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.

Service instruction and/or have been trained for service on Tensor STR Tools.
