BAS-311F-0, 311F-L BAS-326F-0 INSTRUCTION MANUAL Please read this manual before using the machine. Please keep this manual within easy reach for quick reference.
Thank you very much for buying a BROTHER sewing machine. Before using your new machine, please read the safety instructions below and the explanations given in the instruction manual. With industrial sewing machines, it is normal to carry out work while positioned directly in front of moving parts such as the needle and thread take-up lever, and consequently there is always a danger of injury that can be caused by these parts.
2 Notes on safety DANGER Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet before opening the face plate of the control box. Touching areas where high voltages are present can result in severe injury. CAUTION Environmental requirements Use the sewing machine in an area which is free from sources of strong electrical noise such as high-frequency welders. Sources of strong electrical noise may cause problems with correct operation.
CAUTION Sewing This sewing machine should only be used by operators who have received the necessary training in safe use beforehand. If using a work table which has casters, the casters should be secured in such a way so that they cannot move. The sewing machine should not be used for any applications other than sewing. Be sure to wear protective goggles when using the machine.
3 Warning labels The following warning labels appear on the sewing machine. Please follow the instructions on the labels at all times when using the machine. If the labels have been removed or are difficult to read, please contact your nearest Brother dealer. 2 1 3 4 Safety devices Eye guard Finger guard Thread take-up cover Belt cover Frame side cover, etc. High temperature warning display Be sure to connect the ground.

14. TROUBLESHOOTING 14. TROUBLESHOOTING Problem Cause Check Remedy Work clamp operation is sluggish. Sliding part of the work clamp lubrication Grease the sliding part of the work clamp. Presser lifter air tube is bent or damaged.* Pressure lifter air tube Straighten the bend in the tube or replace the tube. Presser lifter link is not moving back. Link return spring is unhooked. Hook the link spring properly. Work clamp operation is sluggish.
14. TROUBLESHOOTING Problem Upper thread breaks. Lower thread breaks. Skipped stitches occur. Cause Check Page Upper thread tension is too strong. Upper thread tension Adjust the upper thread tension. 25 Needle is installed incorrectly. Needle direction Install the needle so that the groove is facing forward. 21 Thread is too thick for the needle. Thread and needle Use the correct thread for the needle. 21 Thread take-up spring tension and height are incorrect.
14. TROUBLESHOOTING Problem Cause Check Sharpen or replace the fixed knife. Shuttle race thread guide position Adjust the position of the shuttle race thread gudie. 43 Needle bar lift amount Adjust the needle bar lift amount. 42 The movable knife does not pick up the thread because of skipped stitches at the sewing end. Skipped stitches at sewing end Refer to “Skipped stitches occur”. Movable knife position is incorrect. Movable knife position Adjust the position of the movable knife.
14. TROUBLESHOOTING Problem Unstable upper thread length Unstable needle up stop position Machine does not operated when power is turned on and foot switch is depressed. Cause Check Remedy Page Improper tension and height of thread take-up spring Thread take-up spring tension and height Adjust the tension and height of the thread takeup spring. 25 Improper adjustment of sub tension sub tension Needle up stop position fluctuates. See “Unstable needle up stop position”. Fixed knife is blunt.
15. OPTION 15. OPTIONS Programmer Used to create sewing patterns for the BAS-300F series. It can also be used to display error messages. Inner clamp device Used for efficient sewing around labels, emblems and tape; operates by air together with the outer presser, so material slip pages will not occur. One-touch clamping device Allows the clamp to be replaced quickly and easily, without the need for extra tools.
15. OPTION Needle cooler device This is a pneumatic-type needle cooler which prevents the thread breaking due to heat. It is particularly useful when sewing thicker materials at high sewing speeds. OT (One-touch) Presser Use according to particular sewing needs in order to provide an even clamping force. Soft presser At the first stage, the work clamp applies only a spring force so that the material can be positioned. Then at the second stage, air pressure provides a full clamping force.
