second key in the Tractor ignition).

There will be an amount of electrolyte (acid) in

the container after battery is filled. This should

be disposed of and not u sed at a Iater date to

refill Tractoror any other battery. Using a common

5 gallon polyethylene garbage can or pail, fill

with a minimum of four inches of water. Avoid

spillage on person or clothing, add left over

electrolyte to water. Then sodium bicarbonate

(baking soda) shou Id be added and the mixture

stirred or agitated until the addition of bicar-

bonate no longer causes foaming. Agitate with a

wooden or plastic stake or stick only. It will

now be safe to dispose of this down a reguiar

sewage system. Since the product is well neu-

tralized, no criticism from authorities should

result,

It is preferable, where permissible, to burn the

empty acid pak to prevent possible further con-

- S -

NOT E: Your

ine

carburetor

breathes

through

the

air

cleaner.

Your

engine

with

a

dirty

air

cleaner

will

have

a

very

difficult

time

try

ing

to

do

the

same

job

as

an

engine

with a

clean

one.

If your

air

cleaner

is

only

50%

efficient,

it

will

reduce

the

efficiency

of

the

engine

by

at

least

1/3

of

its

horsepower

rating.

A

dirty

air

cleaner

will

cause

a

premature

bui Idup

of

carbon

in

the

exhaust

and

cylinder

area.

There

will

also

be

a

noticeable

loss

of

power.

The

spark

will

also

foul

prematurely.

It

also

raises

the

temperature

of

and you

can

expect

higher

maintenance

costs

and a

shorter
