BATTERY MAINTENANCE (FIG. 24)
MAINTENANCE
Fig. 24
When starter operates properly and battery connections
are clean and tight, but cranking difficulty is experi-
enced, battery may not be charged. Battery should be
taken to a qualified service station and tested, or charge
the battery with battery charger (See page 7)
If engine will not start right away under normal cranking
speed, continued cranking will run down the battery and
may cause damage to the starter. Check ignition and fuel
systems and correct any faults.
The battery should be kept clean.
If the top has an accumulation of dirt or grease, remove
the battery from lawn tractor for cleaning. The battery
should be cleaned with a mild solution of baking soda
and water. Brush this on, keeping vent plugs tightly in
place to prevent any solution from entering cells.
Allow the solution to work for a few minutes, then rinse
with clean water and wipe battery dry.
If battery terminals are corroded, clean with a wire brush
and coat terminals with petroleum jelly.

DANGER
Be sure to reinstall battery in the same position and
properly reconnect battery cables (red to positive,
black to negative).
Proper care will lengthen battery life. When replacement
becomes necessary, use battery of same size and type for
continued trouble-free service (see Repair parts manual).

DANGER
Always disconnect negative (black) cable first.
Removing positive cable first can result in sparks if
the wrench touches any metal surface. Be sure battery
hold-down bracket does not touch battery terminals
and causes a spark.
