Visual inspection
• Check the excavator for visible damage and leaks.
Check the engine oil level
• Pull out the oil dipstick (1) and wipe it with a clean cloth.
• Insert the oil dipstick completely and pull it out again. The
oil level should be in the "A" area. If the oil level is too low,
add engine oil (page 99).
When the oil level is too high or too low, the engine
might get damaged during operation.
Checking the coolant level
• Check the coolant level in the expansion reservoir (1). The
fluid level must be between FULL and LOW.
Do not open the radiator cap.
If the coolant level is below the LOW mark, refill
(page 96).
If the coolant level is below the LOW mark a short time after adding coolant, the cooling system
is leaky. The excavator must only be started again after the fault is repaired.
Checking the radiator and the oil cooler
• Check the radiator (2) and oil cooler (1) for leaks and debris
(e.g. leaves).
• If there are leaves or other debris between the radiator and
cooler, clean the radiator (page 97).
