• Mishandling the battery shortens the service life
and adds to maintenance costs.
The original battery is maintenance free, but
needs some servicing.
If the battery is weak, the engine will be difficult
to start and the lights will be dim. It is important
to check the battery periodically.
• When exchanging an old battery for a new one,
use the battery of equal specification in the
following table.
Battery type 26R-560
Volts 12 V
Reserve capacity 86 min
Cold cranking amps 560
Normal charging rate 8.6 A
For non-accessible maintenance-free type batteries
Maintenance-free, non-accessible batteries are
designed to eliminate the need to add water. Yet the
volume of electrolyte above plates may eventually
become depleted due to abnormal conditions such as
high heat or improper regulator setting. Use a voltmeter
to check the state of charge. See the following table to
determine if charging is necessary.
Battery voltage Reference state of charge
12.6 100% (Full charge)
12.4 75%
12.2 50%
12.0 25%
11.8 0%
1.1 Battery charging
WARNING
To avoid serious injury or death:
• 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 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.
• To prevent short circuit, before charging, make
sure to remove the metal-battery-holder.
• Never check the battery charge by placing a
metal object across the posts.
Use a voltmeter or hydrometer.
(1) Battery
(2) Clamp (3) Battery holder
IMPORTANT :
• Since the metal-battery-holder can crack, do not
tighten it too much.
• 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 standard fashion.
• 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 recharge the battery will shorten the
service life of battery.
• When the specific gravity of electrolyte is shown in
the following table, the charging is completed.
Specific gravity of electrolyte Between 1.27 and 1.29
1.2 Dealing with the battery when storing
the tractor for a long period
1. Remove the battery from the tractor.
2. Adjust the electrolyte to the proper level.
3. Store the battery in a dry place out of direct
sunlight.
The battery self-discharges while it is stored.
Recharge the battery once every 3 months in hot
seasons and once every 6 months in cold seasons.
2. Cleaning the air cleaner element
WARNING
To avoid serious injury or death:
• Be sure to stop the engine and remove the key
before cleaning the air cleaner element.
PERIODIC SERVICE SERVICE EVERY 100 HOURS
