Description
Version:
Torque wrench without scale. Wrench setting using torque analyser. The trigger mechanism makes unintentional overtightening extremely unlikely. Anti-clockwise tightening by reversing the plug-in head.
Function:
On reaching the preset torque value the wrench triggers a clearly detectable deflection and is then immediately ready for use again. The long-travel indication gives the user an unmistakable signal that the set torque has been reached.
Application:
For controlled tightening of screws to a pre-set torque during batch productions.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
±4 % of the set value.
Cutting data:
Legend for drawing and formula:
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
Note:
Suitable spare jaws No. 657582 - 657950.
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
Warning:
Intended use
Reasonably foreseeable misuse
- Before use, check that the trigger value is set correctly and that the tool is securely seated.
- Position the tool so that it cannot slip off the screw connection.
- Avoid universal joints or extensions to prevent transmission errors.
- Handle the torque wrench carefully and protect it from mechanical, chemical and thermal influences.
- Ensure that the tools used have a standards-compliant design and the appropriate shape and size.
- For both industrial and private use.
- Use only when it is technically in good condition and safe to operate.
- Have the wrench regularly calibrated and adjusted.
Reasonably foreseeable misuse
- Never exceed the maximum value of the torque wrench (e.
- g.
- when loosening seized screws).
- Do not use the torque wrench as a striking tool.
- Avoid extreme climatic conditions such as cold, heat or humidity as they may impair the triggering accuracy.
- Do not use self-made special tools as they may constitute a hazard.
- Use tools with a maximum load that is greater than the achievable trigger torque of the torque wrench.
