When the work area is removed from the power
source. Use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Selecting the appropriate drill bit
䡬 When boring concrete or stone
Use the drill bits specified in the Optional Accessories.
䡬 When boring metal or plastic
Use an ordinary metalworking drill bit.

To attach the hook (A), it is necessary to disassemble
the handle portion which covered the tool’s electrical
system. For your continued safety and electrical shock
protection, installing the hook (A) on this drill should
ONLY be performed by a HITACHI AUTHORIZED
SERVICE CENTER.
CAUTION:
When the power tool is used with a hook fixed to it,
pay attention to the following points:
䡬 Before hanging the main unit from the waist belt,
make sure that the drill has come to a complete stop.
While it is suspended from the waist belt, the power
plug must be disconnected from the power source.
䡬 Do not walk about with the power tool hanging from
the waist belt.
䡬 In the case of operation in a high place, it is dangerous
to drop the tool accidentally. If the hook is deformed
or hung from the wrong position, there is danger that
the hook will slip off and the tool will fall.
Be careful to avoid danger.
䡬 In making a through hole, the power tool sometimes
shakes violently when the workpiece is pierced, from
example. Be careful you are not hurt by the hook
even if such situation happens.

the material can be bored by rotation only. Such
action will not only reduce drill afficiency, but
may also damage the drill tip.
mid-position may result in damage. When
switching, make sure that you shift the change
lever to the correct position.
HOW TO USE
1. Switch operation
䡬 When the trigger is depressed, the tool rotates. When
the trigger is released, the tool stops.
䡬 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.
䡬 The desired rotation speed can be pre-selected with
the speed control dial.
Turn the speed control dial clockwise for higher speed
and counterclockwise for lower speed. (Fig. 7)
䡬 Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
2. When using as a Drill or an Impact Drill
(1) Pressing force of the drill
You cannot drill holes more quickly even if you press
the drill with a stronger force than necessary. It not
only damages tip of drill bit and decreases the
efficiency of operation, but also shortens the life of
the drill tip.
(2) In case of penetrating holes
Drill bits can be broken when the material being
drilled is penetrated. It is important to decrease
pressing force just before penetrating.
CAUTION:
In continuous operation, conduct no-load operation
for five seconds after completing a drilling job.
(3) When a thick drill bit is used
Your arm is subjected to larger reaction force when a
thicker drill bit is used. Be careful not to be moved by
the reaction force. For this, establish a foothold, hold
the unit tightly with both hands perpendicularly to
the material being drilled.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded efficiency, replace the
drill bits with a new one or resharpening without
delay when 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. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.
