We want to help you check and fill your Yanmar tractor battery. 

If you do not feel that you understand these steps, or can perform them safely, consult your tractor dealer, owner's manual, or local mechanic. 

Time to get started.

Explosion Hazard:  

  • Never check the remaining battery charge by shorting out the terminals.  This will result in a spark and may cause an explosion or fire.  Use a hydrometer to check the remaining battery charge.
  • If the electrolyte is frozen, slowly warm the battery before you recharge it.
  • Failure to comply will result in death or serious injury.

Burn Hazard:

  • Batteries contain sulfuric acid.  Never allow battery fluid to come in contact with clothing, skin or eyes.  Severe burns could result.  Always wear safety goggles and protective clothing when servicing the battery.  If battery fluid contacts the eyes and/or skin, immediately flush the affected area with a large amount of clean water and obtain prompt medical treatment.
  • Failure to comply could result in death or serious injury.

Environmental Notice:

  • Always be environmentally responsible.
  • Follow the guidelines of the EPA or other governmental agencies for the proper disposal of hazardous materials such as engine oil, diesel fuel and engine coolant.
  • Consult the local authorities or reclamation facility.
  • Never dispose of hazardous materials irresponsibly by dumping them into a sewer, on the ground, or into ground water or waterways.
  • Failure to follow these procedures may seriously harm the environment.

 Adding Battery Fluid:

  • When the amount of fluid nears the lower limit (Figure 5-7, (3)), fill with distilled water (Figure 5-7, (2)) so it is at the upper limit (Figure 5-7, (1)).  If operation continues with insufficient battery fluid, the battery life is shortened, and the battery may overheat and explode.  During the summer, check the fluid level more often than specified.

 

  • If the engine cranking speed is so slow that the engine does not start, recharge the battery.  If the engine still will not start after charging, have your authorized YANMAR industrial engine dealer or distributor check the battery and the engine's starting system.
  • If operating the machine where the ambient temperature could drop to 5 °F (-15 °C) or less, remove the battery from the machine at the end of the day.  Store the battery in a warm place until the next use.  This will help start the engine easily at low ambient temperatures.
