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.

Work area safety

1. Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

2. 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 or fumes.

3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.

Electrical Safety

4. 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.

5. 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.

6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.

7. 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.

8. 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.

Personal Safety

9. 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.

10. 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.

11. 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.

12. 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.

13. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.

14. 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.

15. If devices are provided for the connection of

2

dust extraction and collection facilities,
ensure these are connected and properly used.

Use of these devices can reduce dust-related
hazards.

Power tool use and care

16. 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.

17. 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.

18. 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.

19. 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.

20. 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.

21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

22. 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
those intended could result in a hazardous
situation.

Battery tool use and care

23. 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.

24. 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.

25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.

26. 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.

27. 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.

SERVICE

28. 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.

29. Follow instruction for lubricating and

changing accessories.

30. Keep handles dry, clean and free from oil and
grease.

NOTE:

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.

Drilling operation

Drilling in wood

When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled
dry.
First, slide the action mode change lever so that it points
to the

marking. The adjusting ring can be aligned in
any torque levels for this operation. Then proceed as
follows.

CAUTION:

• Pressing excessively on the tool will not speed up

the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.

• There is a tremendous force exerted on the tool/bit

at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.

• A stuck bit can be removed simply by setting the

reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.

• Always secure small workpieces in a vise or similar

hold-down device.

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for

7

15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the

battery cartridge is removed before attempting to
perform inspection or maintenance.
