Safety instructions –
Cooling system
Danger
•
The cooling system is under pressure. If the cooling system cap is opened with a hot engine there
is a risk of scalding. Allow the engine to cool down.
•
Wait at least 10 minutes after switching off the engine.
•
Wear protective gloves and clothing.
•
Always start by actuating the safety valve in the expansion tank filler cap; to do this, open the
filler cap to the first notch and allow the pressure to escape.
•
Risk of injury to limbs or of hair or clothing getting caught up in rotating parts. Switch the engine off
and pull out the ignition key. There is a risk of injury!
•
Never switch on the reversing fan (option) in the vicinity of people or in road traffic. Make sure
there are no persons or vehicles in the direct vicinity of the vehicle. Only switch on the reversing
fan in open spaces. There is a risk of accidents!
Attention
•
Small air bubbles can form when the radiator is filled. Therefore the cooling system must be
vented at the same time. Have this done by an authorised workshop!
•
Be careful when cleaning the radiator with a high-pressure cleaner or steam jet. The radiator fins
are made of 0.1-mm-thick sheet metal and can be easily damaged. Make sure that the nozzle is
not closer than 30 cm to the radiator fins.
•
The coolant additive and the coolant are detrimental to health. Therefore, store the coolant
additive in the original container and take particular care to ensure that it is kept out of the reach of
children.
•
Dirt on the radiator fins reduces the radiator’s heat dissipation capacity. Therefore:
•
Clean the outside of the radiator at regular intervals.
•
In dusty or dirty working conditions, clean more frequently than indicated in the maintenance
plans.
•
An insufficient coolant level reduces the heat dissipation capacity as well, and can lead to engine
damage. Therefore:
•
Check the cooling level at regular intervals, see maintenance plan.
•
If coolant must be added frequently, check the cooling system for leaks and/or seek advice from
your authorised workshop.
•
Never fill up with cold water/coolant if the engine is warm.
•
After filling the radiator, test-run the engine and check the coolant level again after switching off
the engine.
•
Using the wrong coolant can destroy the engine and radiator. Therefore:
•
Coolant specification, see Engine/vehicle fluids and lubricants.
•
Do not use radiator cleaning agents if an antifreeze compound has been added to the coolant,
as this causes sludge to form, which can damage the engine.
Environmental danger
•
Ensure safe and environment-conserving disposal of operating and auxiliary materials.
Take up escaping or spilled operating materials in suitable containers and dispose of them in an
environmentally friendly manner.
