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.
OPERATION
WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
Slide Switch Operation
To start the tool, grasp the handle and side handle
fi rmly and slide the switch to ON.
To stop the tool, release the switch. Make sure
the tool comes to a complete stop before laying
the tool down.
To lock-on the switch, slide the switch to ON and
press down on the front of the switch. To stop the
tool, press and release the switch. Make sure the
tool comes to a complete stop before laying it down.
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 tempera-
ture, 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 a 5 o to 15 o 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 CUT-OFF WHEELS
WARNING
A Type "1" guard must be
installed when using a cut-off wheel to provide
maximum protection for the operator if the
wheel should break.
Type "1" Cut-Off Wheels are suited for small cut-off
and shallow notching operations only.
When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel.
Fig. 6
WARNING
Using the face of a Cut-Off
Wheel (as in grinding) will cause the Wheel
to crack and break, resulting in serious per-
sonal injury.

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.
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
Always install wire cup brushes according to the
accessory manufacterer's instructions.
Fig. 7
Wire Cup Brush
WARNING
Because the wires on wire
wheel brushes are directed towards the op-
erator, a guard must be used to protect the
operator when fatigued wires break.
When using a wire wheel brush, install guard ac-
cording to "Installing/Removing Accessories".
Fig. 8
Guard
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.
Control pressure and surface contact between
wheel and workpiece. Too much pressure causes
over-bending of wires and heat build-up caus-
ing premature wire breaking, rapid dulling and
reduced brush life. Instead of more pressure, try
a wire wheel with more aggressive cutting action
(increased wire size, decreased wire length or dif-
ferent brush type (knot type vs.crimped wire type).
WARNING
Never exceed Maximum
Safe Operating Speed of brush. Do not use
a damaged brush or one that is functioning
improperly (throwing wires, out-of-balance,
etc.). These conditions increase the pos-
sibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
USING SANDING DISCS
Sanding Disc Selection
Use sanding discs 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.
Refer to the table below to select the correct type
of sanding disc for your job. Generally, use 24 or
36 grit for heavy stock removal; 50, 60, or 80 grit
for medium stock removal and 120 grit for fi nishing.
Always begin with a coarse grit, using successively
fi ner grits to obtain the desired fi nish. See your
MILWAUKEE Electric Tool Catalog for a complete
list of sanding discs.
Aluminum Oxide
For fast cutting, general purpose discs for most
metal jobs. Best for cold-rolled steel, stainless
steel or metals requiring tough, fast cutting, long
lasting abrasives.
Aluminum Zirconia Bi-Cut
Unique grit pattern is arranged in clusters for fast-
er stock removal and cleaning. Ideal for removing
paint from cars, boats, etc. without clogging.
Ceramic
Lasts up to 3 times longer than Aluminum Ox-
ide Discs. For general metal working. Ideal for
tough jobs.
Installing Backing Pad and Sanding Discs
1. Unplug the tool.
Wire
2. Wipe the accessories, disc nut and spindle to
Wheel
