Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
Park the machine on a level surface and engage the parking brake. Stop the engine. 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.Note: Articulate the machine to the left in order to get better access to the crankcase drain valve.
