Wear a hard hat, protective glasses, and other protective equipment, as required.
When work is performed around an engine that is operating, wear protective devices for ears in order 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.
Ensure that all protective guards and all covers are secured in place on the engine.
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 is stopped. Ensure that the engine 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 in order to help prevent sparks.
When starting a new engine or an engine which 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.
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 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.Electrostatic Phenomena
The operator, the installer, and other personnel should be aware of excessive polishing or buffing of plastic parts which could result in an energy potential that could cause a spark that could possibly ignite an explosive atmosphere.This petroleum engine may be for use as a component in ATEX Directive (94/9/EC) Group II, 3G environments with Gas Group IIA, Temperature Class T3 (200 Deg. C maximum surface temperature). The OEM must ensure that non static belts are used. Failure to use non static belts could result in an energy potential that could cause a spark that could possibly ignite an explosive atmosphere.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.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. 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). Always wear eye protection for cleaning the cooling system.Fluid Penetration
Illustration 3 g00687600
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.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 suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Caterpillar Shop Supplies and Tools Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Lines, Tubes, and Hoses
Do not bend or strike high-pressure lines. Do not install lines, tubes, or hoses that are damaged.Repair any fuel lines, oil lines, tubes, or hoses that are loose or damaged. Leaks can cause fires.Inspect all lines, tubes, and hoses carefully. Do not use bare hands to check for leaks. Always use a board or cardboard for checking engine components for leaks. Tighten all connections to the recommended torque.Check for the following conditions:
End fittings that are damaged or leaking
Outer covering that is chafed or cut
Wire that is exposed in reinforced hose
Outer covering that is ballooning locally
Flexible part of the hose that is kinked or crushed
Armoring that is embedded in the outer coveringEnsure that all of the clamps, the guards, and the heat shields are installed correctly. Correct installation of these components will help to prevent these effects: vibration, rubbing against other parts and excessive heat during operation.Inhalation

Exhaust
Use caution. Exhaust fumes can be hazardous to your health. If you operate the equipment in an enclosed area, adequate ventilation is necessary.Asbestos Information
Caterpillar equipment and replacement parts that are shipped from Caterpillar are asbestos free. Caterpillar recommends the use of only genuine Cat replacement parts. Use the following guidelines when you handle any replacement parts that contain asbestos or when you handle asbestos debris.Use caution. Avoid inhaling dust that might be generated when you handle components that contain asbestos fibers. Inhaling this dust can be hazardous to your health. The components that may contain asbestos fibers are brake pads, brake bands, lining material, clutch plates, and some gaskets. The asbestos that is used in these components is usually bound in a resin or sealed in some way. Normal handling is not hazardous unless airborne dust that contains asbestos is generated.If dust that may contain asbestos is present, there are several guidelines that should be followed:
Never use compressed air for cleaning.
Avoid brushing materials that contain asbestos.
Avoid grinding materials that contain asbestos.
Use a wet method in order to clean up asbestos materials.
A vacuum cleaner that is equipped with a high efficiency particulate air filter (HEPA) can also be used.
Use exhaust ventilation on permanent machining jobs.
Wear an approved respirator if there is no other way to control the dust.
Comply with applicable rules and regulations for the work place. In the United States, use Occupational Safety and Health Administration (OSHA) requirements. These OSHA requirements can be found in "29
