6.2 Torque values

All screws and nuts must be lubricated to achieve correct tightening torque. Screws that
are screwed into stainless steel must have the threads coated with suitable lubricants to
prevent seizing.
If there is a question regarding the tightening torques, then contact a sales or authorized
service representative.
