WARNING
q
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.
q
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.
q
Antifreeze is flammable. Do not bring any flame close. Do not smoke when handling antifreeze.
NOTICE
q
Use Komatsu Supercoolant wherever available, or use permanent type antifreeze coolant.
q
Never use methanol, ethanol, or propanol-based antifreeze.
q
Do not use any water leakage prevention agent, either alone, or in combination with antifreeze.
q
Do not mix one brand of antifreeze with a different brand.
For details on the amount of antifreeze mixture and on when to change the coolant, see “CLEAN INSIDE OF
COOLING SYSTEM (4-21)“.
