CHANGING MOTOR VOLTAGE

WARNING
!
MAKE CERTAIN to disconnect the machine from the
power source before working on motor.
Have a certified electrician make all electrical connec-
tions. All local and state codes must be maintained.
The motor supplied with the Drill Press is a dual voltage
115/230-volt, single phase motor. The motor is wired
from the factory for 115-volt operation. To change to
230-volt operation, proceed with the following instruc-
tions. It is also necessary to replace the 115 volt plug,
supplied with your machine, with a UL/CSA Listed plug
(not included) suitable for 230 volts and the rated cur-
rent of the motor. The motor with a 230 volt plug
should only be connected to an outlet having the same
configuration as the plug. No adapter is available or
should be used with the 230 volt plug.
1. Make sure switch is OFF and disconnect power
cord from power source.
2. Verify on the motor tag that motor is dual voltage.
3. If motor tag states that it is dual voltage remove
junction box cover on motor.
4. Using wiring diagram on inside of junction box
cover, reconnect motor leads for 230-volt operation.
5. Replace junction box cover.
6. Replace 115 volt plug with a UL/CSA Listed 230
volt plug rated for current of the motor.
7. The ON/OFF switch is a 4-pole switch and does not
need any modifications.
