Mounting
the
spring
of
the
tip
arm
‐
When
purchased,
the
spring
of
the
tip
arm
is
not
mounted
on
the
one
side.
As
shown
in
the
figure
on
the
right,
insert
the
spring
shaft
into
the
hole
and
tighten
with
a
lock
nut.
At
this
time,
mounting
is
easier
if
you
lift
the
tip
arm
above
while
working.
‐
There
are
two
mount
holes,
but
only
use
the
mount
hole
on
the
intermediate
bracket
side.
*Caution:
Hang
the
spring
hook
correctly,
(refer
to
the
right
fig.)
*Engage
the
hook
into
the
groove
of
the
plastic
part.
*If
used
for
a
long
time
with
the
spring
mounted
incorrectly,
it
may
significantly
shorten
the
durability
life
of
the
spring.
*Caution:
Tighten
firmly
to
reach
the
nylon
lock
part,
to
prevent
the
nut
from
loosening.
*Caution:
Do
not
place
your
fingers
or
hands
close
to
the
rotating
parts
and
moving
parts.
3)
Setting
the
height
‐
The
working
height
position
is
fixed
using
M6
cap
screws
on
the
collars.
‐
Tighten
the
M6
hex
socket
head
bolts
on
the
collars
firmly.
If
not
tightened
firmly
enough,
the
main
body
may
fall
rapidly,
causing
great
danger.
*Caution:
When
loosening
the
collar
on
the
base
bracket
bottom
side,
support
the
arm
with
one
hand
while
working
so
that
the
arm
does
not
fall
rapidly.
*Caution:
The
recommended
tightening
torque
of
the
M6
hex
socket
head
bolt
is
1.5
N
m.
If
it
is
tightened
too
tightly,
the
brass
part
on
the
tip
of
the
fix
screw
may
deform,
and
may
cause
the
pillar
to
deform.
If
the
pillar
is
deformed,
the
height
of
the
arm
may
become
unadjustable.
