OPERATION
WARNING
To reduce the risk of injury, always
wear safety goggles or glasses
with side shields. Never grind without proper
safety equipment.
Controlled Start
(some models)
The controlled start feature reduces the torque reac
-
tion "jerk" when its trigger is pulled.
Constant Speed Tachometer
(some models)
The constant speed tachometer keeps the tool's
revolutions per minute at an almost constant speed
even under load. The tachometer also helps pre
-
vent tool overheating. 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.
Electric Brake
(some models)
The electric brake engages when the trigger is re
-
leased, causing the wheel to stop and allowing you
to proceed with your work. Generally, the wheel stops
within six seconds. However, there may be a delay
between the time you release the trigger and when
the brake engages. Occasionally the brake may miss
completely. If the brake misses frequently, the saw
needs servicing by an authorized MILWAUKEE ser
-
vice facility.
Make sure the tool comes to a complete
stop before laying it down.
WARNING
Always hold the tool firmly with
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.
To
lock-on
the switch, start the tool and push in the
lock-on button. To stop the tool, squeeze and 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:
On some models, 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.
Using Grinding Wheels
WARNING
The guard type must match the
wheel type to provide maximum
protection for the operator if the wheel should
break.
When grinding, hold tool at a 5
o
to 15
o
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
Hold at a 5° to
15° angle
