WARNINGS
A stuck
bit
can
be
removed
simply
by
setting
the
reversing
switch
to
reverse
rotation
in
order
to
back
out.
However,
the
tool
may
back
out
abruptly
if
you
do
not
hold
it
firmly.
Always
secure
small
workpieces
in
a
vice
or
other
holding
device.
• If
the
tool
is
operated
continuously
until
the
battery
has
discharged,
allow
the
tool
to
rest
for
15
minutes
before
proceeding
with
a
fresh
battery
.
The
exposed
metal
parts
of
the
drill
will
become
very
hot
in
this
type
of
operation.
