I never quite understood how one of the big box hardware stores could "chain" or "wire" the key to the machine. In my Operator Training classes (based upon the OEM program) I advised my students that the key had to be REMOVED when the trained operator left the equipment. Any Jack*ss could get on the lift and crash into a rack injuring or possibly killing someone. When I asked my higher-ups for an explanation I just got an "I dunno." Seems strange to me as these folks get their lifts on a national account basis through the manufacturer who produced the Operator Training Program I taught. Apparently the rules do not apply to everyone. There is nothing to keep a customer from jumping on a lift truck (or reach) and taking off. I know, I have. Perhaps they are in the process of using the password system but for now I feel they are leaving themselves wide open for some liability. As far as people taking keys home there are other measures that can be taken. For instance, mechanics who hold onto all of their paperwork and delay parts and service personell tend to get it turned in when they want their paycheck.
