RH-9820 i [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 cover 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. Sources of strong electrical noise may cause problems with correct operation. Any fluctuations in the power supply voltage should be within ±10% of the rated voltage for the machine. Voltage fluctuations which are greater than this may cause problems with correct operation. The power supply capacity should be greater than the requirements for the sewing machine's power consumption. Insufficient power supply capacity may cause problems with correct operation. The ambient temperature should be within the range of 5°C to 35°C during use. Temperatures which are lower or higher than this may cause problems with correct operation. The relative humidity should be within the range of 45% to 85% during use, and no dew formation should occur in any devices. Excessively dry or humid environments and dew formation may cause problems with correct operation. In the event of an electrical storm, turn off the power and disconnect the power cord from the wall outlet. Lightning may cause problems with correct operation. The pneumatic delivery capability should be greater than the requirements for the sewing machine's total air consumption. Insufficient pneumatic delivery capability may cause problems with correct operation. Installation Machine installation should only be carried out by a qualified technician. Contact your Brother dealer or a qualified electrician for any electrical work that may need to be done. The sewing machine weighs approximately 120 kg. Installation of the sewing machine and adjustment of the table height should be carried out by four or more people. Do not connect the power cord until installation is complete. If this is not done, the sewing machine may operate if the start switch is pressed by mistake, which could result in serious injury. Hold the machine head with both hands when tilting it back or returning it to its original position. In addition, do not subject the machine head to extra force while it is tilted back. If this is not observed, the machine head may become unbalanced and fall over (together with the table), and serious injury or damage to the sewing machine may result. Be sure to connect the ground. If the ground connection is not secure, you run a high risk of receiving a serious electric shock, and problems with correct operation may also occur. ii RH-9820 All cords should be secured at least 25 mm away from any moving parts. Furthermore, do not excessively bend the cords or secure them too firmly with staples. If this is not observed, fire or electric shocks may result. Install belt covers to the machine head. If using a work table which has casters, the casters should be secured in such a way so that they cannot move. Be sure to wear protective goggles and gloves when handling the lubricating oil, so that it does not get into your eyes or onto your skin. If care is not taken, inflammation can result. Furthermore, do not drink the lubricating oil. Diarrhea or vomiting may result. Keep the oil out of the reach of children. 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. Be sure to wear protective goggles when using the machine. If goggles are not worn, there is the danger that if a needle breaks, parts of the broken needle may enter your eyes and injury may result. Do not touch any of the moving parts or press any objects against the machine while sewing, as this may result in personal injury or damage to the machine. Turn off the power switch at the following times. If this is not done, the sewing machine may operate if the start switch is pressed by mistake, which could result in serious injury. • When threading the needle • When replacing the needle • When not using the machine and when leaving the machine unattended If an error occurs in machine operation, or if abnormal noises or smells are noticed, immediately turn off the power switch. Then contact your nearest Brother dealer or a qualified technician. If the machine develops a problem, contact your nearest Brother dealer or a qualified technician. Cleaning Turn off the power switch before carrying out this operation. If this is not done, the sewing machine may operate if the start switch is pressed by mistake, which could result in serious injury. Be sure to wear protective goggles and gloves when handling the lubricating oil, so that it does not get into your eyes or onto your skin. If care is not taken, inflammation can result. Furthermore, do not drink the lubricating oil. Diarrhea or vomiting may result. Keep the oil out of the reach of children. Maintenance and inspection Disassembly, assembly, 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. Turn off the power switch and disconnect the power cord at the following times. If this is not done, the sewing machine may operate if the start switch is pressed by mistake, which could result in serious injury. • When carrying out inspection, adjustment and maintenance • When replacing consumable parts such as the loopers and knife Turn off the power switch before inserting or removing the plug, otherwise damage to the control box could result. 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 the power switch and air need to be left on when carrying out some adjustment, be extremely careful to observe all safety precautions. RH-9820 Hold the machine head with both hands when tilting it back or returning it to its original position. In addition, do not subject the machine head to extra force while it is tilted back. If this is not observed, the machine head may become unbalanced and fall over (together with the table), and serious injury or damage to the sewing machine may 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, otherwise inflammation can result. Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and diarrhea. Keep the oil out of the reach of children. Use only the proper replacement parts as specified by Brother. 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. Any problems in machine operation which result from unauthorized modifications to the machine will not be covered by the warranty. iii [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.
