Specific safety instructions

The combined oil/water cooler is located in the engine compartment, on the right side of
the engine. It cools the diesel engine, and the hydraulic oil of the drive and work
hydraulics.
The expansion tank for the coolant is also located in the engine compartment, above the
cooler.
•
Dirt on the cooling fins reduces the cooler's heat rejection capacity!
To avoid this:
• Clean the outside of the cooler at regular intervals. Refer to the maintenance plans in
the Annex for the cleaning intervals
• In dusty or dirty work conditions, clean more frequently than indicated in the mainte-
nance plans
•
An insufficient coolant level reduces the heat rejection capacity as well, and can lead to
engine damage! Therefore:
• Check the coolant level at regular intervals. Refer to the maintenance plan in the
Annex for the intervals
• If coolant must be added frequently, check the cooling system for leakages and/or
contact your dealer!
• Never fill in cold water/coolant if the engine is warm!
• After filling the expansion tank, conduct a test run with the engine and check the
coolant level again after switching off the engine
•
The use of the wrong coolant can destroy the engine and the cooler. Therefore:
• Add sufficient antifreeze to the coolant – but never more than 50%. If possible use
brand-name antifreeze that have anticorrosion additives
• Observe the coolant table in section "Specifications"
• Do not use cooler cleaning compounds if antifreeze has been added to the coolant –
otherwise this causes sludge to form, which can damage the engine
Environment!
Use a suitable container to collect the coolant as it drains and dispose of it in an environ-
mentally friendly manner!
