Need advice on first starting up old baler

I have a New Holland 269 wire-tie baler I just got.

I have never even been around a running baler!

Can I start it up and run it without any wire, just to get a feel for how it operates?

Would that do any harm to it?

 

Other than keeping away from moving parts, any burning advice while starting up an unknown baler for the 1st time?

 

Thanks much,

Dave in Emmett, ID (PS--anybody in or near Emmett that would be willing to come and advise?)
