TUBE AS 3728290 - Caterpillar

Care must be used in order to ensure that the fluids are contained during the inspection, maintenance, testing, adjusting, and repair of the engine. Make provision to collect the fluid with a suitable container before any compartment is opened or before any component is disassembled. Refer to the Special Publication, NENG2500. This publication explains the items that are needed for collecting and containing fluids that are used in Caterpillar engines. Dispose of fluids according to local regulations.
Drain water and sediment from the fuel tank every 10 service hours or daily. Use a suitable container for collecting the contaminated fuel. Open the drain valve for the fuel tank in order to allow contaminated fuel to drain into the container. Close the drain valve.
Inspect the fuel in the container. Water will be visible as a separate layer below the fuel. Sediment will be seen floating in the water and/or in the fuel.
If no water and/or sediment is observed, proceed with normal operation. Otherwise, repeat the draining procedure until all traces of water and sediment have been removed.
For the location of the drain valve for the fuel tank, see the Operation and Maintenance Manual for the machine.
