Even then I would suggest at least a short course in operation of the
Cherry Picker/Hydraulic platform.
Those have been rolled over, stuck into power lines, and just moved in
the wrong direction at the wrong time.
ALWAYS use the outriggers! There was a link to a news story just in the
past couple of weeks where a worker was killed using one.
I have to admit I do not like using the hydraulic platforms and
particularly the tall ones. I feel like I'm balanced on the top end of
a wet noodle. They impart a very unsteady feeling to me on flat concrete
let alone on dirt.
73 and good luck,
Roger (K8RI)
