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 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 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 tighten the sleeve by turning it toward the right (in
the clockwise direction as viewed from the front) (See
Fig.
8
).
○
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
Loosen the sleeve by turning it toward the left (in the
counter-clockwise direction as viewed from the front)
(See
Fig.
8
).
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.
9
) (The
L
and
R
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.
○
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 driver drill within 10-15 kg pressing force
while drilling into brick.
12.
Using
the
light
Pull the trigger switch to light up the light. The light keeps
on lighting while the trigger switch is being pulled. The
light goes out after releasing the trigger switch. (
Fig.
10
)
(The light automatically goes out 10 seconds after
releasing the trigger switch.)
CAUTION
Do not expose directly your eye to the light by looking into
the light.
If your eye is continuously exposed to the light, your eye
will be hurt.
13.
Using
the
hook
(sold
separately)
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) Placing 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.(
Fig.
11
)
(2) Removing the hook.
Remove the screws
fi
xing the hook with Philips screw
driver. (
Fig.
12
)
CAUTION
Only Hitachi STANDARD ACCESSORIES phillips bit
(No. 2 × 65L; Code No. 983006) 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.
3.
Maintenance
of
the
motor
The motor unit winding is the very “heart” of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4.
Cleaning
on
the
outside
When the driver drill is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
5.
Storage
Store the driver drill in a place in which the temperature is
less than 40°C and out of reach of children.
NOTE
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.
NOTE
Storing Lithium-ion Batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge may
result in performance deterioration, signi
fi
cantly reducing
battery usage time or rendering the batteries incapable of
holding a charge.
