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
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.

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. Grounding
This tool should be grounded while in use to protect
the operator from electric shock. The tool is equipped
with a three conductor cord and grounding type
plug to fit the proper grounding type receptacle. The
green (or green and yellow) conductor in the cord
is the grounding wire. Never connect the green (or
green and yellow) wire to a live terminal.
3. 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.
4. 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.
CAUTION
Damaged cord must be replaced or repaired.
5. Confirming condition of the environment
Confirm that the work site is placed under
appropriate conditions conforming to prescribed
precautions.
6. How to select drill bits
(1) When drilling holes in metals or plastics
Use ordinary metalworking drill bits,
applicable drill sizes range from min. 1.2 mm
to max. 13 mm.
3
(2) When drilling holes in lumber
Use woodworking drill bits of 30 mm diam.
or below. For small holes of 6.5 mm diam.
or below, use metalworking drill bits.
7. Mounting drill bits
Tighten drill bits with the chuck wrench. There are
three holes in which the chuck wrench should be
inserted. Tighten them equally in turn at three holes,
without tightening them only at one holes.
8. Confirm the power receptacle
If the power receptacle only loosely accepts the
plug, the receptacle must be repaired. Contact the
nearest electric store for repair service. If such a
faulty receptacle is used, it may cause overheating,
resulting in a serious hazard.
HOW TO USE THE DRILL
1. Pressing force of drill
You cannot get holes quickly even if pressing it by
strong force more than necessary.
It not only damages the tip of drill bits and decreases
the efficiency of operation, but also shortens the
life of the drill.
2. In case of penetrating holes
It is subject to break the drill bits when penetrating.
It is important to decrease pressing force when
penetrating.
3. Switch operation
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.
4. Regarding the drill chuck
The drill chuck is secured to the spindle with a
taper. Should the drill chuck be accidentally detached
from the spindle, deposited on the chuck taper
section and the spindle chuck mount, tap the side
plane of the chuck after retracting its three claws,
and reattach it to the spindle. Carefully handle the
taper section so that its surface does not become
scarred.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch power OFF and disconnect the
plug during 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. 1)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon
brush No. shown in the figure when it becomes
worn to or near the “wear limit”. In addition, always
keep carbon brushes clean and ensue that they
slide freely within the brush holders.
5. Replacing carbon brushes
Disassemble the brush caps (Fig. 2) with a slottedhead screwdriver. The carbon brushes can then be
easily removed.
6. Keeping after use
When not in use, the Electric Power Tool should
be kept in a dry place out of the reach of children.
