Check Arbor Rotation (3 Phase Only)
Check arbor rotation with arbor nut and arbor collars removed. Open line disconnect to the saw
to remove arbor nut and collars, close the line disconnect and start saw. The rotation of the ar-
bor must be clockwise as indicated on the arrow on the nameplate. If the rotation is counter-
clockwise, the incoming wires are not properly connected to the switch box. To change the di-
rection reverse any two of the wires leading to the switch box from the power supply.
Changing Voltage on dual voltage motors
and Resetting Thermal Protection
Dual voltage motors can be operated on either of the two voltages indicated on the motor
nameplate. The voltage setting from the factory can be found on the cover of the magnetic
starter . To change the voltage:
1. Change the motor lead connections as shown on the diagram on the inside cover of the
motor conduit box. This is also found on page 23
in this manual. Disconnect and lockout the
power supply before attempting voltage change.
2. Reconnect the transformer in the magnetic starter as shown in the diagram on the inside of
the starter box cover. This is also found on pages 23
of this manual.
3. Replace or adjust the thermal overload protectors (D) using dial (A), see below right) with
those rated at the desired amperage range. See page 23
of this manual. If the overloads
trip you will need to press reset button (C) to resume operation.

Overload Protection
Your saw is equipped with automatic reset thermal overload protection. To restart after ther-
mals have tripped, wait until the motor cools, then press the saw start button. If overloads con-
tinue to trip, the machine is being overloaded. Do not continue to operate under these condi-
tions. This could indicate an electrical problem take the time to find the trouble and correct it,
see the electrical trouble shooting section of this manual.
