to switch between the different speeds.
MAXIMUM RPM
MODE 1
MODE 2

Controlled Start
The controlled start feature reduces the torque reac-
tion "jerk" when the trigger is pulled.
RAPIDSTOP™
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.
AUTOSTOP™
AUTOSTOP™ detects quick rotations, such as those
caused by kickback, and shuts off the tool.
To test AUTOSTOP™:
1. Remove accessories and their fasteners (such as
nuts or flanges) from the tool.
2. Stand away from objects and people.
3. Firmly grasp the tool's handles.
4. Hold tool away from the body.
5. Start the tool.
6. Quickly rotate the tool about 90° in any direction.
7. If AUTOSTOP™ is working, the tool will shut off
and the AUTOSTOP™ light will flash.
8. If AUTOSTOP™ is not working, the tool will con-
tinue to run. Repeat the test. If the tool will not
automatically shut off, return the tool to the nearest
authorized service center.
Always hold the tool firmly with
WARNING
both hands using the handles
provided before and during grinding.
Paddle Switch Operation
To start the tool, grasp and hold the side handle
triggers, then the main handle firmly. Push the lock-
off button forward and squeeze the paddle switch.
To stop the tool, release the paddle switch or side
handle triggers. Make sure the tool comes to a com-
plete stop before laying down the tool.
General Operation
1. After installing new accessories and befor start-
ing work, test the wheel by letting it spin for
one minute before applying it to the workpiece.
WARNING! Never use an accessory that has
been dropped. Out-of-balance or damaged acces-
sories can mar workpiece, damage the tool, and
cause stress that may cause accessory failure.
MODE 3
MODE 4
6500
8500
2. Use a clamp, vise or other practical means to hold
the workpiece, freeing both hands to control the
tool.
3. WARNING! Hold tool securely with both hands.
Start the tool.
NOTE: If the battery is inserted when the tool is
ON, the tool will not run. Turn the tool OFF, then
back ON to begin work.
4. Allow accessory to come to full speed before
beginning work.
5. Control pressure and surface contact between ac-
cessory and workpiece. WARNING! Never bang
accessory onto work.Too much pressure causes
accessory failure or slows speed.
6. When finished, turn off the tool and make sure it
comes to a complete stop before laying it down.
Using Grinding Wheels
The guard type must match the
WARNING
wheel type to provide maximum
protection for the operator if the wheel should
break.
When grinding, hold tool at a 5° to 15° angle, using
constant pressure for a uniform finish. Too great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.
For best result use only this portion of disc
Using Cut-Off Wheels
Cut-Off Wheels are suited for small cut-off and shal-
low notching operations only.
The guard type must match the
WARNING
wheel type to provide maximum
protection for the operator if the wheel should
break.
When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel. WARNING! Using
the face of a Cut-Off Wheel (as in grinding) will cause
the Wheel to crack and break, resulting in serious
personal injury.
