Gents, would someone here have a digital copy of the maintenance manual for an SN 40A machine?

Primarily I want to change all the fluids, and would like to know what kind of lubrication, where and how much to put in.
Apparently all the level sights were broken/cracked in a previous life, and all of them were "repaired" by filling the clear plastic window with silicone.

The lathe is functioning fine, but there is a little elevated noise from the gearbox.
Nothing major, and it does not sound like a broken gear, rather bearing noise due to low oil levels.

Found 3 oil fill ports, but there are like 5 level sights....

Thank You

Afaik there is no manual in English, any way note the this lathe have pump in reservoir at the back and that it's turns "unconventional", i.e. handle down the chuck turns toward you, unlike most lathes, if you reverse the motor the pump will not work (the site on the headstock get filled from the pump)
 
good find. unfortunatly the pictures (no. 5 for lubication) are missing from the document. it seems the gearbox and the main bearings get oil from one pump. the threading gears get oil from another pump.
 
Thank You!!

So handle down = Spindle FWD is the proper phasing for the motor.

Still, there are images for an English manual, just no manual itself...
