ly, turn the wheels a little every month in order
to prevent the tires from becoming degraded
in one spot.

prevent moisture from entering it.

it in a cool, dry place and charge it once a
month. Do not store the battery in an exces-
sively cold or warm place [less than 0 °C (30
°F) or more than 30 °C (90 °F)]. For more in-
formation on storing the battery, see page
8-39.
