1 27 STAHLWILLE Standard Manoskop 721 Service Manoskop 730 Technical descriptionAll modelsManoskop 721, 730 are adjustable torque wrenches with a cut-out, tactile and audible cut-out signals. These torque wrenches have a safety cut-out mechanism. The wrench is set to cut-out at a certain torque level by setting the required value on the force-free sliding scale. The setting slide has an automatic setting fail-safe mechanism. The measuring element is a flexible rod. The flexible rod is not pretensioned so it is only under tension from the start to the end of the actual tightening operation until the wrench cuts of contentsTechnical description.

These wrenches will only tighten in one direction. To use the wrench for loosening, turn it over. Exception: The Manoskop 721/5 and 721/15 cannot be used for counter clockwise tightening. If necessary, these torque wrenches can be readjusted without permissible deviation of the set value from the absolute value at cut-out is 4%. Manoskop 721 and 730 comply with DIN EN ISO 6789, Type II, Class Manoskop has a unique serial number and is supplied with a works calibration 721/5 and 721/15.

Controlled counter clockwise tightening is not Manoskop 721/30 .. has a permanent, switchable ratchet with a push-through (1/2") square drive. 29 Service Manoskop 730/2 to 730/65 .. can be fitted with various insert tools. For this purpose, the head of the wrench has a recessed square drive at the face (sizes are shown in the Technical Specifications) with a double-sided locating hole and insertion groove. The insert tools can be attached in the normal position or rotated through 180.

5 In order to loosen a nut or bolt during the normal tightening process, the Manoskop can also be used in the opposite direction. Manoskop 721 and 730 may only be used for these purposes. To do so, the correct attachments must be used with the torque intended purpose includes full adherence to the information contained in this instruction booklet, in particular the safety instructions and technical tolerance limits. The buyer is required to ensure that all users comply with these use beyond the use described here is in breach of the intended buyer and user are responsible for any damage or injury resulting from non-adherence to these instructions.

6 Manoskop 721 and 730 have not been designed for tightening of screw joints under series production conditions. This might lead to inaccurate readings as a result of inadvertent operation of the sliding scale. The Manoskop may not be used as a hammer. This will lead to injury and damage. Important safety points31 The Manoskop may not be used for uncontrolled loosening of nuts & bolts for example rusty joints. This may cause damage to the torque torque settings .. can be lifesaving in some applications. For this reason, please note the following points:Unless internal regulations at the place of use say otherwise ( test equipment inspection to ISO 9000 et seq.)

7 Inspection should take place after approx. 5000 uses or every 12 months, whichever is the shorter. If an inspection shows that there is excessive deviation, the torque wrench will have to be readjusted (see page 44). Additional important safety points .. may apply depending on the application. These are found in the appropriate sections marked with danger symbols . C A U T I O N !In order to ensure the cut-out is working accurately, it should be checked at regular intervals. 32 OperationManoskop 721 and 730 are measuring instruments and must be treated with utmost care. Avoid subjecting the tool to physical knocks, chemicals or excessive temperatures beyond the limits given in these note that extremes of climate (cold, heat, humidity) may affect measuring overloading the tool by more than 30% of the maximum permissible load in the direction of tightening or in the opposite direction.

8 The Manoskop may be damaged. After such an overload, the readings may be inaccurate in such a way that the user does not the inserts and insert toolsThese guarantee the correct lever length, fit accurately in all situations and are designed to have sufficient strength. C A U T I O N !When using inserts on torque wrenches with a square drive, ensure they have been manufactured to comply with standards and are the correct shape and size for the nut or bolt to be tightened. STAHLWILLE inserts guarantee the connection will be a good fit and that the drive profile will fit exactly. C A U T I O N !Please use only insert tools made by STAHLWILLE .

9 C A U T I O N !Ensure the maximum permissible load of the insert or tool used is not exceeded. This might be lower than the maximum cut-out torque of the torque that the tool has to be of the correct type and the right size for the screw or insert tools721/5 and 721/151. For controlled clockwise tightening, switch the ratchet to R or, for uncontrolled loosening of joints, to L . C A U T I O N !Use of home-made special tools may be dangerous. If you need to manufacture your own tools, please contact STAHLWILLE first. D A N G E R !When using insert tools, ensure that the locking pin has located correctly.

10 Otherwise, there is a danger of injury or Slide the insert over the square drive of the ratchet until it Check that the square drive is fitted to the right side of the torque If not, push the square drive out through the upper side to the right For controlled tightening, switch the ratchet to R or, for uncontrolled loosening of joints, to L .4. Slide the insert over the square drive until it insert tools - 730/2 to 730/651. Insert the insert tool into the internal square drive on the face of the head of the wrench . The spring-loaded locking pin of the insert tool will be pressed down by the insertion groove.
