Direction of impacting water or steam jet (from inside to outside).
1. Seal off the air intakes of the engine and compressor air filters before starting cleaning.
2. Clean the cooling fins with compressed air, water or steam jet in the opposite direction to the
cooling air flow (from inside to outside).
3. Remove the protective coverings from the air filters.
4. Turn on the «battery isolating switch».
5. Close the doors.
6. Start the machine and run up to operating temperature so that excess water is evaporated.
Clean the cooler fins only in a washing area equipped with an oil separator!

─ General guideline values for tightening torques.
─ Specific guideline values for tightening torques.
■ Sealed screw connections.
➤ Follow all instructions carefully.
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.

Damage to the machine from insufficient clamping force at screw connections
➤ Tighten all screw connections with the defined tightening torque.
2. Determine the thread size for the screw connection.
