Komatsu D41s manuals and oils

Can anyone suggest a source of a workshop manual for a D41s, and can anybody give any info on the recommended lubricants? My normal supplier is listing monograde engine oil for every part of the transmission and hydraulic system which seems an unlikely choice to me.

I've lubricants table for D41P-3, should be the same with D41S-3. Monograde engine oil looks like OK.

Thanks for that, reassuring to see it from a manual.
I've looked on the websites for a couple of other oil suppliers who also seem to be showing monograde engine oil for this purpose, I find it strange as normally stuff I work on wants dedicated transmission lube, dedicated hydraulic lube or one that can do both of those but not engine oil. Especially when wet brakes and clutches are concerned.
Anyway, I'm sure Komatsu know what they're doing.

You're welcome.
