alkitronic®/ Einhell Charging station 220-250 V / 50-60 Hz /
max 95 W, output 20 V / 4,0 A (d.c.)
Important! According to special provision 188, the
lithium-ion battery must always be set to 4 Ah (72
Wh) before it can be shipped or transported! Faulty
lithium-ion batteries must never be shipped in the
ordinary mail! Please contact alkiTECHNIK GmbH or
your alkitronic® partner.
3. Start-up Li-Ion Battery
3.1 Changing of the battery capacities
The alkitronic®/ Einhell Li-Ion battery pack can be switched
between two capacities (4 Ah/6 Ah)
- 4 Ah (72 Wh) --> better for the battery, extending its total
life by about 3 times
- 6 Ah (108 Wh) --> long operating time per battery charge
The battery is supplied with 4 Ah (72 Wh).
Press the battery charge level
indicator button (A) briefly.
The display (B) for the battery
charge level indicator initially
B
A
Fig 1
displays the charge status in % and then the current set charge
level consecutively for 2 seconds each.
This process is essential in order to avoid switching over
inadvertently.
Battery charge
level indicator
Important!
The charge status adjusts automatically after a switch
to 4 Ah or 6 Ah and can dier from the previous set-
ting. If the battery has a charge status of 100 % when
set to 4.0 Ah, for instance, and is then switched to 6.0
Ah, the charge status will fall to signicantly less than
100 %. You will need to recharge the battery.
Do not use defective or deformed battery packs!
Do not open battery packs! Do not touch or short-
circuit the contacts! Keep small metal objects away
that could cause bridging of the contacts. A short
circuit can cause re and burns.
A slightly acidic, ammable liquid can escape from
defective Li-Ion battery packs!
If battery uid leaks out and comes into contact
with your skin, rinse immediately with plenty of
water. If battery uid gets into your eyes, wash
them out with clean water and seek medical at-
tention immediately!
Never charge non-rechargeable batteries. Danger
of explosion!
Do not recharge a fully charged battery pack!
Do not insert any objects into the ventilation of the
alkitronic® EB-S housing or the charging station -
risk of short circuit or electric shock !
3.2 Hazard warnings alkitronic®battery pack
Protect battery packs (1) from moisture
and do not expose to re!
• The battery can only be switched if the number 4 or 6 is
pressed. Other numbers do not have any signicance.
Proceed as follows for the settings:
Important! Read the instructions through com-
pletely before changing the battery setting!
• Hold the button (Fig. 1) for the battery charge level indi-
cator (A) down for about 6 seconds until the battery on
the display (B) begins to count from 1 to 9.
• To switch from 4 Ah to 6 Ah, press the button (A) brie y again
when the number 6 is displayed. The count then continues
as normal to 9.
• To switch from 6 Ah to 4 Ah, press the button (A) brie y again
when the number 4 is displayed. The count then continues
as normal to 9.
• Once the display (B) has reached 9, the new setting“6Ah”
or“4Ah”will be indicated for about 2 seconds.The battery
is now switched and ready for use.
When bolting, we recommend using the battery pack
with the preset of 4 Ah, as the performance of the
alkitronic®EB-S is optimized for this setting.
It is therefore not necessary to change to 6 Ah to achieve
the maximum torques
Advice
In order to further increase the number of bolted
joints, the charging of the battery pack can be car-
ried out at a 6 Ah setting, thus achieving a maximum
state of charge. As soon as the charging process is
nished, set the capacity back to 4 Ah!

EB-S Battery driven Torque Multiplier
6. Mechanic Operation alkitronic® EB-S
The alkitronic®EB-S electric torque multiplier must
not be damp, neither operated nor stored in moist
or humid environment. Otherwise an additional
rain protection must be provided on site.
6.1 Placing tool in operation
alkitronic® STACO/STABI/STA/DMA (specic nuts,
connectors, adaptors and reaction absorbers) avail-
able as accessories, are needed in accordance with
a specic bolt joint.
The alkitronic® EB-S must be disconnected from
the battery pack before making any changing ac-
cessories.
• Accessories may be placed on the tool drive side. Make
sure every part is placed correct and secured (in compli-
ance with item 6.2 Preparing for bolting).
• Replace worn or damaged accessories immediately. For
replacement use original alkitronic® accessories only.
This rule will reduce the risk of malfunction and serious
personal injury.
• Put STACO / STABI (2)/(3) on square drive (both boreholes,
adaptor and square must correspond),
• insert safety pin (7), secure with rubber ring (6).
• STABI: turn in safety screw (8) completely.

We strongly recommend
running the alkitronic® EB-S in at idle speed, at
high torque setting for 30 seconds before use.
Thus, among other things, the operating greases
are brought to viscosity, the moving parts to
operating temperature, and a higher degree of
eciency is achieved.
The torque values according to the calibration
certicate are thus reproduced as accurately as
possible from the very rst bolting operation.

Operation steps alkitronic®EB-S
The battery is already tted and the bolting parameters have
been set:
• Place the alkitronic® EB-S 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.
• Use the rocker switch to trigger the bolting process in the
right direction of rotation.
• The drive stops when achieving the desired torque or value.
Place alkitronic® EB-S on the next bolt/nut
If the automatic release function is not set and the torque
multiplier is not removable of the bolted joint (torsional
forces caused):
• Briey switch on the alkitronic® EB-S with the rocker button
Direction of rotation left until the DMA (reaction arm) is free.
Release the rocker button
• Place the machine on the next bolt/nut and repeat the
tightening process.
For your information: For loosening, a signicantly higher
loosening torque (depending on the bolt joint, up to 50%)
may be necessary than the torque originally applied during
tightening.
Active automatic release function:
• If the tension release function is preset, the DMA is auto-
matically„released“. Then place the alkitronic® EB-S on the
next bolt/nut and continue the bolting process.

