4.4.1
Setting the torque
Abb. 4-1
To achieve better repeat precision for fastenings, throttle the speed back at the tool until the required
torque is achieved at the end of rotation of the fastening. On hard to medium-hard screwed joints, this is
achieved in 1 to 2 seconds. Longer fastening then does not result in higher torque.
4.4.2
Changing Torque
Abb. 4-2
4.4.3
Checking torque
We recommend carrying out a
static
torque check by retightening the screwed joint.
If the torque difference is too large, it may be necessary to change the torque setting. See 4.4.2 Chang-
ing Torque.
If the setting has been changed, check the torque again.
When carrying out a
dynamic
measurement using a transducer adapter, also carry out a static test on the
screwed joint, for example with a torque wrench (electronic).
Settings example:
Tightening: 6 Nm
Screw M5: 8.8
Set speed to approximately 5000
rpm.
Unscrew the threaded pin using the hex
wrench (WAF 2).
To reduce torque,
turn the exhaust air throttle
clockwise.
To increase torque,
turn the exhaust air throttle
counter-clockwise.
NOTE
The torque setting may be corrected when the compressed air is activated.
