Overhaul

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Service must only be carried out by qualified personnel who have access to the Service instruction and/or have been trained for service on Tensor STB Tools.

The electric motor is a sealed unit and may under no circumstances be opened by anyone else than Atlas Copco Industrial Technique AB!

If it is judged that the electric motor is defect or in need of service, the complete motor unit should be returned to Atlas Copco Tools for exchange.

Motors which have been opened by anyone else than Atlas Copco Tools will not be serviced.

Overhaul and preventive maintenance is recommended at regular intervals once per year or after maximum 250.000 tightening depending on which occurs sooner. More frequent overhaul may be needed if the machine is used in heavy-duty operations. If the machine not is working properly, it should immediately be taken away for inspection.

When dismantling the tool always use the specially designed service tool 4080 0848 80, (two service tools are required).
