Foreword
Congratulations on your purchase of an alkitronic®M-ML/
Norwolf Missing Link / Z series / XCE Link (manual) torque mul-
tiplier. This product sets the highest international standards
for quality and safety. To maintain these standards, read and
follow the information and instructions found in the opera-
tion and maintenance manual.
Maintenance and repair of the alkitronic®/ Norwolf man-
ual torque multiplier must be performed by the alki
TECHNIK GmbH or by certied workshops trained and in-
structed by alki TECHNIK GmbH.
Improper maintenance may endanger you and damage the
unit. Non-compliance with any of the above items voids all
warranty claims!
The Operation and Maintenance Manual contains all basic
information and instructions. The operator must read, un-
derstand, and observe this material together with the basic
precautions before either using or attempting to maintain
the alkitronic® / Norwolf manual torque tools.
The Operation and Maintenance Manual must always be avail-
able on site.
This Manual applies only to the alkitronic®M-ML/Norwolf
Missing Link / Z series / XCE Link manual torque multiplier.
Observe the “Safety information” found in section 2, and all
other special instructions in other sections.

A Incoming Inspection and Packaging
Visually inspect all components for possible dam-
age. If shipping damage is found, notify the forward-
ing alkitronic®Partner immediately. Return com-
ponents and alkitronic® / Norwolf manual torque
multiplier in original package to avoid additional
damage. Therefore, please keep the packaging.
B General Description
alkitronic®M-ML /Norwolf Missing Link and Z series are manual
operated torque tools. They are the ideal tools for energy
independent precise tightening and loosening of heavy-duty
bolt connections even in high explosion-risk areas. The XCE
link must always be powered by an electric or pneumatic
Torque Multiplier. The alkitronic®/ Norwolf torque tools
provide safe, economic, and problem-free operation. They
replace pipe extensions and other inadequate methods.
alkitronic®/ Norwolf torque tools are maintenance-free,
compact and robust design. They improve on-the-job safety
and require short assembly times.
• Low energy input - high torque transfer !
1. Safety Instructions
Safety Precautions: Users must not be under the inuence
of intoxicating substances, e.g. drugs, alcohol, medication.
To avoid injuries, always wear safety goggles and protective
clothing when using power tools.
1.1 Intended use
The alkitronic® / Norwolf torque tool has been designed for
tightening and loosening heavy duty nuts and bolts by using
a torque wrench (alkitronic®M-ML /Norwolf Missing Link / Z
series) or electric / pneumatic torque multiplier (XCE Link).
Any other use is considered improper. Any damages resulting
from improper use are the responsibility of the user.
1.2 Operators responsibilities
The user is obliged to read the operating and maintenance
instructions before using or servicing the device. The device
must only be used by persons aware of the purpose, the con-
sequences of their action, and the precise usage of the device.
Please contact your alkitronic® partner for guidance when
ever you are in doubt as to the operation and / or proper
safety precautions to be taken for your particular application.
alki TECHNIK GmbH cannot be held responsible for any
damage caused by improper use, lack of maintenance, or
incorrect application.

2. Operation instructions
Depending on the working environment and the application
of the alkitronic® M-MT/Norwolf Missing Link, Z series or XCE
Link, existing locally regulations can prescribe protective
items (e.g. safety shoes, helmet etc.). Nonobservance of such
regulations can cause serious physical damage (e.g. bruises,
head injury from ying metal parts).
2.1 Preparing for bolting
Setting the rotation (tightening / loosening)
• The rotation is changed by reversing the torque tool by
1800. The bolting direction is marked at the housing.
• To tighten, make sure side engraved“TIGHTEN”is face up.
• To loosen, make sure side engraved“LOOSEN” is face up.
Insert drive and following
the direction of the engraved
TURN arrow, as input is turned,
output will also turn.
2.2 Putting into operation
alkitronic® M-MT /
Norwolf Missing Link
Place the alkitronic® M-MT/ Norwolf Missing Link on the appli-
cation by using the engraved arrows as a guide.
• Place the alkitronic®M-MT/NorwolfMissingLink completely
on the bolt / nut (Fig.1/1 ).
• Ensure a stable reaction point (see page 6, item 3).
• Always keep the tool in axis line (2) to the bolt during the
bolting process.

3. Reaction points / support positions
Safe and stable counter mounting is essential.
Improper support may lead to damage to the tool
or injury to the operator due to the high reaction
forces generating from the tool.
3.1 Reaction support
alkitronic® M-ML / Norwolf Missing Link / Z series or
XCE Link
Reaction support surface (tightening)
Manually push the Link Housing against a solid object (nor-
mally the next nut). Locate a secure system component or a
stationary reaction point.
Fig. 5
Fig. 6 Fig. 7
Fig. 8
Correct support!
Incorrect support!
To protect housing
during excessive use,
slide an aluminum shim
(1) between housing and
reaction point.
Punctual loadings or
sharp-edged counter
mountings may cause
damage to the housing.
Support correct / incorrect
Dangerous tipping can be caused by the bolting
connection and the manual torque multiplier being
at dierent heights. For this situation, reduce the
maximum torque of the wrench. Before starting
work, ask your alkitronic® Partner or Alki Technik
GmbH for safe solutions.
If the tool tends to“ride up” or“creep”, stop and re-
adjust the reaction area to a more solid and secure
position.

3.2 Using and positioning the alkitronic® / Norwolf
reaction torque arm (DMA)
Depending on the application, a DMA can also be
used optional.
Professional positioning of the alkitronic®/ Norwolf
DMA is dependent on the joint. For individual
solutions your alkitronic® Partner or alki TECHNIK
GmbH will gladly advise you.

5. Function Test, Maintenance and Storage
Case and accessories, such as the reaction torque arm (DMA),
must be regularly inspected for damage and must be replaced
professionally if necessary.
In case of unusual mechanical noises, a lubrication of the rachet
drive lever is urgently recommended to prevent subsequent
damage.
Maintenance
The alkitronic®M-ML/Norwolf Missing Link / Z series / XCE
Link torque multiplier is an extremely powerful and robust
product.
Tighten all cap screws after every major use to ensure
they have not unseated. Clean the outside of your
alkitronic® / Norwolf tool, removing all grit and oil
after every use.
To ensure a long life and reliability over many years the tool
must be serviced in regular intervals (performance check,
safety inspection).
The torque multiplier must be inspected at least
once a year.
After high stresses / loads or lengthy hours of op-
eration calibration and servicing must be carried out
more frequently.
Please contact your alkitronic®partner.
Storage
Thealkitronic ®/ Norwolf manualtorquemultiplier
should be stored dry, cooled down and dust-free
in its original packaging or in another lockable
container. Warmth and humidity may lead to
oxidations in parts within the tool housing.
Following these rules will reduce the risk of
malfunctions.
For repairs the alkitronic® / Norwolf manual torque multiplier
must be sent to the appropriate alkitronic® Partner or directly
to alki Technik GmbH in its original package.
