BATTERY
WARNING
The battery generates flammable gas. Do not bring fire or sparks near the battery.
Battery electrolyte is dangerous. If it gets in your eyes or on your skin, wash it off with a large amount of water and consult a
doctor.
Battery electrolyte dissolves paint. If it gets on the bodywork, wash it off immediately with water.
If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source. There is danger
that the battery may explode.
Battery electrolyte is toxic. Do not let it flow into drainage ditches or spray it on to the ground surface.
When the ambient temperature drops, the capacity of the battery will also drop. If the battery charge ratio is low, the
battery electrolyte may freeze. Maintain the battery charge as close as possible to 100%. Insulate it against cold
temperature to ensure the machine can be started easily the next morning.
Measure the specific gravity and calculate the rate of charge from the following conversion table.

When adding distilled water in cold weather, add it before starting operations in the morning to prevent the
electrolyte from freezing.
CAUTIONS AFTER COMPLETION OF WORK
To prevent mud, water, or the undercarriage from freezing and making it impossible for the machine to move on the
following morning, observe the following precautions.
Mud and water on the machine body should be completely removed.
This is to prevent damage to the seal caused by mud or dirt getting inside the seal with drops of water.
Park the machine on hard, dry ground.
If this is impossible, park the machine on wooden boards.
The boards help protect the tracks from being frozen in soil and the machine can start next morning.
Open the drain valve and drain any water collected in the fuel system to prevent it from freezing.
As the battery capacity drastically drops in low temperatures, cover or remove the battery from the machine, store
the battery in a warm place, and install it the next morning.
AFTER COLD WEATHER
When the season changes and the weather becomes warmer, do as follows.
Replace the fuel and oil for all parts with oil of the viscosity specified.
