POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should
be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-
prong grounding type plugs and matching receptacle which will accept the machine's plug. Before connecting the
machine to the power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of
the same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
