LUBRICATION
Use only high quality detergent oil rated with API service
classifi cation SF-SJ. Select the oil’s SAE vis cos i ty grade
according to your expected temperature.
NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the tractor is not used for 25 hours in one
year.
Check the crankcase oil level before starting the engine
and after each fi ve (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil fi ller plug securely
each time you check the oil level.
