I have been a long time LHR Suporter... Sure... Machines do BREAK down... and Sure.... Sometimes Operators make mistakes, and in MY opinion if you keep up with the maintenance you will love the machine.
The more "Hands On" you are the better you will like it....
The more spare parts you decide to stock the less down time you will have.... You will find that things like Carbon Brushes for the Cut Motor, Sand Paper Belts, FSC Cable and the 685ZZ X Gearbox Bearings are "Consumables" and must be treated as such and have them in stock and follow a Scheduled Replacement Recommendation.
