Use
the
tip
of
the
pilot
pin
to
determine
the
center
of
the
hole
to
be
drilled.
2
Turn
the
magnet
on
and
verify
that
the
drill
is
in
the
right
position
and
that
the
machine
is
pushed
tight
against
the
work
piece.`

If
your
machine
is
equipped
with
a
auto
coolant
system,
put
open
the
valve
to
release
the
oil.
If
your
machine
does
not
have
a
auto
coolant
system,
fill
the
holes
of
the
spindle
with
oil.
4
Turn
the
motor
on
at
the
highest
setting
and
allow
it
to
run
at
full
speed.
5
Turn
the
arms
to
start
drilling.
Apply
only
a
slight
pressure
when
the
hole
cutter
touch
the
metal.
Do
not
push
the
hole
cutter
with
force
into
the
metal.
6
Apply
a
regular
pressure
while
drilling.
The
drilling
performance
does
not
improve
by
putting
more
pressure
on
the
tool.
Too
much
pressure
will
overload
the
motor
and
your
hole
cutter
will
be
worn
sooner.
Let
the
cutter
do
the
job
and
give
it
time
to
cut
the
metal
!!!

Adjust
the
oil
supply
when
necessary,
if
your
drill
does
not
have
a
auto
coolant
system,
stop
drilling
regularly,
refill
the
holes
of
the
spindle
and
continue
drilling.

Apply
less
pressure
when
the
drill
cuts
through
the
material.

Turn
the
arms
to
put
the
motor
in
highest
position
and
turn
off
the
motor

clean
the
cutter
and
surface
without
getting

a
fully
electronic
motor
unit
which
measures
its
speed
continuously
to
have
the
maximum
power
available.
When
you
start
drilling
the
RPM
can
go
down
for
a
moment
until
the
machine
itself
will
increase
the
RPM.
This
is
completely
normal.
To
