Lubrication [13] CAUTION Do not connect the power cord until lubrication is complete. If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result. Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your eyes or onto your skin. If the oil and grease get into your eyes or onto your skin, inflammation can result. Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting. Keep the oil out of the reach of children. • The sewing machine should always be lubricated and the oil supply replenished before it is used for the first time, and also after long periods of non-use. • Use only the lubricating oil specified by Brother. * If this type of lubricating oil is difficult to obtain, the recommended oil to use is . 1. Fill the arm oil tank and the bed oil tank with oil. NOTE: Be sure to add more oil when the oil level drops down to about one-third full in the oil gauge window (1). If the oil drops below the one-third full level in the oil gauge window (1), there is the danger that the sewing machine may seize during operation. 2. Remove the bobbin case and add 2-3 drops of oil to the rotary hook race (2). 3. If using the needle cooler (3), fill it with silicon oil (100 2 mm /s). (Refer to "5-3. Threading the upper thread" for details on using the needle cooler (3).) 2752B 2753B 3986M 17 BAS-342G PS 4. INSTALLATION 4-19. Connecting the power cord [14] CAUTION Be sure to connect the ground.

Attach an appropriate plug to the power cord (1). (The green and yellow wire is the ground wire.) 2. Insert the plug into a properly-grounded AC power supply. * The inside of the control box uses single-phase power. NOTE: • If the ground connection is not secure, electric shocks, operating errors or damage to electronic components such as P.C. boards may occur. • Do not use an extension cord.

If the machine head is tilted back, gently return it to its original position. (Refer to "4-5. Tilting back and returning the machine head".) 2. Turn on the power switch. 3. Check that no error numbers are displayed on the operation panel. If the safety switch (1) is not turned on, error [E050], [E051] or [E055] will occur. Check the installation position of the safety switch (1). 1. Turn off the power switch. 2. Loosen the two screws (2). 3.

If this is not observed, the machine head may become unbalanced and fall down, and serious injury or damage to the sewing machine may result. Ask your Brother dealer or a qualified electrician to carry out any maintenance and inspection of the electrical system. 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 Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your eyes or onto your skin. If the oil and grease get into your eyes or onto your skin, inflammation can result. Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting. Keep the oil out of the reach of children. Disconnect the air hoses from the air supply and wait for the needle on the pressure gauge to drop to “0” before carrying out inspection, adjustment and repair of any parts which use the pneumatic equipment. 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.
