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
referstoyourmainsoperated(corded)powertoolorbattery
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and 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.
b) Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
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 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) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach
of children and infirm persons.

similar materials.
䡬By ROTATIONAL action:
Boring holes in metal, wood and plastic.
Tightening wood screws.
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. Fixing the side handle
Attach the side handle to the mounting part.
Rotate the side handle grip in a clockwise direction
to secure it.
Set the side handle to a position that is suited to the
operation and then securely tighten the side handle
grip.

CAUTION
Do not fix the side handle to the ring of the keyless
chuck because of a risk that doing so may damage
the ring.
6. Selecting the appropriate drill bit
䡬When boring concrete or stone:
Use the drill bits for concrete.
䡬When boring metal or plastic:
Use an ordinary metalworking drill bit.
䡬When boring wood:
Use an ordinary woodworking drill bit.
However, when drilling 6.5 mm or smaller holes, use
a metalworking drill bit.
7. Selecting the driver bit
Screw heads or bits will be damaged unless a bit
appropriate for the screw diameter is employed to
drive in the screws.
8. Check the rotational direction (Fig. 3)
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button.
TheL-sideofthepushbuttonispushedtoturnthebit
counterclockwise.
(The

Fig. 3
CAUTION
䡬Never change the direction of bit rotation during
operation.
Turn the power switch OFF before changing the
direction of bit rotation; otherwise, the motor will
burn.
䡬Always use with clockwise rotation, when using it
as an impact drill.
9. IMPACT to ROTATION changeover (Fig. 4)
Theimpactdrillcan beswitchedfromIMPACT(impact
plus rotation) to ROTATION (rotation only) by simply
slidingthechangelever. Whenboringconcrete,stone,
tile or similar board materials, slide the change lever
right. The drill head impacts against the material
while continuing to rotate.
When boring metal, wood or plastic, slide the change
lever fully to the left. The drill simply rotates as an
ordinary electric drill.
Fig. 4
CAUTION
Do not use the impact drill in the IMPACT mode if the
material can be bored by rotation only. Such action
will not only reduce drill efficiency, but may also
damage the drill tip.
When changing over, ensure the change lever is slid
as far as it will go.
HOW TO USE
1. Pressure
Drilling will NOT be accelerated by placing heavy
pressure on the drill. Such action will only result in a
damaged drill bit, decreased drilling efficiency and/
or shortened service life of the drill.
2. Using a large diameter drill bit
Thelargerthedrillbit diameter, the larger thereactive
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, hold the drill
tightly with both hands, and ensure that the drill is
vertical to the material being drilled.
3. When drilling completely through the material
When the drill bit bores completely through the
material, careless handling often results in a broken,
drill bit or damage to the drill body itself due to the
sudden movement of the drill. Always be alert and
ready to release pushing force when drilling through
the material.
4. Switch operation
䡬Whenthetriggerisdepressed,thetoolrotates.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.
Speedislowwhenthetrigger 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.
Turnthespeedcontroldial clockwise forhigherspeed
and counterclockwise for lower speed (Fig. 5).

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.
CAUTION
Drill at a maximum rotation speed when drilling
wooden materials.

(2) Driving in wood screws
䡬Prior to driving in wood screws, make holes suitable
for them on the wooden board. Apply the bit to the
screw head grooves and gently drive the screws into
the holes.
䡬After rotating the screwdriver at low speed for a
while until a wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain
optimum driving force.
CAUTION
䡬Exercise care in preparing a hole suitable for the
wood screws taking the hardness of the wood into
consideration.
Should the hole be excessively small or shallow,
requiring much power to drive the screw into it, the
thread of the wood screw may sometimes be
damaged.
䡬Do not drive machine screws.
MAINTENANCE AND INSPECTION
1. Inspection the drill bit
Continued use of a worn and/or damaged drill bit will

overloadthedrillmotor.Inspectthedrillbitoftenand
replace it with a new bit as necessary.
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.
