1)1)
Work areaWork 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)2)
Electrical safetyElectrical 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.

Personal safetyPersonal 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 jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry 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.

Power tool use and carePower 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.
- 5 -
Page 7
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.

１．Adjust tightening torque
○ Graduations of the torque setting dial are just a guidance. Use dial type
torque wrench to adjust torque setting dial if minute torque control is
necessary.

Page 29
○ Tightening Torque may differ by conditions.
Torque setting has to be done daily before operation and when tightening
conditions change.
○ Make sure the tightening direction of SIMPLE TORQON when tightening
reverse thread bolts/nuts.
○ In order to prevent malfunction as well as over torque, never tightening the
same bolts/nuts twice.
２．Tendencies that tightening torque may differ
Tightening torque varies depending on tightening conditions.
Tendency shown as below.
Factors at Tightening Conditions Possibility
- When connection is soft (gasket, rubber, glass & etc in
between the steels)
- When bolt length is extremely long,
- When bolt grades are under 8.8 or 10.9
- When friction coefficient of the bolt is high
- When bolt or washer is stripped during tightening
- When voltage is higher than rated voltage of the wrench
- When connection is hard
- When bolt diameter is large
- When bolt length is short
- When water or oil is adhered on the bolt
- When tightened bolt is tightened again (over tightened)
- When voltage is lower than rated voltage of the wrench

○ Accidental starting invites serious injury.
① Clean dust and debris from impact socket and square drive periodically.
② Use only a damp cloth to clean your SIMPLE TORQON and impact sockets
since certain cleaning agents and solvents are harmful to those parts. Some
of these include: benzene, thinner, gasoline and etc.
③ Never put solvents into the exhaust vent.
④ Store SIMPLE TORQON in the metal case after operation and keep it dry.
⑤ Carbon-brush must be regularly inspected and replaced with the new
genuine carbon brush when brush length become less than 6mm.
*Carbon brushes are placed in two positions.
*Indicate the wrench model when carbon-brushes are needed because carbon-brush
differs from model to model.

⑥ Replace carbon brush as shown in the following figure.
⑦ Overhaul must be carried out every 6 months or 30,000 tightening,
whichever comes first. Contact your distributor for overhaul.
