In Australia companies are quite stringent in regards to user error. Repairers will not approve warranty repairs if a tool is burnt out due to incorrect use, intentional or not. The onus is on the user to know the limitations of their tool. Personally I think the 5 year period offered by Milwaukee is a good marketing tactic and not much else. They would be well aware that if there is a manufacturing defect it is most likely going to occur within the first 12 months.
