Technical description
The Manoskop
torque wrench with cut-out function,
audible and tactile cut-out signals.
•
The torque wrench has a safety cut-
out mechanism.
•
The cut-out level can be very quickly
and precisely set with little physical
effort by means of a setting knob.
•
The required value is secured by
means of a fail-safe mechanism on
the control knob.
•
The measuring element is a flexible
rod. The rod is not pre-tensioned and
therefore only under tension from
start to finish of the actual tightening
operation. After use it is not
necessary to reset to the lowest
value.
•
As soon as the torque wrench is
released, it is ready for the next job.
•
The ergonomically-shaped two-
component handle allows for
comfortable and safe operation. The
correct grip is indicated optically and
tactually.

    Correct torque settings ..can be lifesaving in some applications. For this reason, please note the following points: ã C AUTI O N ! In order to ensure the cut-out is working accurately, it should be checked at regular intervals.
  • Page 6 STAHLWILLE inserts guarantee the connection will be a good fit and that the drive profile will fit exactly.
  • Page 7 The calculation for correcting the set values and the extension adjustment size can be found in the STAHLWILLE catalogue. ã C AUTI O N ! Ensure the maximum permissible load of the insert or tool used is not exceeded.
  • Page 8 C AUTI O N ! Use of home-made special tools may be dangerous. If you need to manufacture your own tools, please contact STAHLWILLE first. ã D ANG ER ! When using insert tools, ensure that the locking pin has located correctly.

  • Page 10 5. If you are using a ratchet insert tool, set this to the desired direction by turning the control knob. Removing insert tools 1. If the tool was attached in the "normal" position, press the QuickRelease button on the underside of the wrench head (A). 2.
  • Page 11 Setting the torque level The range of measurement and units of measure can be found on the type plate and in the tables. For ease of differentiation they are shown in two colours. Torque levels indicated in the measurement area shown in black are set using the black main and fine scales.
  • Page 12 4. Turn the control knob and check the exact setting on the fine scale. ® Example: Manoskop 730N/10: For a desired setting of 62,5 N m, set the level to 2,5 N m. 5. Check the correct setting again. 6. When you have set the desired value, press the control knob back into the locking position.
  • Page 13 Setting torque levels using the green scale 1. Pull the control knob out of the locking position until it engages (A). 2. Turn the control knob (B) and check the green main scale. 3. Firstly set a value which lies under the desired setting.

    ã C AUTI O N ! Important! Once the wrench has cut out, never apply more pressure! You should therefore not pull too fast in case you cannot stop the motion quickly enough when you hear the click. As soon as the torque wrench has cut out, it is ready for the next job.

  • Page 20 The screw which is closest to the head is primarily for adjusting the upper end of the scale range. Each screw has a minor effect on the adjusting range of the other screw. To protect the mechanisms from dirt, these two holes are plugged. To adjust the wrench, you will need the torque tester and an Allen key, size 2 mm.
  • Page 21 Important! If you cannot compensate for the deviation within the prescribed tolerances using the method described here, it is likely that the cut-out mechanism is damaged. Such defects can only be repaired if the torque wrench is dismantled. Contact STAHLWILLE in such cases.
