Lubrication Points

For general lubrication points, see fuel, oil and fluid specification diagram.
If the tractor is to be used for work in a wet field, apply lubricant before use.

Lubricating Arm

To access the lubrication point, remove the rubber covers on the floor and instrument panel.
Refill lubricant with the supplied grease gun.

Hoses Check

Rubber parts, such as the fuel hose and radiator hose, age over time, even when the tractor is not in use.
Therefore, these parts must be replaced, including the cable ties, every two years or if damaged.
Warning:
If a hose is damaged, the fuel is leaking and a fire may occur. Make sure to check the hoses

and take the necessary measures if necessary.

Electric System Check

Battery Check and Charging

Danger:
When the battery is removed from the tractor and charged, hydrogen gas is released, which

poses a risk of fire. Charge the battery only in a well-ventilated area.
The battery produces highly flammable hydrogen gas, which can explode. Keep flammable and

combustible objects away from the battery.
The battery electrolyte is sulfuric acid and can burn your skin and eyes. Be careful not to spill

it.
Danger:
If the battery electrolyte gets in your eyes, on your skin, clothing, or an object, rinse the

affected areas thoroughly with water. If swallowed, drink plenty of water. If acid gets in your
eyes or is swallowed, see a doctor immediately.
Check
1. Check of the battery charge level
If the battery is not used for more than two weeks, it
can be difficult to start the engine. In this case,
recharge the battery.
2. If the battery terminal is corroded, it cannot supply
power. If it is corroded or dirty, treat it with
sandpaper or a brush.