Always place STACO/STABI completely on the bolt/
nut. Provision of a safe and stable counter mount-
ing is essential. For individual DMA solutions, your
alkitronic® Partner will be pleased to assist you.
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.
In addition, non-compliance of any above items will void
all warranty claims.
6.3 Safety instructions operation
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 unat-
tended 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.

EB-S Battery driven Torque Multiplier
Do not retighten the nut/bolt.
Because the preset torque is exceeded and it
can lead to damage to the torque multiplier or
to the bolt / threaded bolt.
• End of the bolting process
If the bolting process was error-free („OK“ - shown in the
display), conrm the process.
• Remove the alkitronic® EB-S, another bolting process can
be started.
Application release function:
This is not intended for loosening a bolt/nut. Use
the automatic release function only to release ten-
sion inside the alkitronic® EB-S .
7. End of Work / Interruption / Cleaning
Place the alkitronic® EB-S on a at, dry surface - out
of reach of children. Remove the battery pack.
Keep the ventilation slots and motor housing regularly free
of dust and dirt. Clean the unit with a damp, clean cloth or
blow it out with compressed air at low pressure.
Do not use any cleaning agents or solvents; which could at-
tack the plastic parts of the alkitronic®EB-S. Make sure that no
water can get into the housing. Water penetration increases
the risk of damage to the electronics.
8. Functional and Operational Tests
8.1 Optical and mechanical inspection
Check for intactness regulary, power cord and plug
(Charger Station), display and operating elements,
gear box, drive element, housing and accessories
(e.g. reaction absorber DMA, adaptors). Before
further use of the alkitronic® EB-S, damaged parts
should be properly repaired or replaced. Serious
damages 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® EB-S (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!
Loosening the bolted joint
In principle, measures and operating behavior are largely iden-
tical to those for tightening, e.g. ensure a stable counter-mount
and correct reaction point; keep the torque multiplier in axis
line to the bolt, etc.
For loosening, however, a signicantly higher loosening tor-
que (depending on the bolt joint, up to 50%) may be neces-
sary than the torque originally applied during tightening.
If the torque multiplier cannot loosen the bolt joint
and it switches o automatically for safety reasons -
do not press the pushbutton again.
The torque can build up disproportionately and
cause damage to the gear unit!
If the bolt/nut cannot be opened with the preset torque,
interrupt the loosening process!
Change the direction of rotation and start the torque multiplier
briey to relieve torsional stresses in the torque multiplier.
Then set the next higher torque in the operating area. Torque
multiplier with direction of rotation ccw - start loosening
process again.
In case the torque is not sucient even at the highest torque
level - to loosen the bolt/nut - change to a stronger alkitronic®
product.

Operation and Maintenance Manual
9.4 Maintenance intervals
The alkitronic® EB-S is an extremely ecient and
robust product. Nevertheless to ensure lifetime
and performance for years, a regular maintenance
is necessary (Performance-Check, Motor-Check,
Safety-Check, Calibration-Service).
Maintenance periode / Service
The torque multiplier must be submitted at least
once a year for inspection.
After high stresses/loads or also hours of opera-
tion a calibration and servicing
must be carried out in shorter
periodes. In this case a service
warning appears in the display
to remind the user. Acknowl-
edge the message with the “M”
button. From this time on the information is shown
at every restart of the torque multiplier.
9. Storage / Maintenance / Service
9.1 Accessories change
Note item “6.2 Preparing for bolting“ and carry out
the described steps in reverse order.
9.2 Storage
The alkitronic® EB-S should be stored dry, cooled
down and dust-free in alkitronic original packaging
or in other lockable containers. Warmth and humid-
ity may lead to oxidations in gear parts as well as in
other parts within the tool housing. Following these
rules will reduce the risk of malfunctions, electronics
and motor damage. when storing, make sure that the
battery pack is removed from the alkitronic®EB-S.
9.3. Taking out of operation
In case that the alkitronic® EB-S is stored for a pro-
longed period of time:
Store the tool cleaned in a closeable dry room, out
of the reach of children. Avoid excessive exposure to
heat and moisture. Moving/rotating tool parts are to
be preserved against Oxidation.

In addition to the number of operating hours, the
number of bolted joints is also a major factor in the
use of the alkitronic® calibration service.
The table shows a type-specic number of bolted
joints from which an inspection is to be carried out.
Upon unusual gear or bearing noises, a lubrication
of the transmission parts is urgently recommended
in order to exclude consequential damage.
In the event of repairs the alkitronic®EB-S must be
senttotheappropriatealkitronic®Partnerordirectly
to alki Technik GmbH in original package.
10. Technical Notes
Notes on the safety shut-o
In order to avoid faulty bolted connections and/or
bolt damage, each alkitronic® EB-S is equipped with
a temperature-controlled safety shut-o. When the
shut-o is active, the letters “O” ash in the O-LED
display in the operating area. After a short cooling
time, the alkitronic® EB-S is ready for use again (“O”
no longer ashes).
11. Acoustic Emission and Vibration
Sound pressure level at max. idling speed:
Models alkitronic®EB-S 75 - 80 dB(A)
Sound pressure levels were measured for dierent work cycles,
with the sensor positioned at a distance of 1 m to the geometric
centre of the machine.
Low vibration shortly before reaching the pre-set torque.
12. Environmental Protection
Do not throw battery packs into water or dispose
of them in lakes / natural landscapes.
Protect the environment and do not dispose of
power tools, equipment and battery packs in
household waste. Follow national regulations for
separate collection and recycling of disused ma-
chines, packaging and accessories.
Discharge the battery pack in the power tool be-
fore disposing of it. Secure the contacts against
short-circuiting (e.g. insulate with adhesive tape).
