Preventive maintenance

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.

The tightening torques indicated in the exploded views list in ServAid (see Spare parts section in

servaid.atlascopco.com) are established to achieve the correct clamping force and prevent the parts from

coming loose.

When servicing these parts, they must be able to open up without being destroyed. In special circum-

stances (depending on application and usage) the parts may however come loose after some time of op-

eration. In such cases the torque can be increased by 10-20%. If necessary, a low or medium threadlock-

ing fluid can also be applied.

Example

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.

Cleaning

Clean all parts thoroughly in white spirit or similar cleaning agent. To prevent clogging and decreased

power, it could be necessary to clean the strainer (if used) and the exhaust filter between the overhauls.
