DeWalt DC410 Instruction Manual page 12

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", the tool must be serviced and re-assembled by a
D WALT service center. Failure to have the tool serviced may
E
cause brush, motor and bearing failure.
3. Re-install screws to attach the gear case to the motor housing.
Tighten screws to 20 in lbs. torque. Overtightening could cause
screws to strip.
Accessories
It is important to choose the correct guards, backing pads and
flanges to use with grinder accessories. See pages 10 and 11 for
information on choosing the correct accessories.
CAUTION: Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels and other acces-
sories running over their rated accessory speed may fly apart and
cause injury. Threaded accessories must have a 5/8"-11 hub. Every
unthreaded accessory must have a 7/8" arbor hole. If it does not, it
may have been designed for a circular saw. Use only the acces-
sories shown on pages 10 and 11 of this manual. Accessory ratings
must always be above tool speed as shown on tool nameplate.
Mounting Guard
MOUNTING AND REMOVING GUARD
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
CAUTION: Guards must be used with all grinding wheels,
sanding flap discs, wire brushes, and wire wheels. The tool may
be used without a guard only when sanding with conventional sand-
ing discs. D WALT model DC410 is provided with a guard intended
E
for use with depressed center wheels (Type 27) and hubbed grind-
ing wheels (Type 27). The same guard is designed for use with
sanding flap discs (Type 27 and 29) and wire cup brushes. Grinding
and cutting with wheels other than Type 27 and 29 require different
accessory guards included with tool. A Type 1 guard is provided for
use with a Type 1 wheel. Mounting instructions for these accessory
guards are included in the accessory package.
1. Open the guard latch (J), and align the
arrow on the guard (K) with the arrow on
the hub (L). This will align the lugs on the
guard with the slots on the gear case
cover.
2. Push the guard down until the guard lugs
engage and rotate freely in the groove on
the gear case hub.
3. With the guard latch open, rotate the
guard (I) into the desired working position.
The guard body should be positioned
between the spindle and the operator to
provide maximum operator protection.
4. Close the guard latch to secure the guard
on the gear case. You should not be able
to rotate the guard by hand when the
latch is closed. Do not operate the grinder
with a loose guard or the clamp lever in
open position.
5. To remove the guard, open the guard
latch, rotate the guard so that the arrows
are aligned and pull up on the guard.
