Draining liquid accumulation within the machine
The so-called "closed floor pan" contributes to the protection of the environment by preventing a
contamination of the soil in the event of leaking operating fluids.
Liquid accumulations within the machine's body can also cause corrosion or electrical faults.
Liquid accumulations must be removed as quickly as possible in order to avoid potential machine
faults.
For draining the liquid, maintenance openings have been added to the floor panel of the machine
which are closed with bungs.
