I worked with a guy that had a son who owned a rental business.
I had heard him complain about how the customers kept damaging the wood splitters, many times .
He asked me to have a look at the splitters, and recommend anything that could help the splitters survive.
I went to see them one Saturday.,, three looked ready for the scrap pile, three had just been purchased.
These were WAY overbuilt units, that should have survived a nuclear blast!!
He then told me the three that were in such bad shape were only 9 months old!!
After thinking about it a little, I asked for a couple hand tools,,
I reduced the relief valve pressure one full turn on each of the new splitters.
He was concerned that the customers would complain about the lower pressure,
I told him
"NA, they will never know, if they do complain, blame it on the wood they are splitting."
About a year later (after I had forgot about the splitters) he came by one day, and laid three $100 bills on my desk.
He said what I had done was AMAZING!! The splitters, other than a little paint missing, still almost looked like new!!
AND, they never had one complaint.
He told me how happy his son was,, and wanted me to look at the other stuff they rented.
I laughed, and said that I could not perform miracles
EVERY day!! LOL!!
