Before you service the machine or before you repair the machine, attach a "Do Not Operate" warning tag or a similar warning tag to the start switch or to the controls.
For more information about these warning tags, see Special Instruction, SEHS7332 or consult your Caterpillar Dealer.
Know the width of your equipment in order to maintain proper clearance near fences, boundary obstacles, etc.
Wear a hard hat, protective glasses and other protective equipment in order to suit job conditions.
Do not wear jewelry. Do not wear clothing that is loose. Jewelry and clothing that is loose can snag on controls or on other parts of the machine.
Ensure that all protective guards and all covers are secured in place on the machine.
Keep the machine free from foreign material. Check the deck, the walkways and the steps. Remove debris, oil, tools and other items.
Secure all loose items that are not a part of the machine. Secure lunch boxes, tools and other items.
Know the appropriate job site hand signals. Also, know the personnel that are authorized to give hand signals. Accept hand signals from one person only.
Do not smoke when you service an air conditioner. Also, do not smoke if refrigerant gas may be present. Inhaling the fumes that are emitted from a flame that contacts air conditioner refrigerant can cause bodily harm or death. Inhaling gas from air conditioner refrigerant through a lighted cigarette or any other means of smoking can cause bodily harm or death.
Never put maintenance fluids into glass containers. Drain all liquids into a suitable container.
When you discard liquids, obey all local regulations.
Use all cleaning solutions with care.
Report all necessary repairs.
Do not allow unauthorized personnel on the machine.
Unless you are instructed otherwise, perform maintenance with the following conditions:
- The machine parked on level ground.
- The dump body lowered to the frame. The dump body must be secured if the dump body is raised.
- The transmission control must be in the NEUTRAL position.
- The parking and secondary brake control moved to the ENGAGED position.
- The engine stopped.
- The engine start switch must be in the OFF position and the key must be removed.
- The disconnect switch must be in the OFF position and the key must be removed.
Pressure Air
Pressure air can cause personal injury. When pressure air is used for cleaning, wear a protective face shield, protective clothing and protective shoes.
The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes.
Fluid Penetration
When you check for a leak, use a board or cardboard. 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 obtain treatment immediately. Seek treatment from a doctor that is familiar with this type of injury.
Asbestos Information
Caterpillar equipment and replacement parts that are shipped from Caterpillar are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts. If any replacement parts that contain asbestos are used, the following guidelines should be used in handling these parts and 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 use is not hazardous, unless airborne dust that contains asbestos is generated.
If dust which can contain asbestos is present, there are several guidelines that should be followed:
- Never use compressed air for cleaning.
- Avoid brushing materials that contain asbestos.
- Also avoid grinding materials that contain asbestos.
- Use a wet method in order to clean up asbestos materials.
- You may also use a vacuum that is equipped with a highly efficient filter that cleans particulate air.
- 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 USA, use Occupational Safety and Health Administration requirements. These OSHA requirements can be found in "29 CFR 1910.1001".
- Obey environmental rules and regulations for the disposal of asbestos.
- Stay away from areas that might have asbestos particles in the air.
Containing Fluid Spillage
Care must be taken in order to ensure that fluids are contained while you do the following procedures.
- Inspect the machine.
- Maintain the machine.
- Test the machine.
- Adjust the machine.
- Repair the machine.
Be ready to collect the fluid with suitable containers before you open any compartment and before you disassemble any component which contains fluids.
Refer to Special Publication, NENG2500, "Tools and Shop Products Guide" for the following items:
- Tools that are suitable for collecting fluids and for containing fluids
- Equipment that is suitable for collecting fluids and for containing fluids
Obey all local regulations for the disposal of liquids.
