To reduce the risk of injury, always
WARNING
use a side handle when using this
tool. Hold securely.

To install, thread side handle into side handle socket
and tighten securely.
To reduce the risk of injury, the
WARNING
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 name-
plate.
• correct accessory, wheel type and grit for the job.
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 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.
Only use accessories with Maxi-
WARNING
mum 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 efficient operating speed. Do not exceed
the Maximum Safe Operating Speed.
Operator's Zones
Installing/Removing Grinding Wheels
Make sure the wheel does not extend beyond the
bottom of the guard. Threaded hub grinding wheels
may require a deeper guard (see "Accessories").
1. Remove the battery pack. WARNING! Always
remove battery pack before changing or removing
accessories.
2. Properly position the guard.
3. Wipe the flange, flange nut and spindle to remove
dust and debris. Inspect the parts for damage. Re-
place if needed. Use only MILWAUKEE mounting
hardware designed for your tool.
4. Place the flange on spindle, as shown.

5. Place the selected wheel on the spindle and align
it with the flange.
6. Position the flange nut over the spindle according
to wheel thickness.
Flange nut
position for
1/8" thick or less wheels
Flange nut
position for
1/4" thick or more wheels
7. Press in the spindle lock button while turning the
flange nut clockwise. Tighten securely.
8. To remove wheel, remove the battery pack and
reverse the procedure.
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 name-
plate.
• correct accessory, wheel type and grit for the job.
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 finishing. Always begin with a coarse grit, us-
ing successively finer grits to obtain the desired finish.
•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 faster stock removal and
cleaning. Ideal for removing paint from cars, boats,
etc. without clogging.
•Ceramic: Lasts up to 3 times longer than Aluminum
Oxide Discs. For general metal working. Ideal for
tough jobs.
