Guards

CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire
brushes, and wire wheels. The tool may be used
without a guard only when sanding with conventional
sanding discs. Refer to Figure A to see guards provided
with the unit. Some applications may require purchasing
the correct guard from your local dealer or authorized
servicecentre.
NOTE: Edge grinding and cutting can be performed with Type
27wheels designed and specified for this purpose; 6.35 mm
thick wheels are designed for surface grinding while thinner
Type 27wheels need to be examined for the manufacturer's
label to see if they can be used for surface grinding or only
edge grinding/cutting. A Type 1guard must be used for any
wheel where surface grinding is forbidden. Cutting can also be
performed by using a Type41wheel and a Type 1guard.
NOTE: See the Accessory Chart to select the proper guard /
accessorycombination.

motorhousing.
2. Without separating the gear case from motor housing,
rotate the gear case head to desiredposition.
NOTE: If the gear case and motor housing become separated
by more than 3.17 mm, the tool must be serviced and
re-assembled by a DeWALT service center. Failure to have the
tool serviced may motor and bearingfailure.
3. Reinstall screws to attach the gear case to the motor
housing. Tighten screws to 12.5 in.-lbs. torque.
Overtightening could cause screws tostrip.

WARNING: Use only DeWALT battery packs andchargers.
Kickback Brake™
When a pinch, stall, or bind-up event is sensed, the electronic
brake engages with maximum force to quickly stop the wheel,
reduce the movement of the grinder, and shut the grinder
off. The switch will need to be released then depressed to
restarttool.
Power‑OFF™ Overload Protection
The power supply to the motor will be reduced in case of
motor overload. With continued motor overload, the tool will
shut off. The switch will need to be released then depressed
to restarttool. The tool will power off each time the current
load reaches the overload current value (motor burn-up point).
If continued overload shutdowns occur, apply less force/
weight on the tool until the tool will function without the
overloadengaging.
Soft Start Feature
The soft start feature allows a slow speed build-up to avoid an
initial jerk when starting. This feature is particularly useful when
working in confinedspaces.
Anti‑vibration Side Handle
The anti-vibration side handle offers added comfort by
absorbing the vibrations caused by the tool.
of charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to berecharged.
NOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end-userapplication.
