Itshould be used within 2 years from the date of manufacture(printed on the container).Important note on bio-degradable chain oilsIf you are not planning to use the saw again for an extendedperiod of time, empty the oil tank and put in a small amountof regular engine oil (SAE 30), and then run the saw fora time. This is necessary to flush out all remaining bio‑degradable oil from the oil tank, oil‑feed system, chain andguide bar, as many such oils tend to leave sticky residuesover time, which can cause damage to the oil pump or otherparts.The next time you use the saw, fill the tank with BIOTOPchain oil again.
