CAUTION: Guards must be used
with all grinding wheels, cutting
wheels, wire brushes and wire
wheels. The DC411 is provided with a
guard intended for use with depressed
center wheels (Type 27) and hubbed
grinding wheels (Type 27). The same
guard is designed for use with and wire
cup brushes.
1. Open the guard latch (p), and align the lugs (m)
on the guard with the slots (n) on the gear case.
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 lugs are aligned
with the slots 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 (o) 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.
CAUTION: If the guard cannot be
tightened by the adjusting clamp, do
not use the tool. To reduce the risk of
personal injury, take the tool and guard
to a service center to repair or replace
the guard.
CAUTION: To reduce the risk of
damage to the tool, 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.
NOTE: Edge grinding and cutting can be performed
with Type 27 wheels designed and specified for this
purpose; 6.35 mm (1/4") thick wheels are designed
for surface grinding while 3.17 mm (1/8") wheels are
designed for edge grinding.
