Maintenance
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 instructions
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 used at high torque, high cy-
cle rate or long tightening times. 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 defective or worn
parts (i.e. O-rings) should be replaced.
Cleaning/Inspection
Clean all parts thoroughly in white spirit or similar cleaning agent. After the
cleaning, inspect all parts. Damaged and worn parts should be replaced.
Lubrication
