stop
as
soon
as
the
trigger
switch
is
fully
released.
The
variable

switch
enables
you
to
select
the
best
speed
fora
particular
application.
The
farther
you
squeeze

trigger,
the
faster

without
a
centerpunch,
drilling
in
metals
or
plastics,
driving
screws
and
drilling
ceramics,
or
in
any
application
requiring
high
torque.
Higher
speeds
are
better
for
drilling
in
wood,
wood
compositions
and
for
using
abrasive
and
polishing
accessories.
For
maximum
tool
life,
use
variable
speed
only
for
starting
holes
or
fasteners.
NOTE:
Continuous
use
in
variable
speed
range
is
not
recommended.
It
may
damage
the
switch
and
should
be
avoided.
