Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the battery from the machine and charge it
fully (see Battery Service in this section).
2. Either store battery on a shelf or on the machine.
3. Leavecablesdisconnectedifthebatteryisstoredon
the machine.
4. Storebatteryinacoolatmospheretoavoidquickde-
terioration of the battery charge.
5. Tohelppreventthebattery fromfreezing, makesure
it is fully charged (see Battery Service in this section).
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 locationwhere temperatures are
extremely high, the battery will discharge more rapidly
thanifthemachineisstoredinalocationwheretemper-
atures are cool.
Wear safety goggles and rubber gloves when
working with electrolyte. C harge battery in a
well ventilated place so gasses produced
while charging can dissipate. Since the gases
are explosive, keep openflames and electrical
sparks away from the battery; do not smoke.

CAUTION
IMPORTANT: Do not remove battery fill caps while
cleaning.
2. Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery

tionofbakingsodaandwater.Rinsewithclearwater.
B. Coat battery posts and cable connectors with
BatteryTerminalProtector(ToroPartNo.107--0392)
or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on terminals to provide
good electrical contact.
Connecting battery cables to the wrong bat-
tery post couldresultin personal injuryand/or
damage to the electrical system.
CAUTION
4. If corrosion occurs at terminals, disconnect cables.
Always disconnect negative (--) cable first. Clean
clamps and terminals separately. Reconnect cables
withpositive(+)cablefirst.Coatbatterypostsandcable
connectors with Battery Terminal Protector (Toro Part
No. 107--0392) or petroleum jelly to prevent corrosion.
5. Check electrolyte level every 25 operating hours,
and every 30 days if machine is in storage.
6. Maintaincelllevelwithdistilledor demineralizedwa-
ter. Do not fill cells above the fill line.
