10.5.6 Inspect both coolers for leaks
1. Open the enclosure.
2. Turn the «Controller On» switch to the “0” position.
3. Visually inspect for leaks: Is cooling oil/coolant leaking out?
Is the oil cooler/coolant cooler leaking?
➤ Have the defective oil cooler/coolant cooler repaired or replaced immediately by
KAESER SERVICE.
4. Close the enclosure.
10.6 Checking the screw connections
Overview:
■ Guideline values for tightening torques.
─ General guideline values for tightening torques.
─ Specific guideline values for tightening torques.
■ Sealed screw connections.
➤ Follow all instructions carefully.
10.6.1 General guideline values for tightening torques
Guideline values for the required tightening torques are dependent upon the size of the screw con‐
nection, the strength class of the screw material and the friction coefficient.
NOTICE
Damage to the machine from insufficient clamping force at screw connections
➤ Tighten all screw connections with the defined tightening torque.
1. Determine the thread size for the screw connection.
2. For determining the defined torque, see chapter 2.4.2.
3. Tighten all screw connections with the defined torque.
10.6.2 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.
─ E.g. Cover screws on the oil separator tank.
■ Values for further specific tightening torques are provided in the section covering the relevant
maintenance task.
