BATTERY 0.
WARNING
! The battery generates flammable gas, so 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 large amounts
of water, and consult a doctor.
! Battery electrolyte dissolves paint. If it gets on to 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.
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%, and insulate it
against cold temperature so that the machine can be started easily the next morning.
REMARK
Measure the specific gravity and calculate the rate of charge from the following conversion table.
! As the battery capacity drops markedly in low temperatures, cover the battery or remove it from the machine,
keep it in a warm place, and install it again the next morning.
! If the electrolyte level is low, add distilled water in the morning before beginning work. Do not add the water
after the day‘s work so as to prevent fluid in the battery from freezing in the night.
PRECAUTIONS AFTER COMPLETION OF WORK 0.
To prevent mud, water, or the undercarriage from freezing and making it impossible for the machine to move on
the following morning, always 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 frozen 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.
AFTER COLD WEATHER 0.
When season changes and the weather becomes warmer, do as follows.
! Replace the fuel and oil for all parts with oil of the viscosity specified.
For details, see “LUBRICANTS AND OPERATING MEANS ( 4-8 )“.
! If for any reason permanent antifreeze cannot be used, and an ethyl glycol base antifreeze (winter, one season
type) is used instead, or if no antifreeze is used, drain the cooling system completely, then clean out the inside
of the cooling system thoroughly, and fill with fresh soft water.
