Environment
Possible environmental damage.
► Avoid releasing antifreeze and coolant.
► Collect antifreeze and coolant, and dispose of them in an
environmentally friendly manner.
Information
Adapt the water/coolant mixture to local conditions and to the work site of
the machine – see "Coolant" on page E-8.
Checking/adding/changing coolant
Check the coolant level regularly. The coolant must be visible from above
in the radiator opening.
Ensure that enough antifreeze is mixed into the coolant during the
summer, because antifreeze also helps protect the cooler from internal
corrosion.
Preparations
1. Park the machine on firm, level and dry ground.
2. Apply the parking brake.
3. Fully retract the loader unit and lower it to the ground.
4. Stop the engine.
5. Wait one minute.
6. Open the engine cover.
Checking the coolant level
Open coolant filler inlet E:
1. Press the cover down.
2. Turn the cover clockwise.
3. Remove the cover.
➥ The coolant must be visible from above in the radiator opening.
Adding coolant
If no coolant can be seen in the coolant filler inlet, add coolant until it can
be seen in the inlet. Then close the inlet.
Draining coolant
1. Set the heating temperature controller to maximum temperature in
order to drain the coolant from the heating circuit as well.
2. Remove the base plate – see "Removing/installing the base plate" on
page 10-2.
3. Place a container to collect the fuel.
4. Drain the coolant. To do this, disassemble the cooling water hose 2 .
5. When only a small amount of fluid flows out, also open the filler inlet.
6. Reassemble the cooling water hose.
7. Add coolant slowly up to the “MAX” mark.
8. Close the coolant filler inlet.
9. Open the heating circuit fully.
