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.
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.
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.

• Use only a dry, soft cloth for wiping the unit.
Do not use a damp cloth, thinner , benzine,
or other volatile solvents for cleaning.
• In the event that the inside of the tool or
battery pack is exposed to water, drain
and allow to dry as soon as possible.
Carefully remove any dust or iron filings
that collect inside the tool. If you experience any problems operating the tool,
consult with a repair shop.
VII. TIGHTENING
TORQUE
The power required for tightening a bolt will
vary, according to bolt material and size, as
well as the material being bolted. Choose
the length of tightening time accordingly.
Reference values are provided below.
(They may vary according to tightening conditions.)
Factors Affecting Tightening Torque
The tightening torque is affected by a wide
variety of factors including the followings.
After tightening, always check the torque
with a torque wrench.
1) Voltage
When the battery pack becomes near-
ly discharged, the voltage decreases and
the tightening torque drops.

• The following bolts are used.
Standard bolts: Strength type 4.8
High tensile type 12.9
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).
Tightening torque will vary, even with
the same bolting material (e.g. steel),
accord ing to the surface finish.
Torque is greatly reduced when the bolt
and nut start turning together.
5) Socket play
Torque is lowered as the six-sided configu-
ration of the socket of the wrong size is
used to tighten a bolt.
6) Switch (Variable speed control trigger)
Torque is lowered if the unit is used with
the switch not fully depressed.
7) Effect of Connecting Adaptor
The tightening torque will be lowered
through the use of a universal joint or a
connecting adaptor.
