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 and long tightening times. If the machine is not working properly, it should immediately
be taken away for inspection.
The strainer at the air inlet and the exhaust silencer should be cleaned frequently or replaced in order to
prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accurately and defective or worn parts (i.e. O-rings, vanes)
should be replaced.
