COLD WEATHER OPERATION INFORMATION

If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as
follows.
FUEL AND LUBRICANTS
Change fuel and oil with ones of low viscosity for all components.
For the details of specified viscosity, see "RECOMMENDED FUEL, COOLANT, AND LUBRICANT (7-5)".
COOLANT
• 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 amounts of fresh water and see a doctor immediately.
• When handling the cooling water containing coolant that has been drained during changing the
coolant or repair of radiator, contact your Komatsu distributor or request a qualified company to
perform the operation. Coolant is toxic, so never pour it into drainage ditches or drain it onto the
ground surface.
NOTICE
Komatsu recommends using genuine Non-Amine Engine Coolant (AF-NAC) for the coolant.
Non-Amine Engine Coolant (AF-NAC) is already diluted with distilled water, so it is not flammable.
For details on the coolant change interval and the density of Non-Amine Engine Coolant (AF-NAC), see "METH-
OD FOR CLEANING INSIDE OF COOLING SYSTEM (4-18)".
BATTERY
• The battery generates flammable gas. Do not bring any open flame near the battery.
• Battery electrolyte is dangerous object. If it should get into your eyes or on your skin, wash it off
with large amounts of fresh water and see a doctor immediately.
• 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 pow-
er 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 sur-
face.
When the ambient temperature drops, the capacity of the battery will also drop. If the battery charging rate is
low, the battery electrolyte may freeze. Maintain the battery charging rate as close as possible to 100%. Insulate
it against cold temperature to ensure the machine can be started easily the next morning.
REMARK
When it is possible to check the electrolyte, measure the gravity of the electrolyte and calculate the charging
rate from the following conversion table.
