4. INSTALLATION 4-3. Checking the machine pulley rotating direction CAUTION Do not touch any of the moving parts or press any objects against the machine while sewing, as this may result in personal injury or damage to the machine. 1. Insert the power cord plug into the wall outlet, and then turn on the power switch. 2. Depress the treadle slightly and check that the machine pulley starts to turn in the direction of the arrow (1). * If the direction of rotation is reversed, change the direction of rotation to the correct direction while referring to the instruction manual for the motor. 2980M 4-4. Alarm display (Semi dry type) 2981M The alarm display is a device that shows the time until the next greasing is required. (1) POWER indicator (green) The POWER indicator (1) only illuminates while the sewing machine is operating. It does not illuminate while the sewing machine is stopped. (The alarm display makes a total of the time that the POWER indicator (1) is lit.) NOTE: The POWER indicator (1) may not illuminate at times such as if the sewing machine is operating at a slow speed, or when operation starts again after having been stopped for several minutes, but this is normal and is not the sign of a malfunction. (2) GREASE indicator (red) If the GREASE indicator (2) illuminates and the buzzer sounds each time the treadle is depressed, it is time to apply grease. (See P. 30.) 13 T-8420B, 8450B, 8720B, 8750B
