battery powered torque multiplier
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.

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
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.
G
S
Never reach between
DMA
and support point. High
risk of injuries (contusion)!

tightening
Reaction torque
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.

Remove machine, place on next bolt/nut
•
