How Do You Change the Oil in a Two-Stage Yard Machine Snow Blower?
To change the oil in a Yard Machine snow blower, first run the machine out of fuel. Remove the sparkplug to prevent it from starting during the oil change. Take off the oil cap and dipstick, tilt the snow blower to the side and remove the oil. Allow it to drain into a disposable container. Set the snow blower upright and on a flat surface to add motor oil, and put the dipstick and oil cap back in place.
MTD Products, the creator of Yard Machine snow blowers, suggests the use of a high detergent motor oil with a viscosity of 5W-30. If synthetic oil is used, the viscosity should be 0W-30. The oil should be 4-cycle and should at least meet the SF or SG classification. SJ, SL or SM classifications are also acceptable.
The oil should be checked before each use and after five hours of continuous use. Turn the cap to the left, and remove it. Clean the dipstick with a clean rag, replace and tighten it. Remove it again, and observe the oil level; it should fall between the high and low indicators on the dipstick. If the oil level is low, carefully add more, being careful not to exceed the oil capacity stated in the manufacturer’s manual.
