NOTICE

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" for tools and supplies suitable to collect and contain fluids on Caterpillar products.

Dispose of all fluids according to local regulations and mandates.


Note: Put identification marks on all hoses, on all hose assemblies on all wires, and on all tube assemblies for installation purposes. Plug all hose assemblies and plug all tube assemblies. This helps prevent fluid loss, and this helps keep contaminants from entering the system.

  1. Drain the hydraulic tank into a suitable container for storage or disposal.
