Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. 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 Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines.
Dispose of all fluids according to local regulations and mandates.
2. Drain the contents from the tank. Disassemble the bolts (3), washers (4), and clips (5) used to attach the fuel line. Disassemble the fuel line from the tank. Retain all components for reassembly in Step 7.3. Disassemble the fuel tank from the machine.
Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc.
Welding can cause fumes, burn skin and produce ultraviolet rays.
Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working.
Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death.
Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts.
