Like why we charge so much to repair problems. I guess it because of how we must disassembly things to get to problems. I had customers to watch me at times; unless, another tech and they wonder how can I be so fast at it and remember where everything goes. I had few customer to say oh they just re-assemble their equipment after the parts came in since was taking me longer than they like as I had others ahead of them to only realize they were way over their heads and let me complete the work. Nothing like handing the customer their handheld in a box disassembled.Thanks. I will certainly use the file. I've learned more in the past two weeks chasing this problem around than I have in the 17 years of owning this blower.
