7 Maintenance
Checking the coolant level
Temperature indicator B (with acoustic warning) in the digital display on
the indicating instrument monitors the cooling system.
The coolant temperature should be between 80 and 105°C (176 and
221°F). If the engine coolant temperature rises above 110°C (230°F), the
control lamp 75 illuminates and a warning sounds.
If the coolant level drops below minimum, indicator light 74
illuminates and
a warning sounds.
Risk of engine damage due to overheating.
► Let the engine run at idling speed for a short time until the control
lamp 75 and the buzzer go out.
► Stop the engine and check the coolant level.
► Clean the radiator fins.
1. Park the machine on level ground.
2. Lower the loader unit.
3. Stop the engine and remove the starting key.
4. Apply the parking brake.
5. Open the engine cover.
6. Check the coolant level in the transparent reservoir A.
7. If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark – see “Adding coolant” on page 7-37.
Maintenance intervals – see “Maintenance plan” on page 7-3.
Specifications and fill quantities – see “Fluids and lubricants” on
page 7-12.
Check the coolant level before starting the engine.
Check the antifreeze at temperatures below 4 °C (39 °F).
Check the antifreeze with suitable testing equipment (antifreeze tester)
before the winter – see “Fluids and lubricants” on page 7-12.
