1. Place the machine on a level place.
2. Warm up the engine for several minutes and
stop it. Wait at least ten minutes for the oil to
drain back into the crankcase before check-
ing the oil level.NOTE:_ Be sure to wait at least ten minutes until the oil lev-
el settles before checking. _3. Remove the dipstick and wipe it off with a
clean rag. Insert the dipstick in the filler hole
without screwing it in.
4. Remove the dipstick and inspect the oil level.
5. The oil level should be between the maxi-
mum and minimum marks. If the level is low,
add oil to raise it to the proper level.CAUTION:_ Make sure no foreign material enters the
crankcase. _

5. After checking, tighten the oil gallery bolt to
the specified torque.CAUTION:_ Be sure to inspect the oil pressure after replac-
ing the engine oil. _
