Select the Link Tool corresponding to the joint.
• Place the alkitronic® M-ML/Norwolf Missing Link / Z series
completely on the nut.
• Position the housing (optional with DMA) against the
reaction point until contact is made.
• Determine whether you have a 4:1 or a 6:1 ratio of your
alkitronic®/Norwolf tool.
• Set the desired torque according to the operation manual
of your Torque Wrench
• Check the rotation direction switch (1) on the torque
wrench to ensure correct rotation (cw = R, ccw = L,
neutral position = O).

The rotation direction (1) of the Torque Wrench
must be in agreement with the engraved arrow
"TURN" (2) on the Missing Link / Z series.
• Position the Torque Wrench on the drive and apply contin-
uous force until the application is tightened satisfactorily.
Make certain the final torque is transmitted to the
bolt connection. The tool does not stop until its
Rachet Drive Lever reaches the final position.
You cannot turn the nut any further: Retain the
tension on the Torque Wrench. Switch the return
twist lock on the Torque Wrench to neutral position
without using force. The Rachet Drive Lever will
retract automatically. While retracting, you will hear 1-3
"clicks" indicating that the tool has reset itself. Repeat this
procedure once or twice and if no audible clicks are heard on
retraction, at this point, the pre-set torque is achieved with
an accuracy of ± 8%.
Repositioning the Missing Link / Z series on the next bolt joint.
Loosening
The rotation is changed by reversing the Missing Link
by 180
. Insert the Torque Wrench. To loosen the bolt

connection, the direction of rotation must match
the engraved arrow "TURN" on the Missing Link.

Select the alkitronic® / Norwolf XCE Link corresponding to
the joint.
• Place the XCE Link completely on the nut.
• Position the housing (optional with DMA) against the
reaction point until contact is made.
• Determine whether you have a 3:1 or 4:1 ratio of your
alkitronic® / Norwolf XCE Link.
• Set the desired torque according to the operation manual
of your electric or pneumatic driven Torque Multiplier.
The rotation direction of the Torque Multiplier must
be in agreement with the engraved arrow "TURN"
(Fig. 11/ 2) on the XCE Link.

• Insert the Torque Multiplier into the splined hub (3).
Energy supply depends on the type of drive. Turn on
machine.
• Keep pressing the start button of the electric or pneumatic
multiplier until the drive stops turning and pre-set pres-
sure is reached.
