Safety instructions for tightening and loosening
Always observe local regulations and directives
when starting the tool. Always inspect power tool
as to its function and safety condition – never work
with damages tools or objects!
Beware freely rotating accessories (alkitronic®
DMA / STACO / STABI). Loose garments, long
hair, cables etc. must be kept outside the danger
zone / rotation range.
The alkitronic® EAF torque multiplier must never
be operated without supervision. An immediate
stopping must be possible at all times. Observe
safety distances.
6.1.1 Tightening and loosening
Always place the STACO/STABI completely and safely
on the bolt/nut. The support of the DMA to absorb
the reaction torque must always be safe and stable.
Please consult your alkitronic® partner for custom-
ized DMA solutions.
An incomplete or incorrect connection or support
will lead to the following when bolting:
- Possible overload fractures of the STACO / STABI
gear and even drive square
- Incorrect torque application
- Contusions or severe injuries caused by spun off
parts or splinters.
• An improper usage may also render all warranties null and
void.
Reaction torque
Never reach between DMA and support point. High
risk of injuries (contusion)!

Work steps
• Place alkitronic® EAF with STACO / STABI onto the bolt /
nut.
• The DMA must absorb the reaction torque on the level
of the STACO / STABI (S); a stable abutment (G) must be
provided.
• Always hold the torque multiplier perpendicular over
the bolt axis.
• Start bolting action.
• The tool will stop as soon as the set shut-off torque or
entered value has been reached.
Do not retighten bolts/nuts! Because the pre-
set torque is exceeded and it can lead to dam-
age to the torque multiplier or to the screw /
threaded bolt.
alkitronic® EAF model - before moving to the next bolt / nut:
Various torque multipliers from other manufacturers cannot
be removed from the bolt joint (torsional force).
No problem for the alkitronic® EAF model, with
integrated, fully-automatic release function. This
function enables a fast, secure "run free" of the reac-
tion arm (DMA) and also relieves torsional stresses
within the multiplier.
For Information:
When loosening the bolted connection, up to 20% higher
torque (loosening torque) may be required.
• Switch off motor
• Remove machine, place on next bolt/nut
• Start bolting process
