Cleaning battery
Keep battery clean by wiping
it
with a clean
cloth every
50
hours operation or whenever
dirt appears excessive. Remove any corro-
sion, and wash terminals with a solution of
baking soda and water.
Check vent holes
in
the battery caps to make
sure -they are open. Cable connectors must
be free of dirt and well tightened.
Tighten connectors to reduce corrosion.

Storing banery
A
CAUT,ON
Store
battery
out
of reach of children.
If tractor is stored for the winter or for any
period of
30
days or more, remove the
battery and store in a cool dry place where
no freezing will occur. Check the battery
every
30
days and charge them if necessary.
7)
Cold weather battery service
Battery has less capacity in cold weather and
carries a heavier load in starting the engine,
and therefore require more attention.

Alternator
a)
If
tractor
is
to
be
operated without battery
(using a booster battery for starting), do
not interrupt the circuit by switching off
the starter switch before stopping engine.
Further,
it
is recommended to use addi-
tional current (lights) while engine is run-
ning.
b) When engine
is
running, do not short cir-
cuit or ground the alternator and regulator
terminals.
A
correctly filled and well charged battery
is
d)
the best protection against freezing.
Check battery more often in winter.
C)
Connect battery or battery charger in the
proper polarity (positive to positive and
negative to negative). If they are impro-
perly connected, the rectifier diodes will be
immediately destroyed.

Starter
When starting engine, never operate starter for
more than
10
seconds at the same time. If the
engine does not start within this period, allow at
least one minute for proper cooling of the starter.
If starter fails to operate after the key switch has
been turned all the way clockwise, the whole
starter system must
be
throughly checked.
Check
the specific gravity of battery and make sure that
no cable is broken or worn and that no cable con-
nection is loose or corroded.
/-.
If starter
is
disconnected for any reason, connect
wires as shown in the following illustration.
Before performing electric welding jobs on
the tractor, disconnect the one terminal
plug
(N/F)
and two terminals
(A
and
E)
at
alternator. Connect ground terminal of
welding apparatus directly to the part being
welded.
Before performing electrical repairs on
alternator or starter, disconnect
battew
ground cables. This will avoid the damage
from short
circuiting.
