Preventing ESD problems
The components inside the tool and controller are sensitive to electrostatic discharge. To avoid future mal-
function, 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
Preventive maintenance is recommended at regular intervals. See the detailed information on preventive
maintenance. If the product is not working properly, take it out of service and inspect it.
If no detailed information about preventive maintenance is included, follow these general guidelines:
■
Clean appropriate parts accurately
■
Replace any defective or worn parts
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once per year or after maxi-
mum 250.000 tightening depending on which occurs sooner. More frequent overhaul may be needed if
used at high torque, high cycle 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.
