service classification SF, SG or SH. Select the oil’s
viscosity grade according to your expected operating
temperature.
Colder
32‘’F
-► Warmer
5W30
SAE 30
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these multi
viscosity oils will result in increased oil consumption
when used above 32°F. Check your oil level more
frequently to avoid possible engine damage from
running low on oil.
• Use engine oil provided. Remove oil fill dipstick.
See figure 12. With chipper-vacuum level, use a
funnel to fill engine with oil to FULL mark on dip
stick. Capacity is approximately 20 ounces. Be

20 oz. of oil. Tilt chipper-vacuum toward the left
