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 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-O Wheels
are suited for small cut-o 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-O Wheels
Grinding/cut-o wheels should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Grinding and cut-o 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-o 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
Only use accessories with Maxi-
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 ecient operating speed. Do not exceed
the Maximum Safe Operating Speed.
Installing/Removing Grinding Wheels
Make sure the wheel does not extend beyond the
bottom of the guard.
1. Remove the battery pack. WARNING! Always
remove battery pack before changing or removing
accessories.
2. Properly position the guard.
3. Wipe the ange, spindle and ange nut 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 selected wheel on the spindle and align
it with the ange.
5. Position the ange nut over the spindle according
to wheel thickness.

1/4" thick or more wheels
6. Press in the spindle lock button while turning the
ange nut clockwise. Tighten securely.
7. To remove wheel, remove the battery pack and
reverse the procedure.
Installing/Removing/Cleaning
the Dust Screen
Using the dust screen will increase the performance
and extend the life of the tool.
1. To attach the dust screen, snap the screen over
the tool’s handle.
2. To remove the dust screen, insert a at screw-
driver into the notch at the top of the dust screen
and pry away from the tool.
3. To clean the dust screen, tap against a hard sur-
face, or blow clean with compressed air.
OPERATION
WARNING
To reduce the risk of injury, always
wear proper eye protection marked
to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Never grind without proper safety equipment.
Controlled Start
The controlled start feature reduces the torque reac-
tion "jerk" when the trigger is pulled.
Electric Brake
The electric brake engages when the switch is re-
leased, causing the wheel to stop within seconds.
There may be a delay between the time the switch is
released and when the brake engages. Occasionally
the brake may miss completely. If the brake misses
frequently, have the tool serviced by an authorized
MILWAUKEE service facility. Make sure the tool
comes to a complete stop before laying it down.
