GAS AND OIL FILL-UP
OIL
Only use high quality detergent oil rated with API
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
careful not to overfill. Oil bottle provided contains
20 oz. of oil. Tilt chipper-vacuum toward the left
(from behind the hopper), then re-level. Check oil
level. Refill to FULL mark on dipstick if necessary.
Replace dipstick and tighten.
