components of water. Because of the loss of these gases and
the lowering of the electrolyte level, it will be necessary to
add pure, clean distilled water to bring the fluid to the proper
level. After filling, charge the battery to raise the specific
gravity to1.270 or greater.
OFF SEASON STORAGE
To prevent battery damage during extended periods of non-
use, the following basic maintenance items must be
performed.
1. Remove battery from machine and wash the case and
battery tray with a mild solution of baking soda and water.
Rinse with lots of fresh water after cleaning.
2. Using a wire brush or knife, remove any corrosion from
the cables and terminals.
3. Make sure the electrolyte is at the proper level. Add
distilled water if necessary.
4. Charge at a rate no greater than 1/10 of the battery's amp/
hr. capacity until the electrolyte's specific gravity reaches
1.270 or greater.
5. The battery may be stored either in the machine with the
cables disconnected, or on a piece of wood in a cool place.
NOTE: Stored batteries lose their charge at the rate
of 1% per day. They should be fully recharged every
30 to 60 days during a non-use period. If stored
during winter months, the electrolyte will freeze at
higher temperatures as the battery discharges. The
chart indicates freezing points by specific gravity.
CHARGING PROCEDURE
Charge battery with a charger no larger than 1/10 of the
battery's amp/hr. rating and for as many hours as needed to
raise the specific gravity to 1.270 per cell or greater.
STARTER SYSTEM
DYNAMIC TESTING OF THE ELECTRIC
STARTER SYSTEM
CONDITION: Starter fails to turn the starter motor or it turns
the starter motor slowly
NOTE: Be sure the engine crankshaft is free to turn
before proceeding. For this test a digital multitester
CAUTION
DO NOT ALLOW ANY OF THE BAKING SODA SOLUTION TO
ENTER THE BATTERY OR THE ACID WILL BE NEUTRALIZED.

WARNING
BATTERY ELECTROLYTE IS POISONOUS. IT CONTAINS AC-
ID!
S
ERIOUS BURNS CAN RESULT FROM CONTACT WITH THE
SKIN, EYES, OR CLOTHING.
ANTIDOTE:
EXTERNAL: F
LUSH WITH WATER.
INTERNAL: D
RINK LARGE QUANTITIES OF WATER OR
MILK. FOLLOW WITH MILK OF MAGNESIA, BEATEN EGG, OR
VEGETABLE OIL. CALL PHYSICIAN IMMEDIATELY.
EYES: F
LUSH WITH WATER FOR 15 MINUTES AND GET
PROMPT MEDICAL ATTENTION.
B
ATTERIES PRODUCE EXPLOSIVE GASES. KEEP SPARKS,
FLAME, CIGARETTES, ETC. AWAY. VENTILATE WHEN
CHARGING OR USING IN CLOSED SPACE. ALWAYS SHIELD
EYES WHEN WORKING NEAR BATTERIES.
KEEP OUT OF REACH OF CHILDREN.
WARNING
THE GASES GIVEN OFF BY A BATTERY ARE EXPLOSIVE. ANY
SPARK OR OPEN FLAME NEAR A BATTERY CAN CAUSE AN
EXPLOSION WHICH WILL SPRAY BATTERY ACID ON ANYONE
CLOSE TO IT. IF BATTERY ACID GETS ON ANYONE, WASH
THE AFFECTED AREA WITH LARGE QUANTITIES OF COOL
WATER AND SEEK IMMEDIATE MEDICAL ATTENTION.
