If the jobsite changes frequently and it is difficult to manage the density of the antifreeze, a density of up to 50%
can be permitted.
Super coolant is flammable, so be particularly careful to keep it away from flame.
Super coolant is toxic. When removing the drain plug, be careful not to get coolant on yourself.
If it gets into your eyes, wash your eyes immediately with ample water, then consult a doctor for treatment.
Always use Komatsu genuine super coolant (AF-NAC) for the coolant.
Use tap water to dilute the coolant. If river water or well water or simple water supply must be used, please consult
your Komatsu distributor.
We recommend the use of a super coolant density meter to control the mixing ratio.
