WARNING
 Coolant is toxic. When you open the drain valve, make sure
you do not get any coolant on your body. If it gets into your
eyes, rinse your eyes with a large volume of fresh water and
seek medical assistance immediately.
 Please contact your Komatsu distributor when you are chang-
ing the coolant or processing the cooling water containing
coolant which has been drained in the course of repairing the
radiator; alternatively, have this work done by a specialist
company. Coolant is toxic. Do not let it flow away in drainage
channels, and do not sprinkle it on the ground either.
The amine-free engine coolant (AF-NAC) is already diluted with
distilled water, which makes it nonflammable.
Check the density using a coolant tester.
Place a container ready to collect the drained coolant; the volume
of the container should be larger than the specified volume of
coolant.
Prepare a hose for filling the coolant with.
