13031 Mercury WASHER, LOWER

General Hazard Information
Attach a DO NOT OPERATE or similar warning tag to start switch or controls before servicing or repairing the truck engine. These tags, Form SEHS7332, are available from your Caterpillar dealer.Do not allow unauthorized personnel in the truck when maintenance or repair is being performed.* When operating the engine in a closed area, vent the exhaust to the outside.* If the engine is not running, do NOT release the secondary or parking brake system unless the truck is blocked or restrained.* Wear a hard hat, protective glasses and other protective equipment as required by job conditions.* Do not wear loose clothing or jewelry that can catch on controls or other parts of the engine.* Make certain all protective guards and covers are secured in place.* Use all cleaning solutions with care.* Never put maintenance fluids into glass containers since glass containers can break.* Report all needed repairs.* Stop the engine.* Ensure the protective locks or controls are in the applied position.* Apply the secondary (emergency) and parking brakes.* Block or restrain the vehicle before performing maintenance or repair.* Disconnect the batteries before performing maintenance on the electrical system.* Do NOT attempt repairs you do not understand.* Use proper tools; replace or repair broken or damaged equipment.* When starting an engine after repairs have been made to the fuel system, make provisions for shutting off the engine's intake air supply (to stop the engine), in case there is an overspeed on start-up.* Start the engine only from the cab. Never short across the starter terminals or the batteries, as this could bypass the engine neutral-start system, as well as damage the electrical system.Pressure Air and Water
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.The maximum air pressure must be below 30 psi (205 kPa) for cleaning purposes.Wear eye protection at all times when cleaning the cooling system. Pressurized water could cause debris to be blown and result in personal injury.Fluid Penetration
Always use a board or cardboard when checking for a leak. Escaping fluid under pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury or possible death.If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.Asbestos Information
Caution should be used to avoid breathing dust that may be generated when handling components containing asbestos fibers. If this dust is inhaled, it can be hazardous to your health.Components in Caterpillar products that may contain asbestos fibers are brake pads, brake band and lining assemblies, clutch plates and some gaskets.The asbestos used in these components is usually bound in a resin or sealed in some way. Normal handling is not hazardous as long as airborne dust which contains asbestos is not generated.If dust is present, which may contain asbestos, there are several common sense guidelines that should be followed.* Never use compressed air for cleaning.* Avoid brushing or grinding materials containing asbestos.* For clean up, use wet methods or a vacuum equipped with a high efficiency particulate air (HEPA) filter.* 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. (For example in the U.S.A., OSHA requirements as set forth in 29 CFR 1910.1001).* Follow environmental rules and regulations for disposal of asbestos.* Avoid areas where airborne asbestos particles may be present.Lines, Tubes and Hoses
Do not bend or strike high pressure lines. Do not install damaged lines, tubes or hoses.Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause fires.Inspect all lines, tubes and hoses carefully. Do not use your bare hands to check for leaks. Tighten all connections to the recommended torque.* End fittings damaged or leaking.* Outer covering chafed or cut and wire reinforcing exposed.* Outer covering ballooning locally.* Evidence of kinking or crushed areas of the flexible part of the hose.* Armoring embedded in the outer cover.* End fittings displaced.Burn Prevention
Do not touch any part of an operating engine. Allow the engine to cool before any repair or maintenance is performed on the engine.Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.Coolant
At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot water. When pressure is relieved rapidly, this hot water can turn into steam.Radiators must be kept clean and free from trash to prevent possible overheating.Allow cooling system components to cool before draining.Check the coolant level only after the engine has been stopped and the filler cap is cool enough to remove with your bare hand.Remove the cooling system filler cap slowly to relieve pressure.To prevent personal injury, do not step up on engine to remove the filler cap, if applicable. Use an adequate ladder.Any contact with hot water or steam can cause severe burns.Cooling system supplemental coolant additive contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.Batteries
Battery electrolyte contains acid and can cause injury. Avoid contact with the skin and eyes.Do not smoke when observing the battery electrolyte levels.Always wear protective glasses when working with batteries.Fire or Explosion Prevention
Determine whether the engine will be operated in an environment in which combustible gases could be drawn through the air inlet system. These gases could cause the engine to overspeed, which in turn could destroy the engine and result in bodily injury or property damage.A manual shutdown device such as an air inlet shutoff is recommended to be installed in the air inlet piping for vehicles handling flammable gases or working in an area where escaping flammable gases could be encountered. This will prevent possible engine runaway or possible engine explosion.If your application involves
