174102 Non-Reversing Speed Control
1. Set the speed adjust dial to “0” (full CCW).
2. Apply AC line voltage.
3. Set the POWER switch to the ON position.
4. Slowly advance the speed adjust potentiometer CW.
The motor slowly accelerates as the potentiometer is
turned CW. Continue until the desired speed is reached.
5. To coast the motor to a stop, turn the speed adjust
potentiometer to “0” or set the POWER switch to the
OFF position.
174107 Reversing Speed Control
1. Set the FORWARD/OFF/REVERSE switch to the OFF
position.
2. Set the speed adjust potentiometer to “0” (full CCW).
3. Apply AC line voltage.
4. Set the FOWARD/OFF/REVERSE switch to the desired
direction of rotation.
5. Slowly advance the speed adjust potentiometer CW.
The motor slowly accelerates as the potentiometer is
turned CW. Continue until the desired speed is reached.
6. To coast the motor to a stop, turn the speed adjust
potentiometer to “0” or set the
FORWARD/OFF/REVERSE switch to the OFF position.
