Description
Version:
With reversible ratchet and fixed square drive pin − only for right-hand tightening.
Function:
On reaching the set torque value the wrench triggers giving a ″signal″ (audible and perceptible) and is then immediately ready for use again.
Application:
For small to medium series.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
±3 % of the displayed 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:
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
- For controlled tightening of nuts and bolts.
- 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.
- Avoid vibration, reverse movement, shaking, impacts.
- Do not use the wrench as an impact tool, do not throw it.
- Do not use it for undoing screw fastenings.
- Not for use where there is exposure to intense heat, direct sunlight, naked flames or liquids.
- Do not make any unauthorised modifications.
Reasonably foreseeable misuse
