COLD WEATHER OPERATION INFORMATION:ALL-0000-265K01A
If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as fol-
lows.
FUEL AND LUBRICANTS
Fuel and Lubricants:ALL-RA19-265K00A
Change to fuel and oil with low viscosity for all components.
For the details of specified viscosity, see "RECOMMENDED FUEL, COOLANT, AND LUBRICANT (7-4)".

WARNING
q
Coolant is toxic. Be careful not to get it into your eyes or on your skin. If it should get into your eyes or
on your skin, wash it off with large amount of fresh water and see a doctor immediately.
q
When changing the coolant or draining the coolant from the radiator during repairs, ask a qualified
person to handle any coolant containing antifreeze, or contact your Komatsu distributor. Coolant is
toxic, so never pour it into ditches or drain it onto the ground surface.
NOTICE
Komatsu recommends using Non-Amine Engine Coolant (AF-NAC) for the coolant.
The Non-Amine Engine Coolant (AF-NAC) is already diluted with distilled water, so it is not flammable.
For details of the density of the Non-Amine Engine Coolant (AF-NAC) and the interval for changing the coolant,
see "CLEAN INSIDE OF COOLING SYSTEM (4-17)".
If the ambient temperature is expected to drop below 0° C, change fuel and oil to low viscosity type for all compo-
nents. For detail see RECOMMENDED FUEL, COOLANT, AND LUBRICANT (7-4).
BATTERY
Battery:ALL-AW10-265K00A
k
WARNING
q
The battery generates flammable gas. Do not bring fire or sparks near the battery.
q
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.
q
Battery electrolyte dissolves paint.If it gets on the bodywork, wash it off immediately with water.
q
If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power
source.There is a danger that the battery may explode.
q
Battery electrolyte is toxic. Do not let it flow into 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 ratio as close as possible to 100%. Insulate it
against cold temperature to ensure the machine can be started easily on the next morning.
REMARK
Measure the specific gravity and calculate the charging rate from the following conversion table.
q
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 again the next morning.
q
If the electrolyte level is low, add distilled water in the morning before beginning work. Do not add water after
the day's work to prevent diluted electrolyte in the battery from freezing during the night.
