I just purchased a used FMF-040 fork lift. From my research here and elsewhere it seems to be a Baker or rebadged Linde. Serial starts with 0 (oh).

There seems to be quite a few free resources (manuals, parts lists) for other models FJF.

Questions:
1) What does the lever/brake do on the floor to the right of the seat?
2) Is there a service manual for the FMF-040? Or is it the same as other models?
3) What is the max lift capacity? And does it decrease as the load rises?
4) What is the gross weight?

Thanks!
