Test equipment and performance

Equipment:

• Tachometer.

• STanalyser.

• SRTT transducer (secure the transducer firmly).

1. Test the free speed in the forward direction with the tachometer.

   For AutoTrim versions make sure that the unreduced speed is measured (refer to section Function control - AutoTrim in the Trouble shooting schedule chapter of the service instruction for details).

   Test the AutoTrim function.

2. Test the max torque and pulse frequency.

   Set the filter frequency in STanalyser to 850 Hz.

   Measure the torque and pulse frequency in the reverse direction. Use a tightening time of approximately 1 second.

3. Check of shut-off mechanism.

   Run the tool in the forward direction. If the shut-off mechanism is working properly the tool shuts off.
