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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.

Dispose of all fluids according to local regulations and mandates.

Hot oil and components can cause personal injury.

Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.

Note: Install caps and plugs on all openings to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal components.

Note: For easier assembly, mark all hose assemblies, tube assemblies, wire harnesses, and cables for identification purposes.
