How
to
make
the
batteries
perform
longer.
(1)
Recharge
the
batteries
before
they
become
completely
exhausted.
When
you
feel
that
the
power
of
the
tool
becomes
weaker,
stop
using
the
tool
and
recharge
its
battery.
If
you
continue
to
use
the
tool
and
exhaust
the
electric
current,
the
battery
may
be
damaged
and
its
life
will
become
shorter.
(2)
Avoid
recharging
at
high
temperatures.
A
rechargeable
battery
will
be
hot
immediately
after
use.
If
such
a
battery
is
recharged
immediately
after
use,
its
internal
chemical
substance
will
deteriorate,
and
the
battery
life
will
be
shortened.
Leave
the
battery
and
recharge
it
after
it
has
cooled
for
a
while.
PRIOR
TO
OPERATION
1.
Setting

).
2.
Tightening
torque
adjustment
(1)
Tightening
torque
Tightening
torque
should
correspond
in
its
intensity
to
the
screw
diameter.
When
too
strong
torque
is
used,
the
screw
head
may
be
broken
or
be
injured.
Be
sure
to
adjust
the
clutch
dial
position
according
to
the
screw
diameter.
(2)
Tightening
torque
indication
The
tightening
torque
di
ff
ers
depending
on
the
type
of
screw
and
the
material
being
tightened.
The
unit
indicates
the
tightening
torque
with
the
numbers
“1,
3,
5
...
22”
on
the
clutch
dial,
and
dots.
The
tightening
toque
at
position
“1”
is
the
weakest
and
the
torque
is
strongest
at
the
highest
number
(See
Fig.
5)
.
(3)
Adjusting
the
tightening
torque
Rotate
the
clutch
dial
and
line
up
the
numbers
“1,

rotation
may
be
locked
to
cease
while
the
unit
is
used
as
drill.
While
operating
the
combi
drill,
take
care
not
to
lock
the
motor.
○
Too
long
hammering
may
cause
the
screw
broken
due
to
excessive
tightening.
3.
Rotation
to
Impact
changeover
(See
Fig.
5)
The
“Rotation
(Rotation
only)”
and
“Impact
(Impact
+
Rotation)”
can
be
switched
by
aligning
the
drill
mark
“
”
or

CAUTION
○
If
an
operation
which
is
normally
performed
at
the
“Rotation”
setting
is
performed
at
“Impact”
setting,
the
e
ff
ect
of
making
holes
does
not
only
increase
but
it
may
also
damage
the
bit
or
other
