MAINTENANCE BASICS
7-8
COOLANTS
• Always prepare coolants as described in the maintenance
instructions.
• River water contains large amounts of calcium and other
substances. If you use river water, scale will deposit in both
the engine and the radiator, impairing heat exchange, which
may lead to overheating.
• Only use drinking water.
• Always adhere to the information given in the operating and
maintenance instructions when using antifreeze.
• Our machines are delivered with original Komatsu anti-
freeze. This antifreeze does, among other things, protect
against corrosion in the cooling system, it lubricates moving
parts, and it increases the coolant's boiling point. For this
reason, it must also be used when working in hot working ar-
eas.
• Antifreeze is highly inflammable. For this reason, take care
that antifreeze does not come into contact with naked light.
• If the coolant level is too low, the air in the cooling system
may lead to overheating and corrosion in the cooling sys-
tem.
• If the engine is overheated and you have to top off coolant,
allow the engine to cool down before you fill in the coolant.
WINDSCREEN WASHER LIQUID
Only use clean windscreen washer liquid approved for use in au-
tomobiles.
