Wear safety glasses toshield your eyes and rubber gloves to protectyour hands.• Fill the battery where clean water is alwaysavailable for flushing the skin.• Keep top of battery clean by washing periodically witha brush dipped in ammonia or bicarbonate of sodasolution. Flush the top surface with water after cleaning.Do not remove the fill cap while cleaning.• Battery cables must be tight on terminals to providegood electrical contact.CALIFORNIAProposition 65 WarningBattery posts, terminals, and related accessoriescontain lead and lead compounds, chemicalsknown to the State of California to cause cancerand reproductive harm. Wash hands afterhandling.Warning• If corrosion occurs at terminals, disconnect cables,negative (–) cable first and scrape clamps and terminalsseparately. Reconnect cables, positive (+) cable first andcoat terminals with petroleum jelly.• Check the electrolyte level every 25 operating hours or,if machine is in storage, every 30 days.• Maintain cell level with distilled or demineralizedwater. Do not fill cells above fill line.• If machine will be stored for more than 30 days, removethe battery and charge it fully. Either store it on theshelf on the machine. Leave the cables disconnected ifstored on the machine. Store the battery in a coolatmosphere to avoid quick deterioration of the charge inthe battery. To prevent battery from freezing, make sureit is fully charged. The specific gravity of a fullycharged battery is 1.250.Charging the battery produces gasses that canexplode.Never smoke near the battery and keep sparks andflames away from battery.WarningBattery terminals or metal tools could shortagainst metal tractor components causing sparks.Sparks can cause the battery gasses to explode,resulting in personal injury.• When removing or installing the battery, do notallow the battery terminals to touch any metalparts of the tractor.• Do not allow metal tools to short between thebattery terminals and metal parts of the tractor.Warning
