CHECKING AND CHANGING THE ENGINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it into the household trash. WARNING: Used motor oil may cause irritation or
cancer
of the skin if left in contact with the skin for prolonged periods of time. Wash your handsthoroughly with soap and warm water assoon as possible after handling used oil.
