Information
- The tightening steps in the tightening sequences relate to tightening screws uniformly, i.e. all affected screws must first be tightened uniformly to the first torque value, then all screws are tightened one stage further, and so on.
- Replace all O-rings following removal!
Information
The following screws must be replaced after disassembly and/or after loosening:
- Aluminum screws
- Screws tightened to angle of rotation.
- Screws tightened using the yield-point-controlled method.
- Screws that are micro-self-locking
- Screws that are damaged or severely corroded.
The torques specified in the table below generally apply to screws that are not specifically listed =>
The bolt quality is indicated on the screw head at the top as a decimal number, e.g. "8.8" or "12.9".
