10. STANDARD ADJUSTMENTS 10. STANDARD ADJUSTMENTS CAUTION Maintenance and inspection of the sewing machine should only be carried out by a qualified technician. Ask your Brother dealer or a qualified electrician to carry out any maintenance and inspection of the electrical system. Hold the machine head with both hands when tilting it back or returning it to its original position. In addition, do not apply excessive force when tilting back the machine head. The sewing machine may become unbalanced and fall down, and serious injury or damage to the sewing machine may result. Turn off the power switch and disconnect the power cord before carrying out the following operations. If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result. • Inspection, adjustment and maintenance • Replacing consumable parts such as the rotary hook If the power switch needs to be left on when carrying out some adjustment, be extremely careful to observe all safety precautions. If any safety devices have been removed, be absolutely sure to re-install them to their original positions and check that they operate correctly before using the machine. 10-1. Checking the machine head switch Check that the machine head switch is turned on as shown in the illustration. NOTE: If the machine head switch is not turned on, errors "E050", "E051" and "E055" will be generated. 10-2.
