Removal Procedure
| NOTICE |
|---|
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. |
| NOTICE |
|---|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
 |
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. Turn the disconnect switch OFF when draining and/or removing any fuel system components. |
 |
Note: Put identification marks on all hose assemblies, on all harness assemblies, and on all tube assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
