Having a tool change is always nice

About reverted axis. Most of the machines in that style comes in straight line from horizontal machines but only have added a vertical head. Most of them even have horizontal spindle nose under head. That's why there are some machines that have horizontal axis setup. To be less technical - if your table goes UP / DOWN in Z axis = u have vertical setup. If your table goes UP / DOWN in Y axis = you have horizontal setup. Nothing wrong with that - just have to think twice what you do I'm used to vertical and sometimes i'm using my friends MAHO with horizontal setup = few times near crashed cause of inverted programming

About HH i'm not able to help you Only thing that i know about HH is that it exists

Easiest way to find coolant reservoir is to follow drain hose from table or table enclosure. It can be in the lower rear part of base or a stand alone box...

Does it have a tool magazine or you switch tools by hand? And does it have normal axis or reverted?

Very nice and rigid machine but has one minus as most of the older machines in same style than i don't like. Movement in Z axis is made by table. That's no problem if you're doing small things. Problem starts when you put 500kg or more of material at the table... Vertical screw and servo is having hard time than... Probably you could compensate that by counterweight but it would need to be adjusted every time you switch setup on table to match current weight...

Other than that one small issue they are very nice work horses

I've made a little change to your pics so it would be easier to discuss...



I don't own a TOS mill but some of the buttons are common for most of machines so:

1. Coolant ON/OFF
2. ...
3. ...
4. (Probably) Door switch override ON/OFF. You can or can't mill with door open.
5. (Probably) Spindle STOP.
6. Feed Hold - Works like PAUSE button but probably do not stop spindle so the button 5 is needed to put hands in machine
7. Cycle START.
8. (Probably) Rapid JOG. If you press "arrow button" the axis will move with feed speed. If you press and hold Button8 and arrow button the axis will move in RAPID MODE (faster).

Those are only my guess so anyone feel free to correct me or write down your own version
Including full machine photo and type number would help. Maybe someone has a manual for that...

Cheers mate...

PS (in Polish for other guys that maybe don't know English) :
