GENERAL SAFETY RULES
WARNING:
Read all instructions
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1)Work area safety
a)Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b)Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
Power tools create sparks which may ignite
the dust of fumes.
c)Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2)Electrical safety
a)Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b)Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if
your body is earthed or grounded.
c)Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the
risk of electric shock.
d)Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool.
Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e)When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
3)Personal safety
a)Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication.
A moment of inattention while operating
power tools may result in serious personal
injury.
3
English
b)Use safety equipment. Always wear eye
protection.
Safety equipment such as dust mask, nonskid safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
c)Avoid accidental starting. Ensure the switch
is in the off position before plugging in.
Carrying power tools with your finger on the
switch or plugging in power tools that have
the switch on invites accidents.
d)Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.
e)Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool
in unexpected situations.
f)Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
g)If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of these devices can reduce dust-related
hazards.
4)Power tool use and care
a)Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was designed.
b)Do not use the power tool if the switch does
not turn it on and off.
Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c)Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d)Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e)Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tools operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
f)Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g)Use the power tool, accessories and tool bits
etc., in accordance with these instructions
and in the manner intended for the particular
type of power tool, taking into account the
working conditions and the work to be
performed.
Use of the power tool for operations different
from intended could result in a hazardous
situation.
5)Battery tool use and care
a)Ensure the switch is in the off position before
inserting battery pack.
Inserting the battery pack into power tools
that have the switch on invites accidents.
b)Recharge only with the charger specified by
the manufacturer.
A charger that is suitable for one type of
battery pack may create a risk of fire when
used with another battery pack.
c)Use power tools only with specifically
designated battery packs.
Use of any other battery packs may create a
risk of injury and fire.
d)When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small
metal objects that can make a connection
from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
e)Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery
may cause irritation or burns.

(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is just sufficient.
CAUTION:
When the drill bit touches construction iron bar,
the bit will stop immediately and the rotary
hammer will react to revolve. Therefore please grip
the side handle and handle tightly as shown in
Fig. 19.
4.Rotation only
Turn the change lever fully in the direction of the
“ ” mark to set “rotation only”. (Fig. 18)

CAUTION:
䡬
Application of force more than necessary will not
only expedite work at all, but will deteriorate the
tip edge of the drill bit and reduce the service life
of the rotary hammer in addition.
䡬
Drill bit may snap off while withdrawing the rotary
hammer from the drilled hole. For withdrawing,
it is important to use a pushing motion.
䡬
Do not attempt to use the rotary hammer in the
rotation and striking mode with the drill chuck and
chuck adapter attached. This would seriously
shorten the service life of every component of the
machine.
5.When driving wood screws (Fig. 21)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the
driver bit easily slips off the heads of slotted-head
screws.
(2) Tightening wood screws
Prior to tightening wood screws, make pilot holes
suitable for them in the wooden board. Apply the
bit to the screw head grooves and gently drive the
screws in the holes.

8.Switching between the “SAVE“ and the “POWER“
modes
The hammering force of the hammer can be
increased or decreased to conform with intended
usage, by operating the shift knob as per Fig. 25.
Adjust the force to match the usage intended.
“SAVE“ mode
“POWER“ mode
Shift knob
Fig. 25
(1) “SAVE“ mode ... decreased hammering force
This can prevent thin drill bits which are less than
4.3 mm in diameter, from being bent or broken.
(2) “POWER“ mode ... increased hammering force
䡬
This can be used to speedily and efficiently drill
holes when the drill bits which are being used are
greater than 4 mm in diameter.
䡬
This can be used to drill holes into wood or metal.
CAUTION:
Do not drill holes in wood with the “SAVE“ mode.
There is a likelihood that the motor will burn out
because it can easily lock up due to the low power.
MAINTENANCE AND INSPECTION
CAUTION:
1.Inspecting the drill bits
Since use of a dull tool will cause motor
malfunctioning and degraded efficiency, replace
the drill bit with a new one or resharpening without
delay when abrasion is noted.
2.Check the Screws
Loose screws are dangerous. Regularly inspect
them and make sure they are tight.
CAUTION:
Using this power tool with loosened, screws is
extremely dangerous.
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. 17)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn
carbon brush can result in motor trouble, replace
the carbon brush with new ones 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.
Pull out battery before doing any inspection or maintenance.
NOTE:
When replacing the carbon brush with a new one,
be sure to use the Hitachi Carbon Brush Code No.
328481.
5.Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush with a flat head screw driver, etc., as
shown in Fig. 18.
When installing the carbon brush, choose the
direction so that the nail of the carbon brush agrees
with the contact portion outside the brush tube.
Then push it in with a finger as illustrated in Fig.
19. Lastly, install the brush cap.
CAUTION:
●
Be absolutely sure to insert the nail of the carbon
brush into the contact portion outside the brush
tube. (You can insert whichever one of the two
nails provided.)
●
Caution must be exercised since any error in this
operation can result in the deformed nail of the
carbon brush and may cause motor trouble at an
early stage.
