Wear a hard hat, protective glasses, and other protective equipment, as required.
When work is performed around an engine system that is operating, wear protective devices for ears to help prevent damage to hearing.
Do not wear loose clothing or jewelry that can snag on controls or on other parts of the engine system.
Ensure that all protective guards and all covers are secured in place on the engine system.
Never put maintenance fluids into glass containers. Glass containers can break.
Use all cleaning solutions with care.
Report all necessary repairs.Unless other instructions are provided, perform the maintenance under the following conditions:
The engine system is stopped. Ensure that the engine system cannot be started.
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 to help prevent sparks.
When starting a new engine system, make provisions to stop the engine system if an overspeed occurs. If an engine system has not been started since service has been performed, make provisions to stop the engine system if an overspeed occurs. Shutting down the engine system may be accomplished by shutting off the fuel supply and/or the air supply to the engine system.
Do not attempt any repairs that are not understood. Use the proper tools. Replace any equipment that is damaged or repair the equipment.
Start the engine system with the operator controls. Never short across the starting motor terminals or the batteries. This method of starting the engine system could bypass the engine system neutral start system and/or the electrical system could be damaged.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).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.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.Fluid Penetration
Illustration 3 g00687600Always 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.Containing Fluid Spillage
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with
