ing circuit
Burns due to hot fluids and sur-
faces
• At operating temperature, the
engine cooling system is hot and
pressurized.
• Avoid touching coolant or parts
carrying coolant. There is a risk of
burns.
• Only check the coolant level once
the cap has cooled down enough
for you to hold it. Then turn the
cover carefully first to discharge
the excess pressure.
In an emergency: Administer first
aid, seek treatment from a doctor
â–º
Check the diesel engine, fan and cooler for

If the coolant level is too low, the indicator
(162/38) will light up.
â–º
Unscrew the protective cover (161/1).
â–º

â–º
After filling the cooling system, let the die-
sel engine run for a while with the heating
turned on. Then check the coolant level
again.
â–º
When the machine is delivered, the coolant
contains antifreeze protection to -35°C
(corresponding to a mixture of about 45%
antifreeze).
Antifreeze should be added throughout the
year every time the system is topped up.
