Turn the valve setting plate (2) upside down, and install it to the underside of the work table using the two wood screws (3) and washers (4) which are provided as accessories. 3. Install the air unit (5) to the valve setting plate (2) with two screws (1). 4. Connect the air hose (6). 5. Adjust the air pressure. (Refer to “9-10-4. Adjusting the air pressure”.) 1. Make holes in the beam as shown in the illustration above. (Button hole diameter is 5.4 mm.) Pneumatic work clamp ......Pitch 50 mm Reverse work clamp ......Pitch 120 mm 2. Install the air unit (7) to the beam with two accessory screws (8) and two bolts (9). 3. Connect the air hose (10). 4. Adjust the air pressure. (Refer to “9-10-4. Adjusting the air pressure”.) 3-20-2. Adjusting the speed controller The raising and lowering speeds for the work clamp can be adjusted by screwing the knobs on the valve in and out. Adjust the knob position to set the appropriate speed. If the upper knob is screwed inward, the work clamp raising speed becomes slower; if it is screwed outward, the raising speed becomes faster. If the lower knob is screwed inward, the work clamp lowering speed becomes slower, if it is screwed outward, the lowering speed becomes faster. The work clamp can be operated when the power is turned off by pressing the switch. If the manual button is pushed in and turned to the right, the work clamp can then be held in the raised condition. Note The valve knobs should be adjusted so that the left and right sides of the work clamp operate at the same speed. BAS-311F-0, 311F-L, 326F-0 4. LUBRICATION 4. LUBRICATION CAUTION Turn off the power switch before starting lubricating, otherwise the machine may operate if the foot switch is depressed by mistake, which could result in injury. 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, otherwise inflammation can result. Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and diarrhoea. Keep the oil out of the reach of children. Note 1: Fill the machine with oil when the oil level is down to about one-third full in the oil sight glass. If oil is not added and the oil drops below this level, there is the danger that the machine may seize during operation. Note 2: Be sure to let the machine operate for a while after adding the oil. Note 3: If there is no more oil on the felt of the shuttle race base, problems with sewing may result, so add oil to the felt until it is slightly soaked. Note 4: Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10N; VG10) for the machine oil. Lubrication points 1. Fill the arm-side oil tank with oil. 1190S BAS-311F-0, 311F-L BAS-326F-0 1191S(1) (2) X direction sewing home position 1192S 2. Fill the bed-side oil tank with oil. BAS-326F-0 When filling the bed oil tank with oil, move the presser arm (1) to the X direction sewing home position so that the oil hole in the X feed base cover L assembly (2) is aligned with the oil hole in the bed, and then fill the bed oil tank with oil.

If using the liquid cooling tank (1), fill it with silicon oil (100 * When setting up the sewing machine and when it mm2/s). hasn't been used for an extended period of time, be sure to add 2-3 drops oil to the felt. 5. CORRECT OPERATION 5-1. Selecting the needle and thread Different needles and threads are used for different sewing applications. Refer to the table at left for details on which needle and thread to select. Loosen the set screw (1), insert the needle (2) as far as it will go so that the groove is facing toward you and then tighten the set screw (1).
