TEMPERATURE
The
ECO.50
‐
T
is
equipped
with
an
all
‐
time
electronic
temperature
protection.
If
the
temperature
of
the
motor
unit
runs
up
to
70
Degree
Celsius
the
motor
unit
will
stop.
After
a
few
minutes
it
can
be
started
again
and
we
recommend
running
the
motor
unloaded
with
the
electronic
speed
adjustment
set
on
100%
in
order
to
let
the
motor
unit
cool
down.
DRILLING
A
HOLE
Now
that
you
have
read
the
explanatory
information
and
safety
recommendations
above,
you
are
ready
to
actually
start
drilling.
Follow
these
10
steps
for
best
drilling
result
:
1
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.
3
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
Annular
Cutter
touch
the
metal.
Do
not
push
the
Annular
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
Annular
Cutter
will
be
worn
sooner.
Let
the
cutter
do
the
job
and
give
it
time
to
cut
the
metal!!!
7
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.
8
Apply
less
pressure
when
the
drill
cuts
through
the
material.
9
Turn
the
arms
to
put
the
motor
in
highest
position
and
turn
off
the
motor
unit.
10
Remove
the
burr,
metal
chips
and
clean
the
cutter
and
surface
without
getting
injuries.
Caution
:
The
metal
piece
drilled
out
can
be
sharp
and
very
hot!!
DRILLING
WITH
ANNULAR
CUTTERS
Annular
cutters
only
cut
material
at
the
periphery
of
the
hole,
rather
than
converting
the
entire
hole
to
shavings.
As
a
result,
the
energy
required
to
make
a
hole
is
lower
than
for
a
twist
drill.
When
drilling
with
an
annular
cutter,
it
is
not
necessary
to
drill
a
pilot
hole.
WARNING:
Do
not
touch
the
cutter
or
the
parts
close
to
the
cutter
immediately
after
operation,
as
they
may
be
extremely
hot
and
cause
burns
to
the
skin.
Ensure
nobody
is
in
the
work
area
where
the
metal
core
is
ejected.
