Operating Area

Tightening Time

The tightening time is depending on joint hardness. Hard joints give short operation time, and soft joints give longer operation time.

Max. recommended tightening time is 3 seconds. Longer time indicates that the joint is too soft for the machine used. If so it is recommended to choose a bigger size of machine or another type of nutrunner.

Pulses per Tightening

An increased number of pulses per tightening implies improved accuracy. Fewer pulses per tightening implies an increased scatter.

Min. recommended number of pulses per tightening is 3. Few pulses per tightening at a low setting indicates that the free speed ought to be reduced by the trim valve.
