3 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. 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.

4 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.) 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.

5 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 . 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.

6 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. 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. Slide the insert tool in until it comes to the endstop. Ensure the locking pin locates in the Check to see that the insert tool is properly To tighten counter clockwise, turn the insert tool through 180 before attaching to the torque If you are using a ratchet insert tool, set this to the desired direction by turning the control insert tools730/2 and 730/41.

7 Insert a fine punch into the locating hole of the shell tool from outside. Use the punch to depress the locking Remove the insert to 730/651. If the tool was attached in the normal position, press the release button on the underside of the head of the wrench. If the tool was attached to the torque wrench rotated through 180 . Insert a fine punch into the locating hole in the head of the wrench. Use the punch to depress the locking Extract the insert the torque levelThe torque level at which the wrench cuts out is set by moving the scale against the fixed mark. Always approach the desired torque setting from a lower value. Intermediate settings between two marks on the scale can be order to be able to set the scale, the setting fail-safe mechanism has to be operated first. Once the setting fail-safe mechanism is released, the value set is automatically as follows:1. Depress the button on the underside of the tool, or the pressure plate in the end of the handle as appropriate, to release the setting fail-safe Slide the scale to a torque level lower than the desired cut-out Now slide the scale to the desired cut-out Release the button / pressure plate.

8 The torque level is now Check the value again. If the setting is wrong, return to counter clockwise tighteningFor reasons of accuracy, these torque wrenches have been designed to work in only one direction. The direction is marked with an counter clockwise tightening is possible by turning the Manoskop over. Exceptions: The Manoskop 721/5 and 721/15 cannot be used for counter clockwise controlled counter clockwise tightening using the Manoskop 721/30 in the turned over position, the square drive must first be pushed through to the upper controlled counter clockwise tightening using the Manoskop 730/2 to 730/65, the insert tool has to be rotated through 180 . Ratchet insert tools also need switching to L (CCW) for the correct tightening loosening of nuts & bolts .. opposite to the tightening direction is possible. The cut-out mechanism is not placed under load during this the torque wrench C A U T I O N !Important! Never exceed a limit of 130% of the maximum scale reading.

9 Do not use the tool for loosening rusty nuts and bolts. This may cause damage to the torque wrench. After such an overload, the readings may be inaccurate in such a way that the user does not notice. D A N G E R !Before you use the wrench, check that the cut-out value is set to the correct level and that the insert tool is firmly in place. Apply the tool in such a way that it cannot slip off the nut or bolt. Otherwise, there is a danger of injury or apply force to the Manoskop via its handle. Hold the handle in the middle. Apply force at a tangent to the swivel radius and at right angles to the axis of the nut or steadily and without any interruption, particularly during the final phase, until you feel a jerk and hear a click. The torque level set on the scale has now been soon as the torque wrench has cut out, it is ready for the next job C A U T I 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 internal mechanisms of the torque wrench are subject to normal wear and tear under operating conditions.

10 For this reason, the accuracy of the cut-out should be checked at regular intervals. Unless internal regulations at the place of use say otherwise ( test equipment inspection to ISO 9000 et seq.) inspection should take place after approx. 5000 uses or every 12 months, whichever is the inspection shows that there is a deviation, the torque wrench must be inspection and adjustment must be carried out in accordance with DIN EN ISO the accuracy of the cut-out valueA torque tester is necessary for the inspection with sufficient capacity for the wrench to be tested and with a guaranteed accuracy of 1% of the displayed you have access to such a tester, you may inspect the Manoskop yourself. Suitable torque testers are available from STAHLWILLE . It is also possible for STAHLWILLE to test the Manoskop for carry out the test, proceed as follows:1. Set the torque wrench to the highest scale reading2. Operate the torque wrench five times ensuring it cuts out properly each time433.
