KE-430F BE-438F 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 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, and consequently there is always a danger of injury that can be caused by these parts.
SAFETY INSTRUCTIONS! ! 1. Safety indications and their meanings ! This instruction manual and the indications and symbols that are used on the machine itself are provided in order to ensure safe operation of this machine and to prevent accidents and injury to yourself or other people. The meanings of these indications and symbols are given below. Indications! instructions which follow this term indicate DANGER! The instructions will result in death or serious injury.
! 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 electrical line noise or static electric noise.
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. Attach all safety devices before using the sewing machine. If the machine is used without these devices attached, injury may result.
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. 1 *Safety devices Eye guard Finger guard DT solenoid cover Thread take-up cover Side cover Rear cover, etc. 2 5 6 3 Be careful to avoid injury from the moving thread take-up.

TABLE OF ERROR CODES 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. If a malfunction should occur with the sewing machine, a buzzer will sound and an error code will appear in the display window. Follow the remedy procedure to eliminate the cause of the problem.
10. TABLE OF ERROR CODES Upper shaft motor-related errors Code Cause and remedy Sewing machine has continued to be used for a certain period after the “GREASEUP” notification appears E100 without the grease being applied (without the reset procedure being carried out). Apply grease and then carry out the reset procedure. (Refer to the service manual for the reset procedure.) Upper shaft did not stop at the needle up stop position when the sewing machine stopped.

E400 Turn off the power, and then check that connector P1 on the panel P.C. board and connector P3 on the motor P.C. board are properly connected. Communication error detected between the main P.C. board and the motor P.C. board when the power was turned on.
10. TABLE OF ERROR CODES Data editing-related errors Code Cause and remedy The enlargement ratio setting caused the sewing data to extend outside the sewing area. E500 Press the RESET key to clear the error. Set the enlargement ratio again. The enlargement ratio caused the data pitch to exceed the maximum pitch of 12.7 mm. E502 Press the RESET key to clear the error. Set the enlargement ratio again. Error in pattern data. E510 Press the RESET key to clear the error.
11. TROUBLESHOOTING㩷 11. TROUBLESHOOTING • Please check the following points before calling for repairs or service. • If the following remedies do not fix the problem, turn off the power switch and consult a qualified technician or the place of purchase.
