Emptying the leak chamber
1
Slowly remove the screw plug (L) from the leak chamber and drain the collected fluid.
2
Clean the screw plug (L), fit with a new sealing ring and screw it in again.
Changing the coolant
The coolant should only be changed when the motor is cold. If the motor is still warm or hot, an
incorrect filling level is displayed, as the coolant expands under heat.
1
Unscrew the filling plug (K+).
2
Unscrew the drain plug (K-). Drain the coolant and collect it in a suitable reservoir. For com-
plete drainage, the machine must be slightly tipped on to its side.
Make sure that the machine cannot fall and/or slip away.
3
Clean the drain plug (K-), fit it with a new seal and screw it in again.
4
Fill coolant using the opening in the filling plug (K+). Comply with the specified lubricants
and filling quantities.
In order to permanently guarantee frost and corrosion protection, the
manufacturer's filling P35 must be used for topping up.
5
Clean the filling plug (K+), fit with a new sealing ring and screw it in again.
