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 posi-
tion. The guard body should be posi-
tioned 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.
NOTE: The guard is pre-adjusted to the diameter of the gear case
hub at the factory. If, after a period of time, the guard becomes
loose, tighten the adjusting screw (M) with clamp lever in the closed
position with guard installed on the tool.
CAUTION: Do not tighten the adjusting screw with the clamp
lever in the open position. Undetectable damage to the guard or the
mounting hub may result.
