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

Overhaul

Service must only be carried out by qualified personnel who have access to the
