WARNING Always remove battery
pack before changing or removing accesso-
ries. Only use accessories specifi cally recom-
mended for this tool. Others may be hazardous.
Installing/Removing Accessories
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.
2. Properly position the guard (Fig. 2).
WARNING Only use accessories with
Maximum 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 mea-
sure of safety. It is not meant to imply a best or
most effi cient operating speed. Do not exceed
the Maximum Safe Operating Speed.
Controlled Start
The controlled start feature reduces the torque
reaction "jerk" when its trigger is pulled.
Paddle Switch Operation
To start the tool, grasp the handle and side handle
fi rmly. 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 lay-
ing the tool down.
General Operation
1. If you have just installed an accessory or are
beginning a period of work, test it by letting it
spin for one minute before applying it to the
workpiece. Out-of-balance or damaged acces-
sories can mar workpiece, damage 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. Hold tool securely with both hands.
4. Start the tool.
5. Allow accessory to come to full speed before
beginning work.
6. Control pressure and surface contact between
accessory and workpiece. Too much pressure
slows speed.
If the tool stalls, release the trigger to reset.
Lighten pressure to avoid stalling.
7. When fi nished, turn off the tool and make sure
it comes to a complete stop before laying it
down.
OPERATION
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
WARNING To reduce the risk of injury,
wear safety goggles or glasses with side shields.
5. Place the selected wheel on the spindle and align
it with the fl ange.
6. Position the fl ange nut over the spindle according
to wheel thickness (Fig. 4).
7. Press in the spindle lock button while turning the
fl ange nut clockwise. Tighten securely using a
spanner wrench.
