1. Hold the output drive firmly.
2. Carefully push the hex wrench (WAF 2)
through the hole of the pistol grip housing until
it reaches the torque adjustment screw
.
3. Turn the torque adjustment screw and roughly
set the required torque, see Abb. 4-1 ,
page 116.
Total number of turns = 6.
4. Remove hex wrench.
The hole will automatically close after starting.
5. Carry out the rundown.
6. Check the shutoff mechanism worked
properly, see 4.4.3 Measuring the torque,
page 13.
7. In case of deviations, correct the torque setting
and
8. Repeat the rundown.
Requirement
Measure
High shut-off accuracy –
especially with hard screwed joints.
Increase number of pulses per tighten-
ing.
Recommended number of pulses
6.
Reduce the speed.
1. Unscrew the threaded pin using the
hex wrench (WAF 2).
2. Turn exhaust air throttle
clock-
wise.
Shortening the rundown time, particu-
larly for soft joints.
Increase the speed.
1. Unscrew the threaded pin using the
hex wrench (WAF 2).
2. Turn exhaust air throttle
anti-
clockwise.
NOTE
