9-1.POWER SYSTEM AND CONTROL PANEL
The electrical rating of your band saw is either with 230 volt-single phase,(or AC
power volt-3 phase), magnetic control.
Before connecting your machine to an electrical power system, be sure the motor
shaft is running in the correct direction.
We recommend that fuse with a 2 amp, dual element, time lag fuse, to be used to
supply power to all machines regardless of their electrical rating.
Refer to the electrical wiring diagram supplied with your machine for instructions
on how to connect saw to power source. Power must be cut off when wheel cover
is opened or during repairing.
Please check the moving direction of the blade. If the blade is moving in the
wrong direction, please re-connect the wire.
