Operation
Guidelines
Read
the
next
sections
carefully.
They will
help
you
use
your
MolD-TOOl
correctly
and
help
you
select
the
correct
accessory
for
your
job.
Using
the Moto-Tool
The
first
step
in learning
to use the Moto-Tool
is to get
the
"feel"
of it.
Hold
it in your
hand
and
feel
its
weight
and
balance.
Feel
the
taper
of the
housing.
This
taper
permits
the
Moto-Tool
to be
grasped
much
like
a pen or
pencil.
If you
nave
a variable
speed
model,
turn
iron
by sliding
the switch
speed
indicator
to each
of the speed
settings
(1 Ihru 5), allowing
the
toot
to
maintain
full
speed
at
each
setting.
If you
have
a two-speed
model,
turn
it on by sliding
the switch
indicator
to the LOW
speed
setting.
You
will notice
a detent
at this
setting.
Then
slide
the switch
indicatortothe
HIGH
speed
setting.
You
will
also
notice
a
detent
at this
setting.
If you
have
a single
speed
model,
turn
it on by sliding
the switch
indicator
to
the
on
position,
you
will
also
notice
a detent
at this
setting.
When
you
turn
on
the
tool
for the
first
time,
hold
it away
from
your
face.
Accessories
can
be
damaged
during
handling,
and
can
fly
apart
as they
come
up to speed.
This is not
common,
but
it does
happen.
Practice
on scrap
materials
first
to see how
the
Moto-Tool
cuts.
Keep
in mind
that
the
work']s
done
by the
speed
of the tool
and by
the
accessory
in the
chuck.
You
should
not
lean
on or push
the tool
into
the work.
Instead,
lower
the
spinning
accessory
lightly
to the work
and
allow
it to touch
the point
at.
which
you
want
cutting
(or
sanding
or etch-"
ing,
etc.)
to begin.
Concentrate'on
guiding
the
tool
over
the
work
using
very
little
pros-
sure from
your
hand.
Allow
the accessory
to
do the work.
Usually,
it is best
to make
a series
of passes
with the tool
rather
than
attempt
to do all the
work
in one pass.
To make
a cut.
for example,
pass
the tool
bacX
and
forth
over
the
work,
much
as
you
would
a
small
paint
brush.
Cut
a little
material
on
each
pass
until
you
reach
the desired
depth.
For
most
work,
the
deft,
gentle
touch
is best.
With
it, you
have
me
best
control,
are
less
likely
to
make
errors,
and will get the
most
efficient
work
out
of the accessory.
The
pencil
grip
we described
is one
way
to
hold the Moto-Tool.
A second
way to grip the
tool
much
as you
would
the
handgrip
on a
bicycle,
with
your
hand
wrapped
around
the
housing
and the chuck
extending
just
beyond
your
thumb
and forefinger.
This
grip
must
be
used for cutoff
wheels
and
saws
for maximum
control
and
is
often
used
with
polishing,
brushing,
and
grinding
accessories.
When
using
the
steel
saws
(No.s.
400,
406)
or
cutoff
wheels
(Nos.
409,
420,
426)
always
have
the
work
securely
clamped.
Never
attempt
to
hold
the work
with
one
hand
while
using
either
of these
accessories.
The
reason
is
that
these
wheels
will
grab
if they
become
slightly
canted
in the
groove,
and
can
kick-
back
causing
loss
of
control
resulting
in
serious
injury.
Your
second
hand
should
be
used
to steady
and
guide
the
hand
holding
the
tool.
When
a
cutoff
wheel
grabs,
the
wheel
itself
usually
breaks.
When
the steel
saw
wheel
grabs,
it
may
jump
from
the
groove
and
you
could
lose
control
of the
tool.
f,'
For best control
in close work,
grip the Moto-
Tool
like a pencil
between
your
thumb
and
forefinger.
This is the "handgrip" method of holding the
tool used for operations such as grinding
a
flat surface.
The operation
of any power
tool can result
in foreign
objects
being thrown
into the eyes. ,which can
result in severe eye damage.
Always
wear
safety
glasses or eye shields before commencing
oo,,ver tool
operation.
We
recommended
Wide
Vlsion
Safety
Mask
for use over
spectac!es
or standard
safety glasses.
Whenever
you hold
the tool, be careful
not to
cover
the
air
vents
with
your
hand.
This
blocks
the air
flow
and
causes
the motor
to
overheat.

COLLET
-- Consists
of a collet

To loosen,
first
slide
shaft
lock
forward
and
rotate
the shaft
by hand
until the lock
engages
the
shaft
preventing
further
rotation.
(NOTE:
Do not engage
lock
while
the Moto-
Tool
is running.)
With
the lock engaged
use
the
collet

to loosen
the
collet
nut.
Change

inserting
the
new

Into
the
collet
as far
as possible
to minimize

and unbalance.
With
the lock
engaged,
tighten
the collet
nut with the wrench
until the
accessory
shank
is gripped
by
the
poller.
Avoid
excessive
tightening
of Ihe

This

is best
when
using
the same

periods
or during

sizes,
are
available
for your
Moto-Tool.
To
install
a different
toilet,
remove
the cotlet
nut
and remove
the old collet.
Insert
the unslotted
end of the cotlet
in the
hole
in the
end
of the
tool
shaft.
Replace
collet
nut
on
the
shaft.
Always
use
the
collet
which
matches
the
shank
size
of the accessory
you
plan
to use.
Never
force
a larger
diameter
shank
into
a
collet.
KEYLESS
CHUCK--Can
be threaded
on the
end
of the
shaft
by
engaging
the
shaft
lock
button,
you
need
only
use
hand
tightening
to
secure
an accessory.
Use
the keyless
chuck
when
there
is a need
to change
bits frequently,
for light
duty
jobs.
BALANCING
ACCESSORIES
-- For precision
work,
it is important
that all accessories
be in
good
balance
(much
the same
as the tires
on
your
automobile).
To true
up or balance
an
accessory,
slightly
loosen
collet
nut and
give
the accessory
or collet
a I/4"
turn.
Retighten
toilet
nut and run the Moto-Toot.
You should
be able to tell by the sound
and
feel
if your
accessory
is running
in
balance.
Continue
adjusting
in this fashion
until
best
balance
is
achieved.
To maintain
balance
on
abrasive
wheel
points,
before
each use, with
the wheel
point secured
in me toilet,
turn
on the Moto-
Tool
and run
the 415 Dressing
Stone
lightly
against
the
revolving
wheel
point.
This
removes
high
soots and trues
up
the
wheel
point for good
balance.
WHEEL
DIAMETER
-- Other
than
the No. 426
cutoff wheel, do not use grinding
wheels
over
1" in diameter,
Mote-Tool's
high
speed
can
cause
larger
wheels
to fly apart
and
could
cause injury.
SAFETY
-- Protect
your
ey_es when
grinding
or routing
with the Moto-Tool...
always
wear
an approved
type of safety
glasses.
Remember.
your
new Dremel
Moto-Tool
is
the
finest
power
tool
of
its
kind.
But
its
performance
is
only
as
good
as
the
accessories
with
wmct_
it
is
used.
"_'e
recommend
onb/ Oreme{
accessories
to be
used,"
"Use of any
other
accessories
may
create
a hazard."
We hope
you'll
enjoy
many
years
of trouble
free
pleasure
from
your
Oremel
Moto-Tool.
