BATTERY

The

battery

installed

in

the

654

tractor

is a

dry

charged

battery.

It

is

important

that

you

this

battery

to

insure

good

service

and

long

life.

1. Remove

vent

caps"

Remove

or

destroy

any

seal·

ing

device

which

may

have

been

2. Fill

each

cell

of

the

battery

to

the

proper

level

with

the

battery

electrolyte.

NOTE.

Temperature

of

battery

and

electrolyte

at

time

of
