Page 8 ENAssembly instructions 2. Lubricants2.1 General information
All products from SKF Lubrication Systems may be used only for their intended purpose and in accordance with the information in the product's assembly instructions.Intended use is the use of the products for the purpose of providing centralized lubrication/lubrication of bearings and friction points us-ing lubricants within the physical usage limits which can be found in the documentation for the devices, e.g., assembly instructions/operat-ing instructions and the product descriptions, e.g., technical drawings and catalogs. Particular attention is called to the fact that hazardous materials of any kind, especially those materials classi ed as hazardous by EC Directive 67/548/EEC, Article 2, Para. 2, may only be  lled into SKF centralized lubrication systems and components and delivered and/or distributed after consultation with and written approval from SKF Lubrication Systems . No products manufactured by SKF Lubrication Systems are approved for use in conjunc-tion with gases, lique ed gases, pressurized gases in solution, vapors, or such  uids whose vapor pressure exceeds normal atmospheric pressure (1013 mbar) by more than 0.5 bar at their maximum permissible temperature. Other media which are neither lubricants nor hazardous substances may only be fed after consultation with and written approval from SKF Lubrication Systems.SKF Lubrication Systems considers lubricants to be a component of the system design which must be factored into the selection of compo-nents and the design of centralized lubrica-tion systems. The lubricating properties of the lubricants are critically important in these considerations.2.2 Selection of lubricants
Observe the instructions from the machine manufacturer regarding the lubricants that are to be used.Warning!The amount of lubricant required at a lubrication point is speci ed by the bearing or machine manufacturer. It must be ensured that the required quantity of lubricant is provided to the lubrication point. The lubrication point may otherwise not receive adequate lubrication, which can lead to damage and failure of the bearing.The selection of a lubricant suitable for the lubrication task is made by the machine/system manufacturer and/or the operator of the machine/system in cooperation with the lubricant supplier. The bearings/friction points that require lubri-cation, their expected load during operation, and the expected ambient conditions are taken into account during selection, with consider-ation of economic and environmental aspects.

Page 9 ENAssembly instructions 2.4 Lubricants and the environmentLubricants can contaminate soil and bodies of water. Lubricants must be properly used and disposed of. Observe the local regulations and laws regarding the disposal of lubricants.It is important to note that lubricants are environmentally hazardous,  ammable substances that require special precaution-ary measures during transport, storage, and processing. Consult the safety data sheet from the lubricant manufacturer. For information regarding transport, storage, processing, and environmental hazards of the lubricant that will be used. The safety data sheet for a lubricant can be requested from the lubricant manufacturer. Where necessary, SKF Lubrication Systems supports customers in the selection of suitable components for feeding the selected lubricant and in the planning and design of a central-ized lubrication system.Please contact SKF Lubrication Systems if you have further questions regarding lubricants. Lubricants can be tested for their feedability (e.g. "bleeding") and use in central lubrication systems in an on-site laboratory.You can request an overview of the lubricant tests offered by SKF Lubrication Systems from the company's service department.2.3 Approved lubricants
Only lubricants approved for the prod-uct may be used. Unsuitable lubricants can lead to failure of the product and damage to property. Different lubricants must not be mixed, as mixing may result in damage and necessitate costly and complicated cleaning of the product/lubrication system. It is recommended that an indication of the lubricant in use be attached to the lubricant reservoir in order to prevent accidental mixing of lubricants.The product described here can be operated using lubricants that meet the speci cations in the technical data. Depending on the product design, these lubricants may be oils,  uid greases, or greases.Oils and base oils may be mineral, synthetic, and/or rapidly biodegradable. Consistency agents and additives may be added depending on the operating conditions.Note that in rare cases there may be lubri-cants whose properties are within permissible limit values but whose other characteristics render them unsuitable for use in centralized lubrication systems. For example, synthetic lu-bricants may be incompatible with elastomers.

Page 10 ENAssembly instructions 2.5 Lubricant hazards Centralized lubrication systems must always be free of leaks. Leaking lubricant is hazardous due to the risk of slipping and injury. Beware of any lubricant leaking out during assembly, operation, maintenance, and repair of centralized lubrication systems. Leaks must be sealed without delay.Lubricant leaking from centralized lubrication systems is a serious hazard. Leaking lubricant can create risks that may result in physical harm to persons or damage to other material assets.Follow the safety instructions on the lubricant's safety data sheet.Lubricants are a hazardous substance. The safety instructions on the lubri-cant's safety data sheet must be strictly followed. The safety data sheet for a lubricant can be requested from the lubricant manufacturer.
