2. Tightening torque adjustment
(1)
Tightening
torque
Tightening
torque
should
correspond
in
its
intensity
to
the
screw
diameter.
When
too
strong
torque
is

may
be
broken
or
be
injured.
Be
sure
to
adjust
the
clutch
dial
position
according
to
the
screw
diameter.
(2)
Tightening
torque

Changing
the
speed
while
the
motor
is
rotating
will

○
When
setting
the
shift
knob
to
“HIGH”
(high
speed)
and
the
