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: 14 Nm
Screw M6: 10.9
Set speed to approximately 4800
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.

4.5 Troubleshooting
Error Possible causes Measures and remedies
Tool too strong Torque set too high Reduce the torque setting, see
4.4.2 Changing Torque, page 10
Tool too weak Working pressure too low Check the cross section of the
hose and coupling: Inner
diameter 3/8" (ø 9.5 mm), maxi-
mum length 5 m
Increase the working pressure.
Reverse button is
not at the detent Turn the reverse button
to the detent
Excessive transmission damping due
to extension and worn socket. Increase the speed, see 4.4.1 Set-
ting the torque, page 10.
Use a shorter or more rigid exten-
sion.
Replace the socket
Insufficient oil in the pulse unit (no
pulse build-up) See 5.2 Fill reserve oil, page 14
Screen in the air inlet tube /
muffler is dirty Clean or replace parts
Accuracy insufficient Adapter parts Replace adapter parts
Use extension and socket with
guide diameter
Pressure fluctuations in the air network Use a pressure regulator
Premature release of the start button Keep start button pressed until nut-
setter has stopped rotating
Fastening time too
long: > 4 seconds Joint too soft; crush nuts, self-tapping screws Increase the speed
Use a pulse nutsetter with a higher
capacity.

5.1.1 Calculating a customer-specific maintenance plan
A service interval W(1,2,3) depends on the following factors:
T2, Sand VS are variable factors and can differ depending on the specific application.
Example for service interval W2:
After 500,000 rundowns (V),
a specific rundown time of 1.8 seconds (T1)
with an actual fastening time of 3 seconds (soft joint) and
3 completed shifts per day and 750 rundowns per shift:
You have to carry out the maintenance measures marked W2 after an operating time of 200 days.
5.2 Fill reserve oil
If X = 0 (see picture 2), the reserve oil is exhausted and must be refilled to guarantee a controlled process.
