ETD ST81-120-13-T75 Safety Information
© Atlas Copco Industrial Technique AB - 9836 3060 00 3
Notice
Many events in the operating environment may af-
fect the tightening process and shall require a vali-
dation of results. In compliance with applicable
standards and/or regulations, we hereby require
you to check the installed torque after any event
that can influence the tightening result. Examples
of such events include but are not limited to:
• initial installation of the tooling system
• change of part batch, bolt, screw batch, tool,
software, configuration or environment
• change of air- or electrical connections
• change in line ergonomics, process, quality
procedures or practices
• changing of operator
• any other change that influences the result of
the tightening process
The check should:
• Ensure that the joint conditions have not
changed due to events of influence.
• Be done after initial installation, maintenance
or repair of the equipment.
• Occur at least once per shift or at another suit-
able frequency.
Safety and operating
instructions
Safety instructions
Warning / Important
• Make sure you are familiar with the operator’s
instructions before you use this tool.
• The tool together with any attachments or ac-
cessories, must never be used for anything
other than the designed purpose.
• All locally legislated safety rules regarding in-
stallation, operation and maintenance shall be
respected at all times.
• This product is only intended for industrial use
and shall only be operated indoor in dry rooms.
This product must not be used in explosive at-
mospheres.
• Only use power sockets.
• Keep hands, long hair and other objects away
from the rotating socket.
• Do not use gloves.
• When using a suspension yoke, check that it is
in good condition and correctly fastened.
• Be prepared of the reaction force which will
occur when the tool is used.
• Make sure that the tool is in good working or-
der and that the controller is correctly pro-
grammed before use to avoid unexpected be-
haviour from the tool which may result in oper-
ator injury.
• ETD / ETP nutrunners are used together with a
torque reaction bar. Please be aware of the rota-
tional direction of the spindle before starting
the tool, the reaction force may work in an un-
expected direction with risk of crush injuries.
• Never put your hand near or close to the reac-
tion bar while the tool is being used.
• If a PLC or similar is used to change the rota-
tional direction of the spindle the tool must be
fixtured to avoid risk of personal injury.
• The tool with its drive/controller box is de-
signed to operate at any setting within its
torque range at a primary voltage of nominal
230V/50Hz alternatively 115V/60Hz, single
phase. Refer to the manual for Your POWER
FOCUS or Drive unit.
• Check function of the earth fault protector and
ground loop continuity on regular basis accord-
ing instructions in the drive/controller ASL.
• Always keep the POWER FOCUS/drive unit
locked.
• Always make sure that the POWER FOCUS/
drive is switched off before connecting/discon-
necting the tool cable.
• Always disconnect the tool from the POWER
FOCUS/drive unit before making any adjust-
ments on or inside the Tool.
• Refer installation and servicing to qualified
personnel only.
• For proper reference between product and in-
struction, note the Tool serial numbers here:
General information
General information
The TENSOR-system consists of a range of tight-
ening tools powered by brushless electric motors,
and individual, all-electronic control and drive

units. Motors are available in different sizes.Note
that only tool and drive unit with same designation
ST31, ST61, ST81 or ST101 can be operated to-
gether!
All tools are protected from overheating the motor
by a device which cuts the power if the tempera-
ture rises abnormally.When the temperature goes
down again, the overheat protection device resets
automatically.
Electrical protection of the system is based on two
parallel, mutually independent systems.One is
passive and earths the entire equipment: The other
is active and takes the form of an earth fault circuit
breaker EFP. The latter senses small current leak-
age (>30mA) and should such leakage occur,
switches off the drive unit (<30ms).
Changing, interfering or tampering with the pro-
tective systems voids all warranty and obligation
from Atlas Copco.
Trouble-shooting and re-start of the system may
only be carried out by an authorized person.
Control the function of the Earth fault protector on
a regular basis by pressing the trip-button. The
EFP should switch off according. Also check the
continuity of the ground loop from the tool body to
proper earth. This control is recommended to be
carried out at least once every month.

Installation
Installation
The tool should, via its correct POWER FOCUS/
drive unit, be connected to the mains, 230V/ 50Hz
alternatively 115V/ 60Hz, single phase.See in-
structions for your POWER FOCUS/ drive unit.
Fitting of the tool cable:
• Security check that the cabletype is correct
• Align the cable connector using the two asym-
metrically positioned heads on the connector to
fit in the slots in the tool handle.
• Tighten the lock nut.

• Security check that the connection is correct by
pulling, pushing and turning the cable connec-
tor (there should be no movement).
The tool has a built in electronic memory chip
that will transmit the torque transducer calibra-
tion value and angle pulses to the POWER
FOCUS/drive unit. Any changes made of these
values in the POWER FOCUS while the tool
is connected will be stored in the tool memory.
Grounding
If the tool is mounted in a handheld or handguided
fixture, the fixture should be connected to the drive
using a separate 2.5mm2 grounding cable.
Handling
Operating
As tightening torque increase the reaction force
build up equally. Make sure that the tool is in cor-
rect working order and that the controller is cor-
rectly programmed to avoid unexpected behaviour
from the tool, which may result in operator injury.
ETV/ETD: Check that the tool is in the correct
running direction by turning the reverse ring,
• Clockwise = Tool forward.
• Anti clockwise = Tool reverse
ETP: Check that the tool is in the correct running
direction by pushing the revers switch.
The soft-start function facilitates entering the
screw head and thread.
The duration of the soft start is adjustable, see the
manual for the POWER FOCUS/ drive unit.
The tool is equipped with signal lights,
• Green = OK tightening.
• Yellow = Warning – low torque.
• Red = Warning – high torque.
Preventing ESD problems
The components inside the tool and controller are
sensitive to electrostatic discharge. To avoid future
malfunction, make sure that service and mainte-
nance is carried out in an ESD approved work en-
vironment. The figure below shows an example of
an appropriate service work station.
Maintenance
Lubrication
Planetary gears, needle bearings and ball bearings
must be lubricated with soft grease containing
molybdenumdisulphide at the regular overhaul of
the tool.
Take care to use specified quantity. Too little as
well as too much will cause problems.

Overhaul and preventive maintenance is recom-
mended at regular intervals once per year or after
maximum 250.000 tightening depending on which
occurs sooner. More frequent overhaul may be
