Battery Care
1. Battery electrolyte level must be properly main-
tained. The top of the battery must be kept clean. lf the
machine is s tored in a location where temperatures are
extremely high, the battery will discharge more rapidly
thanifthemachineisstoredinalocationwheretemper-
atures are cool.
WARNING
Wear safety goggles and rubber gloves when
working with electrolyte. Charge battery in a
well ventilated place so gasses produced while
charging can dissipate. Since the gases are ex-
plosive,keepopen flames andelectricalsparks
away from the battery; do not smoke. Nausea
