Draining the engine oil (closed floor pan)
Compressor cooling oil and engine coolant drain lines are led to a central point outside the ma‐
chine with closed floor pan. They are located at the rear of the machine, in a recessed connection
box. The box can be accessed from below by removing a cover.
Oil is drained via a pipeline screwed into the engine block's drain point. The pipeline is closed with
a shut-off valve and secured with an additional plug.
