Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
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 Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Refer to the Operation and Maintenance Manual, "Access Doors and Covers" for the location of the service points.Clean the area around the drain plug for the differential and the transmission before removing the drain plug. Clean the area around the dipstick/fill cap before removing the dipstick/fill cap. Operate the engine until the transmission and differential oil is warm. Park the machine on a level surface and engage the parking brake. Lower the blade and apply slight down pressure to the blade. Stop the engine.Note: Drain the transmission and differential case 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 case. The particles will not be removed by draining the oil and the particles will recirculate in the lubrication system with the new oil.
