has been released by opening the filler plug (2)
one turn.
2. Wait a few minutes until the oil level is constant
(oil level gauge (1)).

upper part of the green area.
4. Reinstall and tighten the filler plug (2).
COOLANT SPECIFICATIONS
The use of the correct coolant is important for good
heat transfer and protection of liquid-cooled engines.
Coolants used in these engines must be mixtures of
good quality water (distilled or de-ionised), special
coolant additives and if necessary freeze protection.
Coolant that is not to manufacturer's specification will
result in mechanical damage of the engine.
The freezing point of the coolant must be lower than
the freezing point that can occur in the area. The
difference must be at least 5°C (9°F). If the coolant
freezes, it may crack the cylinder block, radiator or
coolant pump.
Consult the engine's operation manual and follow the
manufacturer's directions.

It is strongly recommended to use Atlas
Copco branded coolant.
Never mix different coolants and mix the
coolant components outside the cooling
system.
