Battery Maintenance (FS 520 / FS 524):
This engine starting battery (RR) is a sealed unit and will never require the addition of water. Keep the top of the battery and the cable connections clean and free of corrosion. Coat the connections with a high tempera- ture grease or petroleum jelly. Periodically check the battery by measuring its voltage with a DC voltmeter. A fully charged battery will be 12.8 volts. It is recom- mended that voltage checking and charging be done at the battery cable on the starter motor at the front of the saw.
