I just got at an auction a Biro model 34 bandsaw for $135 and now that I
have cleaned it up a little I am not positive if it is set up to run on
220v. I think it is because the plug has one blade vertical and the other
horizontal in other words ( - ! like this). The ground pin is in the normal
position. Can anyone tell me an easy way to tell if I am correct? I don't
want to just plug it in and see what happens. After all I would hate to burn
the sucker up after almost giving myself a hernia picking this 400-500 pound
monster up and getting it home. As always thanks for the help. Larry
Have a look here
to see exactly what you have. Pay attention to the difference between plug and
Plug like this
is 120V 20A.
Plug like *this*
is 240V 20A.
Also be aware that the plug configuration does not necessarily indicate what
the motor actually needs -- it's *supposed* to match, but on used equipment,
somebody might have changed it incorrectly, and you don't have any way of
knowing that it really *does* match unless you check the motor wiring. There's
probably a diagram on the motor, or a label, that would indicate what it is.

Well, its a 20a plug, and 20a at 240v seems excessive, so it is probably
But, just to be sure
You can't really make a mistake because a 120v plug won't fit a 240v outlet.
Look at the motor plate. It should give the wiring diagram for 120 and 240
service. Then look at the wiring on the motor to see which way it is
connected. The field windings are connected in series for 240 and in
parallel for 120.
