I looked this machine up online and it appears to be an industrial machine, with a separate 'head' and motor. This type of industrial set up is mounted in a heavy table, with the large motor hung on the back of the table. You turn the motor on first, from a switch on the table. These usually have a large oil reservoir underneath the table which wicks oil up into the machine. There is a bubble on the top of the machine that shows you the oil level.
I used to work commercially with these type machines and can't see any way it could be set up to work in a long arm frame.
