8 SEBU8598 Safety Section General Hazard Information The engine is stopped. Ensure that the engine cannot be started. Fluid Penetration The protective locks or the controls are in the applied position. Disconnect the batteries when maintenance is performed or when the electrical system is serviced. Disconnect the battery ground leads. Tape the leads in order to help prevent sparks. When starting a new engine, make provisions to stop the engine if an overspeed occurs. If an engine has not been started since service has been performed, make provisions to stop the engine if an overspeed occurs.
Shutting down the engine may be accomplished by shutting off the fuel supply and/or the air supply to the engine. Illustration 6 g00687600 Do not attempt any repairs that are not understood. Use the proper tools. Replace any equipment that is damaged or repair the equipment. Always use a board or cardboard when you check for a leak. Leaking fluid that is under pressure can penetrate body tissue. Fluid penetration can cause serious injury and possible death. A pin hole leak can cause severe injury. If fluid is injected into your skin, you must get treatment immediately. Seek treatment from a doctor that is familiar with this type of injury. Start the engine with the operator controls.
Never short across the starting motor terminals or the batteries. This method of starting the engine could bypass the engine neutral start system and/or the electrical system could be damaged. Containing Fluid Spillage NOTICE Care must be taken to ensure that fluids are con- tained during performance of inspection, mainte- nance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable contain- ers before opening any compartment or disassem- bling any component containing fluids. Pressurized Air and Water Pressurized air and/or water can cause debris and/or hot water to be blown out which could result in personal injury.
The maximum air pressure for cleaning purposes must be reduced to 205 kPa (30 psi) when the air nozzle is deadheaded and used with effective chip guarding (if applicable) and personal protective equipment. The maximum water pressure for cleaning purposes must be below 275 kPa (40 psi). Refer to Special Publication, NENG2500, “Cat Dealer Service Tool Catalog” or refer to Special Publication, PECJ0003, “Cat Shop Supplies and Tools Catalog” for tools and supplies suitable to collect and contain fluids on Cat products. When pressurized air and/or pressurized water is used for cleaning, wear protective clothing, protective shoes, and eye protection.
Eye protection includes goggles or a protective face shield. Always wear eye protection for cleaning the cooling system. Dispose of all fluids according to local regulations and mandates. Avoid direct spraying of water on electrical connectors, connections, and components. When using air for cleaning, allow the machine to cool to reduce the possibility of fine debris igniting when redeposited on hot surfaces.
