Maintenance
Hydraulics cooling system
The hydraulic oil radiator is located under the engine cover. It cools the hydraulic oil of the
drive and operating hydraulics.
Specific safety instructions
• Dirt on the radiator fins reduces the radiator’s cooling capacity! To avoid this:
☞ Clean the outside of the radiator at regular intervals. Refer to the maintenance plans
in the appendix for the cleaning intervals.
☞
In dusty or dirty work conditions, clean more frequently than indicated in the mainte-
nance plans.
• An insufficient coolant level (hydraulic oil) reduces the heat dissipation capacity as well
and can lead to engine damage! Therefore:
☞
Check the oil level at regular intervals. Refer to the maintenance plans in the appen-
dix for the intervals.
☞ If coolant must be added frequently, check the cooling system for leaks and/or con-
tact your dealer!
☞
Never add cold water/coolant if the engine is warm!
• The use of the wrong coolant can destroy the engine and the radiator. Therefore:
☞
Add enough antifreeze compound to the coolant – but never more than 50 %. If pos-
sible, use brand-name antifreeze agents since they already contain anti-corrosion
agents.
☞ Observe the coolant compound table
– see chapter 5.9 Fluids and lubricants on page 5-35
☞
Do not use radiator cleaning compounds if an antifreeze compound has been added
to the coolant – otherwise this causes sludge to form that can damage the engine.
Environment!
Use a suitable container to collect the fuel as it drains and dispose of it in an environmen-
tally friendly manner!
