Prior to electric power connection, it must be
ensured that the indicated technical data on the
tool type plate as well as in the operation manual
corresponds with the power supply and environ-
mental conditions. Deviating values could lead to
malfunctions or severe damages.
All alkitronic® electric torque multipliers are deliv-
ered with a three-wired power cord with ground
conductor. A possible exchange of the power cord
plug (caused by nationally different electricity
supply or net plugs) may be performed only by an
authorized electrician. See appendix “Replacing
the power cord plug“.
alkitronic® electric torque multipliers must not
be damp, neither operated nor stored in moist or
humid environment. Otherwise an additional rain
protection must be provided on site.
In case of machine malfunction or loss of electricity
immediately switch o power button and discon-
nect the plug from the power source.
3.1 Placing tool in operation
alkitronic® STACO/STABI/STA/DMA (specic nuts, connectors,
adaptors and reaction absorbers) available as accessories, are
needed in accordance with a specic bolt joint.
The torque multiplier must be disconnected from
the power source before making any adjustments
or changing accessories.
• Accessories may be placed on the tool drive side. Make
sure every part is placed correct and secured (in compli-
ance with item 3.2 Preparing for bolting).
• Replace worn or damaged accessories immediately. F or
replacement use original alkitronic® accessories only.
This rule will reduce the risk of malfunction and serious

During operation, the item 5.3 Operation Tight-
ening and Loosening (from page 18) must be
observed.
If the alkitronic® EF is only operated via the FB-
EF, make sure that the tool is mechanically safe
and stable at the place of use. It must always be
ensured that the EF torque multiplier is ready to
be switched o.

Operation steps alkitronic® EF-S / EF-A
• Connect the torque multiplier to the power supply.
• Place the alkitronic® torque multiplier with alkitronic®
STACO/STABI completely on bolt/nut.
• The DMA or torque-on recipient of the torque multiplier
must be at the same height as the socket/adaptor to take
the reaction moment.
• A sure, stable counter-mount (2) must be ensured.
• Always keep the torque multiplier in axis line to the bolt
during bolting process.
Parameters are already set:
• Push power switch and start bolting process.
• The drive stops when achieving the desired torque or
value. Switch off machine and place on next bolt/nut.
Place on the next bolt/nut alkitronic® EF-S / EF-A
• If the automatic release function is not set and the
torque multiplier is not removable of the bolted joint
(torsional forces caused):
Release the torque multiplier by changing the direction
of rotation and briey press the ccw button until the
DMA (reaction arm) is free.
• For Information:
When loosening the bolted connection, up to 20%
higher torque (loosening torque) may be required.
• Switch o machine and place EF multiplier on next bolt/
nut and start bolting process.

ing is essential. For individual DMA solutions, your
alkitronic® Partner will be pleased to assist you.
In addition, non-compliance of any above items
will void all warranty claims.
Improper bolting connection or incorrect reaction
support may cause:
- Strain breakage in STACO / STABI adaptors,
bearing or output square drive;
- Bruises or even life-threatening injuries (parts
splintering o);
- “Shut-o“ torque failures.
5.3 Tightening and loosening
Safety hints
Comply with all applicable local, state and national
electrical and safety regulations.
Always carry out a function inspection and safety
check - no working with damaged parts!
Keep your hair, clothing, and gloves away from
moving parts. Loose clothes, jewellery or long hair
can be caught in moving parts (alkitronic® DMA/
STACO/STABI/STA).
Maintain a safety distance when tightening bolts or
nuts. Do not leave the torque multiplier unattended
during use. A rapid“switch o”in case of emergen-
cy must be always ensured.
Keep proper footing and balance at all times. This
enables better control of the torque multiplier in
unexpected situations.

5.3.2 Tightening and loosening - alkitronic® EF-R / EF-SG
When using alkitronic® EF-R models the reaction
pin (4) must be put completely into the receiving
device. Otherwise there is a danger of case break-
age and a risk of serious personal injury.
The output drive of the alkitronic® EF-R and/or
EF-SG takes place via a xed width across at (AF).
For the reduction to smaller spanner openings an
alkitronic®STA (3) is necessary. For proper operat-
ing use alkitronic® accessories only!

7. Functional and Operational Tests
7.1 Optical and mechanical inspection
Check for intactness regulary, power cord and
plug, display and operating elements, gear box,
drive element, housing and accessories (e.g. reac-
tion absorber DMA, adaptors). Before further use
of the torque multiplier, damaged parts should
be properly repaired or replaced. Serious dam-
ages and many accidents are caused by poorly
inspected tools.
In causes of performance loss, strong gear noises
or recognisable heavy damages a repair is to be
carried out immediately. In the event of repairs
the alkitronic® torque multiplier (in original pack-
age) must be sent to the appropriate alkitronic®
Partner or directly to alki Technik GmbH.
The following operation and service requests should be
strictly observed!
