Troubleshooting

If the nutrunner does not start:

Power Focus 600/6000

Is the unit switched on? Check the earth fault circuit breaker behind the front

door. Should it have tripped, make sure to find the primary fault before resum-

ing operation. Check that the wiring on the remote start connector is correct.

For further information see 9836 4954/9836 7446.

Power Focus 3000/4000

Is the POWER FOCUS switched on and in RUN mode? Check that the correct

POWER FOCUS is used (ST31/ST32/ST61/STR31/STR61-Tensor3-7, ST81-

Tensor8-9). Check the fuses for the drive part. Check Drive parameters, refer to

the User Guide of the POWER FOCUS/ drive unit. Check the earth fault circuit

breaker on the backside of the drive. Should it have tripped, make sure to find

the primary fault before resuming operation. Check that the wiring on the re-

mote start connector is correct. For further information see 9836 2258.

If the tool becomes very hot

With proper adjustment the tool can handle any normal line jobs that an opera-

tor sustains. What can cause overheating are combinations of some factors:

torque above rated, too low speed, too long ramp time (motor has to give high

torque for a long time), very high prevailing torque, very soft joints, short cycle

time. To correct, look over speed, ramp time, tightening strategy. One stage and

Ergoramp are most heat conserving when applicable. Please refer to the User

Guide of your POWER FOCUS. If the above corrections are not enough,

choose a tool of the next higher capacity.
