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.
STOP
If the coolant level is below the LOW mark, refill cool-
ant (page 124).
If the coolant level is below the LOW mark a short time after adding coolant, the cooling system is
leaky. The excavator may only be started again after the fault is repaired.
Checking coolant radiator and oil cooler
Walk-around inspection of coolant radiator (1) and oil cooler (2)
!
for tightness and soiling.
If there is any dirt etc on the radiators, clean the radiators
!
(page 125).
Checking of the V-belt
The engine must be switched off and the key removed!
STOP
Do not attempt to grasp rotating or moving parts.
Press in the V-belt (1) at position "A". The V-belt must give way
!
for approx. 8 mm (pressure: 10 kg). Adjust the V-belts if neces-
sary (page 126).
Check condition of the V-belt, it must not have any cracks or
!
other damage. Replace the V-belts if necessary (page 126).
Checking the exhaust system for leaks
Check the exhaust system for leaks and security (formation of cracks).
!
If the inspection is carried out when the engine is warm, there is a risk of burns at the exhaust system.
STOP
If the exhaust system is leaky or loose, the excavator may only be taken into operation after the defects are
!
eliminated.
