Cleaning and calibration of elements

To prevent dirt from getting inside assemblies and components, always remove any dirt build-up and grease deposits from them before disconnecting or dismantling any components.

Before inspecting the components prior to assembly or installation, they should be thoroughly cleaned.

Cleaning methods:

• dry cleaning
• removing dirt in accessible areas using soft or wire brushes
• scraping off dirt with a piece of metal or wood
• cleaning with a rag

CAUTION: Compressed air can sometimes be "wet". Therefore, use it with caution, especially when working on hydraulic systems.

• blowing out dirt with compressed air. (Eye protection must be worn when using this technique.).
• vacuum extraction. Dry dust removal using vacuum equipment. This technique should always be used to remove friction lining material dust (asbestos particles).
• steam cleaning

WARNING: Most solvents must be handled with care, some are hazardous. For safety information, refer to the "Health Protection and Precautions" chapter and the solvent manufacturers' instructions. Failure to follow these instructions may result in injury.

There are a number of solvents available which are suitable for component cleaning purposes. Some components, such as hydraulic brake components and electrical components, should only be cleaned using recommended solvents - refer to the Solvents, Sealants and Adhesives chapter or the section of the manual that applies to the specific component.

Calibration (taring) of important measuring equipment

WARNING: Failure to follow these instructions may result in injury or damage to components.

It is extremely important that certain mandatory equipment such as torque wrenches, multimeters, exhaust gas analyzers, roller stands, etc., are regularly calibrated in accordance with the manufacturer's instructions.
