• When the battery is being activated, hydrogen and oxygen
gases in the battery are extremely explosive. Keep open
sparks and flames away from the battery at all times,
especially when charging the battery.
• When charging battery, ensure the vent caps are securely
in place. (if equipped)
• When disconnecting the cable from the battery, start with
the negative terminal first.
When connecting the cable to the battery, start with the
positive terminal first.
• Never check battery charge by placing a metal object
across the posts.
Use a voltmeter or hydrometer.
1. Make sure each electrolyte level is to the bottom of vent wells,
if necessary add distilled water in a well-ventilated area.
2. The water in the electrolyte evaporates during recharging.
Liquid shortage damages the battery.
Excessive liquid spills over and damages the tractor body.
3. To slow charge the battery, connect the battery positive terminal
to the charger positive terminal and the negative to the negative,
then recharge in the normal manner.
4. A boost charge is only for emergencies. It will partially charge
the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to recharge
the battery as early as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte is between 1.27 and
1.29, the charging is completed.
6. When exchanging an old battery for a new one, use battery of
equal specification shown in table 1.
Table 1
Q Battery Storage
1. When storing the tractor for long periods of time, remove the
battery from tractor, adjust the electrolyte to the proper level and
store in a dry place out of direct sunlight.
2. The battery self-discharges while it is stored.
Recharge it once every three months in hot seasons and once
every 6 months in cold seasons.
