STRAINER AS 4810396 - Caterpillar

Procedure for Changing Engine Oil and Filter
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Note: If the sulfur content in the fuel is greater than 1.5 percent by weight, use an oil that has a TBN of 30 and reduce the oil change interval by one-half.Note: Drain the crankcase while the oil is warm. This allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining the oil and the particles will recirculate in the engine lubrication system with the new oil.
Park the machine on a level surface. Stop the engine.Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information on Containing Fluid Spillage.
