Measure
► Make sure that the operator keeps the start trig-
ger pressed throughout the entire sequence.
► Increase the fastening time.
► Check the fastening sequence to ensure that the
torque shutoff value and/or angle setpoint are
correct. Adjust as necessary.
► Check whether the fastening joint has changed
significantly.
► Make sure that the speed in the stages is correct.
► Parameterize the work light: In the CellClutch
PC software, select Bright or Dim for Work Light.
► Parameterize the status light: In the CellClutch
PC software, select Bright or Dim for Status Light.
► Use a fully charged battery.
► Use a fully charged battery.
If a high torque is needed for a longer period, e.g. for
several turns, the number of rundowns that can be
achieved with one battery charge will be significantly
reduces.
After 800 charging cycles, the capacity is reduced to
approx. 60%.
► Use new battery.
► Press start switch. If the status light continues to
flash, send the tool to a Sales & Service Center
for repair.
