Service instructions

Overhaul and preventive maintenance is recommended at regular intervals once per year or after a maximum of 250.000 tightenings. More frequent overhaul may be needed if the tool is used at high torque or with long tightening times. Take out the tool for inspection if it is not working correctly.

At overhaul, clean all parts accurately and replace defective or worn parts.

Lubricate gears and clutch with grease containing molybdenum disulphide, for example Molykote BR2 Plus, refer to the exploded views.

Lubricate o-rings and threaded connections with grease before assembling.

Make sure that all threaded connections on the tool are tightened correctly according to the specifications on the exploded views.
