14.7.2Checking the coolant level and topping up the
coolant
CAUTION
Risk of burns on account of hot components
Do not open or touch the radiator or parts of the cooling
system while the motor is hot.
CAUTION
Risk of injury due to pressurised cooling system
Carefully open the expansion tank (2 levels).
ATTENTION
Material damage due to incorrect coolant
Top up the coolant only when the engine is cold.
The water/antifreeze mixing ratio should be 60:40 to 50:50.
This usually corresponds to frost protection from -25 °C to
-40 °C.
The minimum mixing ratio should be 70:30 and the maxi-
mum mixing ratio 40:60. Further increasing the proportion
of antifreeze (e.g. 30:70), does not further improve the
freezing point.
The mixture of the coolant shall consist of deionised or dis-
tilled water and of radiator protection according to stand-
ards ASTM D 3306 Type 1 monoethylene glycol-based
with addition of organic inhibitors.
For coolant, see chapter "Technical data".

1. Check the filling level when the engine is cold.
2. Open the right-hand service flap.
3. Check the filling level in the expansion reservoir.
Note
The correct coolant level must be between MAX and
MIN. In case of severe loss of coolant, carry out trouble-
shooting and correct any faults found.
4. Top up the coolant if necessary.
Add coolant
5. Turn the cap of the expansion tank to open and remove
it.
6. Add approved coolant to expansion tank to top marking
(MAX).
7. Fit the cap of the expansion tank and tighten.

1. A hydraulic oil level that is too low is shown on the dis-
play.
2. Top up the hydraulic oil if necessary.
Note
Lacking hydraulic oil can be topped up using a special
accessory tool connected to the leakage coupling on the
vehicle. If required, request the order no. at Kärcher or
have Kärcher Customer Service do the topping up.
For the hydraulic oil type: See chapter "Technical data".
