VP Models are equipped with 24 volt, 10 amp output bat- tery chargers (U.S.A. - 120 Volt AC input/60Hz and Brazil - 220 Volt AC input/60 Hz). The battery charger includes a microprocessor controlled automatic charge sensing cir- cuit which can determine cell voltage and regulate charger output as required. The charger automatically ter- minates charging when a full battery charge is acheived. Also a built-in interlock device prohibits driving the machine while the battery charger is plugged in.
Battery Maintenance and Safety Practices
As with any wet cell battery, check the electrolyte level of the batteries often, adding only distilled water when required. When fully charged, battery fluid level should be 1/8" below vent tubes.
