Park the tractor on flat ground and bring the lifter arm to its lowest height. Shut off the engine. Remove the lifter
cover dipstick and check the oil level. If the level is under the lowest mark, fill with hydraulic oil until it is between
the upper and lower marks. Drain the used oil when changing hydraulic oil and then fill with fresh hydraulic oil.
Normally the maintenance-free battery does not require any special maintenance. Water does not have to be added to
maintain the level of electrolyte since the battery is sealed. You can observe the power levels from the view hole in
the battery: Green = full power; Grey = lack of power; Dark = no power.
As part of the tractor’s electrical system the battery requires some system level maintenance.
1. Check the status of the battery. Make sure the case is not cracked or leaking, and the battery is secured in place.
2. The battery should be charged under the following conditions:
The engine is slow to start and/or the lights are faint.
The inspection hole becomes grey. It should be replaced when the inspection hole becomes dark.
The battery is under voltage. Measure the terminal voltage when discharging. There is a problem with a
12V battery if the output voltage is lower than 10.5V.
3. When being stored, the battery should be charged monthly. The charging method is as follows: charge the battery
by 0.1C20A (C20 is power capacity for 20h). When the terminal voltage for the 12V battery reaches
14.4±0.05V, you can continue charging for another 5h.
4. When removed from the tractor for any reason the battery should be stored in a clean, dry and well-ventilated area
with a temperature that is 32–104F. The battery should be handled with care and stored right side up.
5. The power supply should be tightly connected to the battery terminals, in order to prevent the terminal from
melting when the tractor is started. In order to avoid terminal oxidation or corrosive, the exterior of terminal
should be coated with petroleum jelly.
6. Keep the exterior terminals of the battery clean.
7. Check the voltage regularly to make sure that the regulator is working properly. The voltage for the regulator
is 14.2.1±0.2V.
8. Check the generator output voltage regularly. The voltage should be (14.2±0.25)V.
