COLD WEATHER OPERATION

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 to fuel and oil with low viscosity for all components. For details of the specified viscosity, see
"LUBRICANTS, FUEL AND COOLANT SPECIFICATIONS (PAGE 4-9)".
Cooling System Coolant
Antifreeze 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 at once.
When changing the coolant or when handling coolant containing antifreeze that has been drained when repairing the radiator,
please contact your Komatsu distributor or request a specialist company to carry out the operation. Antifreeze is toxic. Do not
let it flow into drainage ditches or spray it onto the ground surface.
Antifreeze is flammable. Do not bring any flame close. Do not smoke when handling antifreeze.
NOTICE
Never use methanol, ethanol, or propanol-based antifreeze.
Never use any water-leakage prevention agent or any antifreeze containing such an agent.
Do not mix different types of antifreeze.
For details of the antifreeze mixture when changing the coolant, see "CLEAN INSIDE OF COOLING SYSTEM
(PAGE 4-20)".
Use a Permanent Antifreeze (ethylene glycol mixed with corrosion inhibitor, antifoam agent, etc.) meeting the
standard requirements as shown below. With permanent antifreeze, no change of coolant is required for a year. If
it is doubtful that an available antifreeze meets the standard requirements, ask the supplier of that antifreeze for
information.
Standard requirements for permanent antifreeze
SAE J1034
FEDERAL STANDARD O-A-548D
REMARK
In areas where permanent antifreeze is not available, it is possible to use antifreeze whose main component is
ethylene glycol and does not contain any corrosion inhibitor. (Such antifreeze can be used for the winter season
only.) However, in such a case, the coolant must be changed twice a year (spring and autumn), so use permanent
antifreeze when possible.
