ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
causeinjury.
Attaching Side Handle (Fig. B)

WARNING: Before using the tool, check that the handle is
tightenedsecurely.
Screw the side handle
4
tightly into one of the holes on
either side of the gear case. The side handle should always
be used to maintain control of the tool at alltimes.
Rotating the Gear Case (Fig. C)
To improve user comfort, the gear case will rotate 90° for
cuttingoperations.
1. Remove the four corner screws attaching the gear case
to 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 1/8" (3.17 mm), the tool must be
serviced and reassembled by a DeWALT service center.
Failure to have the tool serviced may lead to 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.
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
the Accessories Chart to see guards provided with the unit.
Some applications may require purchasing the correct guard
from your local dealer or authorized servicecenter.
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: Refer to the Accessories Chart to select the proper
guard/accessorycombination.
Adjusting and Mounting Guard(Fig.D)

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack before
making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
causeinjury.
One-touch
TM
: The engaging face is slanted and will ride
over to the next alignment hole when the guard is rotated
in a clockwise direction (spindle facing user) but self-locks in
the counterclockwisedirection.
Mounting Guard

CAUTION: Prior to mounting guard, ensure the screw,
lever, and spring are fitted correctly.
1. With the spindle facing the operator, press and hold the
guard release lever
8
.
2. Align the lugs
11
on the guard with the slots
12
on the
gearcasecover.
3. Push the guard down until the guard lugs engage and
rotate them in the groove on the gear case cover. Release
the guard releaselever.
4. To position the guard, rotate the guard clockwise
into the desired working position. Press and hold the
guard release lever
8
to rotate the guard in the counter-
clockwisedirection.
NOTE: The guard body should be positioned between
the spindle and the operator to provide maximum
operatorprotection.
The guard release lever should snap into one of the
alignment holes
13
on the guard collar. This ensures that
the guard issecure.
5. To remove the guard, follow steps 1–3 of these
instructions inreverse.
Flanges and Wheels

CAUTION: Turn unit off and unplug the tool before
making any adjustments or removing or installing
attachments oraccessories.
Mounting Non-Hubbed Wheels (Fig.E)

WARNING: Failure to properly seat the flanges and/or
wheel could result in serious injury (or damage to the tool
orwheel).

CAUTION: Included flanges must be used with depressed
center Type 27/42 grinding wheels and Type1/41 cutting
wheels. Refer to the Accessories Chart for moreinformation.

WARNING: A closed, two-sided cutting wheel guard is
required when using abrasive cutting wheels or diamond
coated cuttingwheels.

WARNING: Use of a damaged flange or guard or fail ure
to use proper flange and guard can re sult in injury due to
wheel breakage and wheel contact. Refer to the Accessories
Chart for moreinformation.
1. Place the tool on a table, guardup.
2. Install the backing flange
5
on spindle
3
with the raised
center (pilot) facing thewheel. Press the backing flange
intoplace.
3. Place wheel
16
against the backing flange, centering
the wheel on the raised center (pilot) of the backingflange.
4. While depressing the spindle lock button and with the
hex depressions facing away from the wheel, thread the
locking flange
6
on spindle so that the lugs engage the
two slots in thespindle.
5. While depressing the spindle lock button, tighten the
locking flange
6
by hand or using the wrench supplied.
(Only use a locking flange if it is in perfect condition.) Refer
to the Accessories Chart to see flangedetails.
6. To remove the wheel, reverse the aboveprocedure.
Mounting Sanding Backing Pads (Fig.A, F)
NOTE: Use of a guard with sanding discs that use backing
pads, often called fiber resin discs, is not required. Since a
guard is not required for these accessories, the guard may or
may not fit correctly ifused.

WARNING: Failure to properly seat the clamp nut and/
or pad could result in serious injury (or damage to the tool
orwheel).
