Gray market Airman ax40

So I know I shouldn’t have... but the price was great so I picked up a really clean Airman AX40ur-5.
Now I’m searching around for a service manual (it’s not broken, just want to prepare and do maintenance) and am totally striking out... which is to be expected I guess.
I was hoping someone here had some info or a direction for me to look in to find info on this thing?

What fluids to use? Capacities? Any info at all would be great...

Looks to be a rebranded Hitachi ZX40UR-2???

That’s what I’m kinda thinking but not sure... do I just go with a service manual for the hitachi? It has a yanmar engine.

It's the other way around, Hitachi Deere are rebranded airman machines in the minis I was told.

Off their website

"1991 Began to sell new mini-excavator AX series which was jointly developed with Hitachi Construction Machinery. Created a new sensation with original color of purple into construction industry which orange color is popular."

So I guess they are basically one and the same?

It looks very similar to the Deere and hitachi... however, mine is the dash 5 model with a swing boom and there is no info that I’ve been able to find. Seems like it doesn’t exist( online at least) but there is info up to dash 4 models.
That’s the risk in gray market

Also, looks like I have a warning light on... red “sys” light.
I’ll make a separate post for that.
