The working position is a bit unfortunate and actually you should have to drained and clean the oil tank bevore, but none of this is a problem for a dragon... (hopefully he won't slip his tail on the oily bracket, otherwise it will take again so long to clean the work clothes and there will be sure again trouble because he has contaminated the oil and he has also eat too much of it (again) before his colleagues can finally convince him to come out...)
