the standard fashion.
1 0 .A boost charge is only for emergencies. It
partially charges the battery at a high rate and in
a short time. When using a boost-charged
b a t t e r y, it is necessry to recharge the battery as
early as possible after the operation has been
finished. Failure to do this extremely affects the
service life due to overdischarge.
I M P O RTANT :
( 1 )When connecting the battery, do not reverse the
polarities. Connection with reverse polarities
causes troubles to the battery and electrical
system in the tractor.
( 2 )When disconnecting the cord from the battery, start
with the negative terminal first, when connecting
start with the positive terminal first. Reversing the
steps may cause short-circuiting, should a metalic
tool touch the terminals.
( 3 )If the tractor is to be operated for a short time
without battery(using a slave battery for starting),
do not, under any circumstances, interrupt the
circuit by switching off the key switch before
stopping the engine by means of fuel pump shut
off cable. Use additional current(lights) while
engine is running. Insulate terminal of battery
cable before starting by means of slave battery. If
this advice is disregarded, damage to alternator
and regulator may result.
- Direction for Storage
1. When shutting down the tractor for long period of
time, remove the battery from the tractor, adjust
the electrolyte to the proper level and store in a
dry place out of direct sunlight.
2 .The battery self-discharges even while it is
stored, Recharge it once a month in hot seasons
and once every two months in cold seasons.
I M P O RTANT :
•The tractor has been shipped with dry-type
b a t t e r y. Your dealer will fill electrolyte and charge
for use for the first time.
- Charging Dry Type Battery
1. Remove vent plugs and discard temporary
sealing cardboards and tapes.
2. Fill each cell with electrolyte having a specific
gravity given in Table 1 up to highest level
marked on the battery case side.

3. After standing for 2 or 3 hours correct the
electrolyte to former level.
4. Connect positive terminal(+) of battery, with
positive terminal of D.C. charging unit, and
negative terminal(-) with negative terminal.
5. Batteries are preferably charged by current
showed in Table 2. Keep vent plugs removed
during charging.

6. Check temperature of electrolyte, if it reaches
4 0 o C ( 1 0 5 o F), lower the charging rate. When
temperature is too high, reduce charging rate
and charge for a proportionately longer period.
7. If the tractor is stored after original charge,
periodically recharge as shown below :

A battery is fully charged when the cell are all
gassing freely and the specific gravity ceases to
rise for three consecutive readings taken at hour
intervals. Specific gravity shall then be adjusted
to showed in Table 1.
8. Check electrolyte level two hours after charging
is finished and correct it. if necessary, oil by
adding distilled water.
