Cleaning the excavator
Before cleaning, shut down the engine and secure it against starting.
If a steam cleaner is used for cleaning the excavator, do not direct the steam jet at electric com-
ponents.
Do not direct a water jet into the intake opening of the air filter.
Do not clean the excavator with inflammable liquids.
The excavator may only be washed at suitable places (using oil and grease separators).
The excavator can be cleaned with water and a commercial cleaning agent. Make sure no water gets into the
electrical system.
Use a plastic cleaner for plastic parts.
Before cleaning, make sure to tape the air inlet for the air conditioner and heater system at the swivel frame.
Maintenance
Adhere to the instructions for regular servicing to keep the excavator in good condition.
Refilling the coolant
•
Check the antifreeze content with an antifreeze tester that is
qualified for -25
°
C.
The antifreeze portion of the coolant should not
exceed 45%.
•
Open the engine compartment cover (page 82).
•
Open the coolant expansion reservoir cap while the engine
is cold and fill pre-mixed coolant up to the FULL mark (1).
If the coolant expansion reservoir was completely empty, check the coolant level in the radiator.
For checking the fluid level of the radiator, remove the side panel (page 83).
