I. 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 and battery operated
(cordless) power tool.

SAVE THESE INSTRUCTIONS

Work Area Safety

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

1) 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.

2) 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.

3) Do not expose power tools to rain or

wet conditions.

Water entering a power tool will increase
the risk of electric shock.

4) 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.

5)

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.

6)

If operating a power tool in a damp
location is unavoidable, use a residual
current device (RC D) protected
supply.

Use of RCD reduces the risk of
electrical shock.

Personal Safety

1)

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 personal injury .

2) 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.

3) 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 the power tools
that have the switch on invites accidents.

-

5 -

4) 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.

5) Do not overreach. Keep proper

footing and balance at all times.

This enables better control of the power
tool in unexpected situations.

6) 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.

7) 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.

Power Tool Use and Care

1)

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.

2) 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.

3) 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.

4)

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.

5) 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.

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

7) 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

1) Ensure the switch is in the off position
before inserting battery pack.

Inserting battery pack into power tools
that have the switch on invites accidents.

2) 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.

3) Use power tools only with specifically

designated battery packs.

Use of any other battery packs may
create a risk of injury and fire.

4)

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.

5) Under abusive conditions, liquid may

be ejected from 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

1) Have your power tool serviced by a
qualified repair person using only
identical replacement parts.

This will ensure that the safety of power
tool is maintained.

operating condition, since it does not have
to be plugged into an electrical outlet.

3)

Hold power tools by insulated grip-

ping sur faces when performing an
operation where the cutting tool may
contact hid den wiring.

Contact with a “live” wire will make ex-

posed metal parts of the tool “live” and
shock the operator.

4) If the bit becomes jammed, immediately
turn the trigger switch off to prevent an
overload which can damage the battery
pack or motor. Use reverse motion to
loosen jammed bits.

5) Do NOT operate the Forward/Reverse
lever when the trigger switch is on.

7) Do not strain the tool by holding the
speed control trigger halfway (speed
control mode) so that the motor stops.
The protection circuit will activate and
may prevent speed control operation. If
this happens, release the speed control
trigger and squeeze again for normal
operation.

8) Be careful not to get dust inside the
chuck.

9) Do not touch the rotating parts to avoid
injury.

10)

Do not use the tool continuously for a long
period of time. Stop using the tool from time
to time to avoid temperature rise and heat
overload of the motor.

11) Do not drop the tool.

(3) Overheat warning lamp

.

• If the overheating protection feature
activates, allow the tool to cool
thoroughly (at least 30 minutes). The
tool is ready for use when the overheat
warning lamp goes out.

• Avoid using the tool in a way that
causes the overheating protection
feature to activate repeatedly.

• If the tool is operated continuously
under high-load conditions or if it is
used in hot-temperature conditions
(such as during summer), the
overheating protection feature may
activate frequently.

• If the tool is used in cold-temperature
conditions (such as during winter) or if
it is frequently stopped during use, the
overheating protection feature may not
activate.

• The performance of the EY9L42
deteriorates significantly at and below
10°C due to work conditions and other
factors.

• The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C
(32°F), the tool may fail to function
properly.

• Use the charger at temperatures
between 0°C and 40°C, and charge the
battery at a temperature similar to that
of the battery itself. (There should be no
more than a 15°C difference between
the temperatures of the battery and the

charging location.)

Battery protection

feature active

Excessive (complete) discharging of
lithium ion batteries shortens their service
life dramatically. The driver includes a
battery protection feature designed to
prevent excessive discharging of the
battery pack.

• The battery protection feature activates
immediately before the battery loses its

charge, causing the battery low warning
lamp to flash.

• If you notice the battery low warning
lamp flashing, charge the battery pack
immediately.

• If it is started with too little battery power
remaining, the tool may stop operating
without the battery low warning lamp
flashing first. This indicates that there is
too little battery power remaining to use
the tool, and the battery pack should be
charged before further use.

• If the tool is subject to a sudden load
during use that causes the motor to lock
up, the over current prevention sensor
may be triggered, and the impact power
select display may flash. The lamp will
stop flashing once you address the
cause of the motor’s locking up and
cycle the trigger.

Recommended Grip

Use the grip to hold and operate the driver
with one hand. If the job requires additional
force, you can push against the rear end of
the driver with your other hand.

2) Tightening time
Longer tightening time results in increased

tightening torque. Excessive tightening,
how ever, adds no value and reduces the
life of the tool.

3) Different bolt diameters
The size of the bolt diameter affects the

tight ening torque.
Generally, as the bolt diameter increases,
tightening torque rises.

4) Tightening conditions

Tightening torque will vary, even with the
same bolt, according to grade, length, and
torque coefficient (the fixed coefficient indi­cated by the manufacturer upon produc­tion).
