2.Run snowthrower until all fuel has been depleted.

3.Remove ignition key.

7.Clean around the oil filler cap/dipstick (Figure 24).

8.Unscrew the oil fill cap/dipstick and remove it (Figure 24).

9.With the snowthrower in the operating position, care- fully pour oil into the oil fill hole until "Full" on the fill cap/dipstick line (Figure 26).

Max fill: 18 oz. (0.5 l), type: automotive detergent oil with an API service classification of SJ, SL, or higher.
