PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, inviting serious accident.
3. Extension cord
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 metal or plastic
Use ordinary metalworking drill bits.
䡬 When boring wood
Use ordinary woodworking drill bits.
However, when drilling 6.5 mm or smaller holes, use
a metalworking drill bit.
5. Mounting and dismounting of the bit (Fig. 1)
(1) Open the chuck jaws, and insert the bit into the chuck.

8. Install the stopper (Fig. 4)
(1) Loosen the side handle and insert the straight portion
of the stopper into the handle bolt hole.
(2) Move the stopper to the specified position and rotate
the grip of the side handle clockwise to fix the stopper.
9. Installing the hook (optional accessory) (Fig. 5)
(1) Insert the hook into the hole of Section A on the main
body and turn it clockwise.
When the nut reaches the washer surface of the handle
cover, tighten it with a wrench.
(2) It is also possible to install the hook on the opposite
side. To do so, follow the same procedures mentioned
above.
(3) It is possible to hang the hook on a waist belt or a
pipe up to maximum 28 mm in diameter, and so on.
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.
HOW TO USE
1. Switch operation
䡬 When the trigger is depressed, the tool rotates.
When the trigger is released, the tool stops.
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. Drilling
䡬 Always apply pressure in a straight line with the bit.
Use enough pressure to keep drilling, but do not push
hard enough to stall the motor or deflect the bit.
䡬 To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last part of the hole.
䡬 If the drill stalls, release the trigger immediately,
remove the bit from the work and start again. Do not
click the trigger on and off in an attempt to start a
stalled drill. This can damage the drill.
䡬 The larger the drill bit diameter, the larger the reactive
force on your arm.
Be careful not to lose control of the drill because of
this reactive force.
To maintain firm control, establish a good foothold,
use side handle, hold the drill tightly with both hands,
and ensure that the drill is vertical to the material being
drilled.
(2) Insert the brush holder together with carbon brushes
into the brush holder chamber in the housing.
(3) Carefully ascertain that the internal wiring and so on
are located at their regular positions, and that there
is no possibility of the rotray part (armature) being
contacted by the internal wiring or other items.
(4) Reinstall the handle cover while exercising adequate
care not to allow the internal wiring and so on to
become caught in the housing, then tighten the handle
cover with four machine screws.
CAUTIONS
䡬 When reassembling after replacing the carbon
brushes, be sure to follow this assembling procedure.
䡬 When replacing the carbon brushes, do not tamper
with parts other than those necessary for replacing.
NOTE
Due to HITACHI’s continuing program of research and
development, the specifications herein are subject to
change without prior notice.
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 (Fig.6)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace a carbon
brush with a new one which has the same brush No.
shown in the figure when it becomes worn to or near
the ‘wear limit’. In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
