Dear Mr. Jones,
We are having problems with the new machine that you installed for us last month.
Every time we run the machine for more than three hours it overheats. We tried our best to fix it following the instructions in your manual but there is no improvement. What would you advise us to do?
I look forward to hearing from you.
