NOTE: Although multi-viscosity oils (5W30, ! 0W30, etc.)
improves starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32"C. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil
Change the oil after the first two hours of operation and
every 50 hours thereafter or at least once a year if the
tractor is not used for 50 hours in one year°
Check the crankcase oil level before starting the engine
and after each eight (8) hours of continuous use_
BILITJES
TO CHANGE ENGINE OIL (See Figs. '14 and 15)
