3. For determining the defined torque, see chapter 2.4.2.
4. Tighten all screw connections with the defined torque.
Specific guideline values for tightening torques:
Screw connections for components that are either safety-related or under particular stress must be
tightened with specific tightening torques.
Examples:
■ For details of specific tightening torques, see chapter 2.4.2.
─ E.g. Screw connections on lifting eyes.
■ Values for further specific tightening torques are provided in the section covering the relevant
maintenance task.
1.
Damage to the machine from insufficient clamping force at screw connections
➤ Screw connections for components that are either safety-related or under particular stress
must be tightened exclusively with the correct specific tightening torque.
2. Determine the correct specific tightening torque.
3. Tighten the screw connections with the specific tightening torque.
Sealed screw connections:
Screw connections which must not be adjusted are sealed with a coloured locking varnish.
1.
Damage to the machine caused by adjusting the settings
➤ Leave sealed screw connections in their original condition.
2. Do not loosen or adjust sealed screw connections.
Failure to comply with these instructions will invalidate all warranty claims.
10.9 Check wing doors
The closed wing doors perform the following functions when the machine is running: Protec‐
tion against contact, cooling air flow, sound proofing and weather protection.
To ensure these functions at all times, the doors and their connecting elements must always
be in perfect working condition.
Material Acid-free oil
Precondition The machine is switched off.
The machine is fully vented, the pressure gauge reads 0 psig.
The machine has cooled down.
All compressed air consumers are disconnected, the discharge valves are open.
Check function of wing doors:
1. Close all wing doors.
2. Close all catches.
