
failure and possible injury. Discard and replace
damaged brushes immediately.
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
WIRE CUP BRUSHES
Always install wire cup brushes according to the
accessory manufacterer’s instructions.

WIRE WHEEL BRUSHES
WARNING
Because the wires on wire
wheel brushes are directed towards the opera-
tor, a guard must be used to protect the operator
when fatigued wires break.
When using a wire wheel brush, install guard accord-
ing to "Installing/Removing Accessories".
Test wheel for balance and loose or damaged wires
by letting it spin for one minute before applying it to
the workpiece. During this time, no one should stand
in front of or in line with it.
