6. Mechanical Operation
6.1 Safety Instructions for Tightening and Loosening
Always observe local regulations and directives when
starting the tool. Always inspect power tool to make
sure that it can safely function. Never work with
damaged tools or objects.
Beware freely rotating accessories. Loose garments,
long hair, cables, etc. must be kept outside the
danger zone / rotation range.
The ABG Nutrunner must never be operated without
supervision. Immediate stopping must be possible at
all times. Observe safety distances.
6.1.1 Tightening and Loosening
Always place the socket/connector completely and
safely on the bolt/nut. The support of the reaction bar
to absorb the reaction torque must always be safe
and stable. Please consult your AIMCO partner for
customized reaction bar solutions.
An incomplete or incorrect connection orsupport will
lead to the following whenbolting:
– Possible overload fractures of the socket/connector,
gear and even drive square
– Incorrect torque application
– Contusions or severe injuries caused by spun-off
parts or splinters.
Improper usage may also render all warranties null and void.
Never reach between reaction bar and support point.
Doing so presents a high risk of injury.
Work steps
•Place the ABG nutrunner with socket/connector onto the
bolt/nut.
•The reaction bar must absorb the reaction torque on the
level of the socket/connector (S); a stable abutment (G)
must be provided.
•Always hold the nutrunner 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.
Before moving to the next bolt / nut:
•If the torque multiplier cannot be pulled off the bolted
joint (torsional forces caused), change the direction of
rotation and switch the tool on and immediately off again
to release the tool.

7.1 Visual and Mechanical Inspection
Battery packs, charger station, operating and display
elements, case and accessories, such as reaction bars,
mustberegularlyinspected for damages and must be
replaced professionally if necessary.
Do not obstruct ventilation opening. Soiled or
blocked ventilation openings can cause malfunction
and damage to the motor.
In case of reduced power, strong gear noise, or
obvious severe damage, immediate repair is
necessary. Please send all devices to be repaired in
their original packaging to your nearest AIMCO
partner.
8. Servicing / Storage / Maintenance
8.1 Replacing Accessories
See section 4.2 Preparing for Work with the Power Tool.
Follow steps in the opposite direction.
8.2 Storage in Lockable Containers
Store ABG Nutrunners and the charger station in a dry
and cooled-off state in the original case, or in any
other closable container. Heat and moisture lead to
oxidation of the gear and other components inside
the case. This can cause the tool to malfunction and
can cause damage to the electronic circuitry and
motor. When storing, ensure that the charger station
power cable is not squeezed anywhere or damaged
in any way.
Notes for the Li-Ion rechargeable battery pack:
Always remove the battery pack from the power tool
when not in use. Do not touch or short the contacts.
Although the electronic circuitry will protect the
battery packs against complete discharge, a long life
is best ensured by maintaining a sufficient charge in
the battery pack.
LED display on the battery pack
In order to maintain the battery pack in a fully charged
state, a trickle charge of about 70 to 75% is required
(see illustration above).
8.3. Decommissioning
If the AcraDyne tools and devices are not used over
an extended period of time, they should be cleaned
and stored in a dry and closable space that is
inaccessible to children. The optimum storage
temperature is between 10° and 30° C (50° and 86° F).
Rotating components must be protected against
oxidation (see Section 8.2).
8.4 Service and Maintenance
The ABG Nutrunner is an extremely powerful and
robust product. To ensure long life and reliability over
many years, the machine must be serviced at regular
intervals (performance check, motor check, safety
inspection, and calibration service).
Service intervals
The power tool must be inspected at least once per
year. In the case of high usage or excessive operating
hours, servicing and calibration will be necessary
more frequently. In the case of unusual gear noises, a
gear lubrication is urgently recommended to prevent
subsequent damage.
AcraDyne ABG Nutrunners must always be packed in
the original packaging when sending items in to your
AIMCO partner or AIMCO.

9.1 Safety Shut-Off
In order to prevent faulty boltings or damages to the
power tool, the AcraDyne AGB Nutrunner is fitted
with a multi-functional monitoring system.
If the machine switches itself off, the electronic system has
activated the self-protection mode. There is an audible warning
(30-second tone or until the push button (D) is released) (Fig. 3).
9.2 Causes and Problem Solving
Battery pack almost empty
The electronic system protects the battery pack against
complete discharge.
If the LED display (L, Fig. 4) flashes, the battery pack is almost
empty. If necessary, press the button on the battery pack (8, Fig.
4) to check the charge state. If the battery pack is almost empty,
it must be recharged.
See also Section 4.1.2 Battery Pack, Capacity, and Signal Display
Excessive temperature
Overheating of the power tool over an extended period of time
will result in temperature switch-off. The tool or the battery pack
must be cooled down.
If the battery pack is very warm to the touch, it is
recommended to cool it in the charger station. The
motor will cool down quicker in idle mode.
Excessive current increase
The power tool switches off automatically.
If the current increase is quick (such as when there is a sudden
blockage or seizing) the tool is switched off. Switch off the
power tool on the push button (D, Fig. 3). Then restart and
continue working normally. Prevent further blockages.
10. Noise Level and Vibration
Permanent noise level measured at maximum idle speed:
76 dB(A)
Noise emissions were measured at various working cycles. The
distance of the sound sensor was 1 m from the geometric center
of the power tool.
Vibration: medium until just before reaching the preselected
torque.
11. Environmental protection
Do not immerse battery packs in water.
Protect the environment and do not dispose of
electrical power tools and battery packs in normal
household waste. Observe national regulations
regarding recycling, and separation of unusable
machinery, accessories, and packaging. Secure the
contacts against shorts (e.g. cover with PTFE).
