WARNING
wear proper eye protection marked
to comply with ANSI Z87.1. Never grind without
proper safety equipment.
To reduce the risk of injury, wear a dust mask or
use an OSHA compliant dust extraction solution
when working in dusty situations.
Thermal Overload Protection
The tool switches itself off automatically when the
motor is overloaded. If this happens, release the
trigger to reset. Pull the trigger and continue work.
Mechanical Brake
The mechanical brake engages when the trigger is
released, causing the wheel to stop and allowing you
to proceed with your work. Generally, the wheel stops
within two seconds. If it takes longer than two sec-
onds, ensure that you have the correct accessories
installed and try again. If the problem still occurs, the
tool needs servicing by an authorized MILWAUKEE
service facility. Make sure the tool comes to a com-
plete stop before laying it down.
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 the handle and side handle
firmly. Pull the lock-off button back and squeeze the
paddle switch.
To stop the tool, release the paddle switch. Make
sure the tool comes to a complete stop before laying
the tool down.
General Operation
1. If you have just installed an accessory or are
beginning a period of work, test the wheel by
letting it spin for one minute before applying it to
the workpiece. WARNING! Never use a grinding
wheel that has been dropped. Out-of-balance or
damaged accessories can mar workpiece, dam-
age 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. WARNING! Hold tool securely with both hands.
Start the tool.
NOTE: If the tool is plugged in when the tool switch
is in the "ON" position, 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
accessory and workpiece. WARNING! Never
bang grinding wheel 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.
