Preventing ESD problems
The components inside the tool and controller are sensitive to electrostatic dis-
charge. To avoid future malfunction, make sure that service and maintenance is
carried out in an ESD approved work environment. The figure below shows an
example of an appropriate service work station.
Service recommendations
Overhaul and preventive maintenance is recommended at regular intervals. If
the machine is not working properly, it should immediately be taken away for
inspection. At the overhauls, all parts should be cleaned accurately and defec-
tive or worn parts should be replaced.
Overhaul
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 STR 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.
