    Greg - as you deduced, it is the reel that has gone dead and therefore must have a little breaker inside - so hopefully the motor on the saw will still be fine - thank you! The sooner I get power to the shed the better - in the meantime, do you think it OK to run a single 15A extension cord to the back shed (about 15 metres) to run the saw? I know that some often say this is unadvisable due to power drop etc. but I don't see what the difference would be if one were to run underground cable as the electrician would do (and that I would dig) - in any case I will eventually do this - thanks again; LC

    I'm glad that it was something so simple. On the reel cord, check for a tiny little button in the reel-that will be the breaker. You can re-set it for future use with lower power stuff.

    I'd cheerfully run a 15A cord that long. You can google the voltage drop for different wire sizes. if its 2.5mm you'd probably be suffering less than a 4 volt drop (I don't know your motor load or wire size or I'd do the math)

    This is a old thread but I had to put my 2¢ in, a Unisaw has a proprietary motor mount so a swap out would not be simple ( I call it "proprietary" but the patents expired many years ago) it is a one of a kind mount though, plus I assume most motors avail. in OZ would be metric & the Uni is a NEMA (National Electrical Manufacturers Association ) frame motor. If I was going to import 60 HZ equipment into the 50 HZ world would have a 3 phase machine, & use a Variable Frequency Drive (VFD) w/ a 240V single phase input & set the frequency for 60HZ. On another note if someone needs info on Delta & Rockwell/ Delta machines try searching the info at Old Wood Working Machines there is a lot of old threads on unisaws there, www.owwm.org and for manuals & other info www.owwm.com, the dot com site is limited to North American machines though. Since the OP seems to found the problem this is posted for info in the future if the need were to arise.


    Here is a link to a drawing of a unisaw motor http://www.electricmotorwarehouse.co..._saw_motor.htm
