Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the batteries and charge them fully (see
Battery Service).
2. Either store batteries on a shelf or on the machine.
3. Leavecablesdisconnectedifthe batteries arestored
on the machine.
4. Store batteries in a cool atmosphere to avoid quick
deterioration of the battery charge.
5. To help prevent the batteries from freezing, make
sure they are fully charged (see Battery Service).
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
than if the machine is stored in a location where temper-
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.
Nausea may result if thegases are inhaled.Un-
plug charger from electrical outlet before con-
necting or disconnecting charger leads to or
from battery posts.
IMPORTANT: Do not remove fill caps while clean-
ing.
2. Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery
case clean because a dirty battery will discharge slowly.
A. Clean battery by washing entire case w ith a solu-
tion of baking soda and water. Rinse with clearwater.
B. Coat battery posts and cable connectors with
Battery Terminal Protector (Toro Part No. 107--0392)
or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on terminals to provide
good electrical contact.
WARNING
Connecting cables to the wrong battery post
could result in personal injury and/or damage
to the electrical system.
4. If corrosion occurs at battery terminals, disconnect
cables. Always disconnect negative (--) cables first.
Clean clamps and terminals s eparately. Reconnect
cables with positive (+) cables first. Coat battery posts
and cable 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. Maintain cell level with distilled or demineralized wa-
ter. Do not fill cells above the fill line.
