Metal
For
drilling
with
a
metal
working
drill
bit.
○
The
rotational
speed
of
the
drill
can
be
controlled
by
varying
the
amount
that
the
trigger
switch
is
pulled.
Speed
is
low
when
the
trigger
switch
is
pulled
slightly
and
increases
as
the
trigger
switch
is
pulled
more.
NOTE
A
buzzing
noise
is
produced
when
the
motor
is
about
to
rotate;
This
is
only
a
noise,
not
a
machine
failure.
11.
For
drilling
into
brick
Excessive
pressing
force
never
increases
drilling
speed.
It
will
not
only
damage
the
drill
tip
or
reduce
working
e
ffi
ciency,
but
could
also
shorten
the
service
life
of
drill
bit.
Operate
the
impact
driver
drill
within
10-15
kg
pressing
force
while
drilling
into
brick.
12.
Using
the
hook
The
hook
is
used
to
hang
up
the
power
tool
to
your
waist
belt
while
working.
CAUTION
○
When
using
the
hook,
hang
up
the
power
tool
fi
rmly
not
to
drop
accidentally.
If
the
power
tool
is
dropped,
it
may
lead
to
an
accident.
○
When
carrying
the
power
tool
with
hooked
to
your
waist
belt,
do
not
fi
t
any
bit
to
the
tip
of
power
tool.
If
the
sharp
bit
such
as
drill
is
fi
tted
to
the
power
tool
when
carrying
it
with
hooked
to
your
waist
belt,
you
will
be
injured.
○
Install
securely
the
hook.
Unless
the
hook
is
securely
installed,
it
may
cause
an
injury
while
using.
(1)
Removing
the
hook.
Remove
the
screws
fi
the
hook
with
screw
driver.
(
Fig.
11
)
(2)
Replacing
the
hook
and
tightening
the
screws.
Install
securely
the
hook
in
the
groove
of
power
tool
and
tighten
the
screws
to
fi
x
the
hook
fi
rmly.

may
be
used.
Do
not
use
other
bits
since
they
may
come
loose.
MAINTENANCE
AND
INSPECTION
1.
Inspecting
the
tool
Since
use
of
as
dull
tool
will
degrade
e
ffi
ciency
and
cause
possible
motor
malfunction,
sharpen
or
replace
the
tool
as
soon
as
abrasion
is
noted.
2.
Inspecting
the
mounting
screws
Regularly
inspect
all
mounting
screws
and
ensure
that
they
are
properly
tightened.
Should
any
of
the
screws
be
loose,
retighten
them
immediately.
Failure
to
do
so
could
result
in
serious
hazard.
CAUTION
○
The
selection
examples
shown
in
Table
5
should
be
considered
as
general
standard.
As
di
ff
erent
types
of
tightening
screws
and
di
ff
erent
materials
to
be
tightened
are
used
in
actual
works
proper
adjustments
are
naturally
necessary.
○
When
using
the
impact
driver
drill
with
a
machine
screw
at
HIGH
(high
speed),
a
screw
may
damage
or
a
bit
may
loose
due
to
the
tightning
torque
is
too
strong.
Use
the
impact
driver
drill
at
LOW
(low
speed)
when
using
a
machine
screw.
NOTE
The
use
of
the
battery
in
a
cold
condition
(below
0
degree
Centigrade)
can
sometimes
result
in
the
weakened
tightening
torque
and
reduced
amount
of
work.
This,
however,
is
a
temporary
phenomenon,
and
returns
to
normal
when
the
battery
warms
up.
7.
Mounting
and
dismounting
of
the
bit
(1)
After
inserting
a
driver
bit,
etc.
into
the
keyless
drill
chuck,
fi
rmly
grasp
the
ring
and
tighten
the
sleeve
by
turning
it
toward
the
right
(in
the
clockwise
direction
as
viewed
from
the
front)
(See
Fig.
9
).
○
If
the
sleeve
becomes
loose
during
operation,
tighten
it
further.
The
tightening
force
becomes
stronger
when
the
sleeve
is
tightened
additionally.
(2)
Dismounting
the
bit
Firmly
grasp
the
ring
and
loosen
the
sleeve
by
turning
it
toward
the
left
(in
the
counter-clockwise
direction
as
viewed
from
the
front)
(See
Fig.
10
).
CAUTION
When
it
is
no
longer
possible
to
loosen
the
sleeve,
use
a
vise
or
similar
instrument
to
secure
the
bit.
Set
the
clutch
mode
between
1
and
11
and
then
turn
the
sleeve
to
the
loose
side
(left
side)
while
operating
the
clutch.
It
should
be
easy
now
to
loosen
the
sleeve.
8.
Con
fi
rm
that
the
battery
is
mounted
correctly
9.
Check
the
rotational
direction
The
bit
rotates
clockwise
(viewed
from
the
rear
side)
by
pushing
the
R-side
of
the
selector
button.
The
L-side
of
the
selector
button
is
pushed
to
turn
the
bit
counterclockwise
(See
Fig.
10
)
(The
and
marks
are
provided
on
the
body).
CAUTION
Always
use
this
unit
with
clockwise
rotation,
when
using
it
as
an
impact
drill.
10.
Switch
operation
○
When
the
trigger
switch
is
depressed,
the
tool
rotates.
When
the
trigger
is
released,
the
tool
stops.
