BATTERY CARE
1.
Battery eIectroIyte IeveI must be properIy
maintained and the top of the battery kept clean. If the
Aerator is stored in a location where temperatures are
extremeIy high, the battery wiII run down more rapidIy
than if the machine is stored in a location where
temperatures are cool.
2.
Check the electroIyte leveI every 25 operating
hours or, if machine is in storage, every 30 days.
3.
Maintain ceIl IeveI with distiIled or demineraIized
water. Do not fill ceIIs above the bottom of the spIit ring
inside each ceII.
4.
Keep top of battery cIean by washing periodicaIIy
with a brush dipped in ammonia or bicarbonate of soda
soIution. Flush the top surface with water after
cIeaning. Do not remove the fiII caps whiIe cIeaning.
5.
Battery cabIes must be tight on terminaIs to
provide good electricaI contact.
6.
If corrosion occurs at terminaIs, disconnect
cabIes, negative (-) cabIe first and scrape cIamps and
terminaIs separateIy. Reconnect cabIes, positive cabIe
first and coat terminaIs with petroIeum jelIy.
BATTERY STORAGE
If the machine wiII be stored more than 30 days,
remove the battery and charge it fuIIy. Either store it on
the shelf or on the machine. Leave the cabIes
disconnected if stored on the machine. Store the
battery in a cool atmosphere to avoid quick
deterioration of the charge in the battery.
