Maintenance and Care
5.7.1 Cleaning the radiator
Check the radiator (Fig. 25/1) daily and
clean as necessary. Dirt on the radiator
ribs reduces the cooling capacity.
The radiator ribs are very thin
and can be easily damaged!
1. Open the seat console, refer to Sec-
tion 5.4.
2. Clean the radiator ribs with com-
pressed air, blowing from the engine
side outwards.
5.7.2 Refilling the coolant
Too little coolant reduces the cooling
capacity. Check the coolant level daily
through the cap and refill as necessary.
Only use the coolant prescri-
bed, refer to Technical Data.
Do not mix with other types!
Before the winter season be-
gins, check the concentration
of the coolant.
1. When the engine has cooled down,
open the cap (Fig. 25/2) carefully.
2. Check the coolant level. The optimal
coolant level is achieved when the
ribs are covered. Fill slowly. if neces-
sary.

4. Allow the engine to run for a few mi-
nutes.
5. Turn the engine off and allow to cool
down.
6. Check the coolant level again and
refill, if necessary.
Only refill coolant in the radia-
tor. Do not refill at the resuction
tank (Fig. 25/5)!
5.7.3 Changing the coolant
The coolant must be changed
every 1000 operating hours at
the latest.
1. Place a suitable collecting vessel un-
der the radiator draining hose (Fig.
25/4).
2. Open the draining hose and drain off
the coolant fully.
Coolant quantity, approx. 3 liters.
Dispose of the used coolant
according to the applicable en-
vironmental regulations!
3. Close the draining hose again.
4. Refill fresh coolant, refer to Techni-
cal Data.
5. Replace the cap.
6. Allow the engine to run for a few mi-
nutes.
7. Turn the engine off and allow to cool
