Whereabouts on the machine is the yellow box with the reset switch ?
That may be what has tripped on my 351s model at the weekend, but haven't got any yellow box or similar as far as I recall so not sure where a reset would be !
Once you've got your machine sorted I'm sure you'll be pleased, they are great workhorses.
Must have cut up tons of logs on my mine for planking and turning blanks in the last few years and no problems till the weekend !
