Are there any instructions or videos on how to service this diesel? The manual suggests to take it to an authorized service center but there are none available. I don't know if the power train needs lubrication or the traction tires I tried to change are the problem, but it runs wobbly and noisy. Any help appreciated. I have in the past serviced post war diesels but am not sure if this is one that should not be touched by the uninitiated.
