Old foreman told me to grease the boom pins every single day...
When I first started about 12 years ago I had this old foreman, Bill, who was super strict about greasing the boom pins every morning no matter what. I figured he was just being a grumpy old guy and I'd skip it sometimes to save time. Well, about 2 months in I bent a pin on a Liebherr LTM 1050 because I let it get dry and it seized up on a lift. Cost the company like 3 grand in parts and downtime and Bill just looked at me and said "told ya." Has anyone else had a mentor give them advice that seemed pointless but turned out to save their butt later?
