Changing the Engine Oil

The engine oil will be hot. Avoid skin contact with the used engine oil.

1.Move snowthrower to a level surface.

2.Run snowthrower until all fuel has been depleted.

3.Remove ignition key.

4.Place an oil drain pan under the oil drain plug, remove the oil drain plug, and tip the snowthrower backward and drain the used oil in the oil drain pan (Figure 23).

5.After draining the used oil, return the snowthrower to the operating position.

6.Install the oil drain plug and torque to 145-150 in-lbs (17 N-m).
