Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the battery and charge it fully (see Battery
Service in this section).
2. Either store battery on a shelf or on the machine.

Battery Care
1. Battery electrolyte level must be properly main-
tained. The top of the battery must be kept clean. lf the
machine is stored 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 explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
