Quick Question for Operators

1.First, what is your name and company, and what kind of business do you run?
2.Do you have a dedicated technician? If so, what do their day-to-day responsibilities look like? If not, how do you handle that?
3.How do you increase the skillset of yourself or your technicians? (Betson Technical University, other seminars at state association meetings, etc.)
4.Do you face parts supply issues? For example, are parts readily available (and quick to arrive) from either the manufacturer or other suppliers? Do you stock key parts in-house?
