When deciding the ratio of antifreeze to water, check the lowest ;
temperature in the past, and decide from the mixing rate table given
below.
It is actually better to estimate a temperature about 10
deciding the mixing rate.

Antifreeze is flammable, so keep it away from any flame.
•
Use city water for the cooling water.
If river water, well water or other such water supply must be used,
contact your Komatsu distributor.
•
We recommend use of an antifreeze density gauge to control the
mixing proportions.
When removing drain plug, avoid pouring coolant on yourself.
