CAUTION

Sewing

This sewing machine should only be used by opera- tors who have received the necessary training in safe use beforehand.

The sewing machine should not be used for any applications other than sewing.

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.

Set the needle to the needle up stop position before turning on the power.

If this is not done, the wiper may strike the needle, which might cause the needle to break.

Turn off the power switch at the following times, otherwise the machine may operate if the foot switch is pressed by mistake, which could result in injury.

If using a work table which has casters, the casters should be secured in such a way so that they cannot move.

Attach all safety devices before using the sewing machine. If the machine is used without these devices attached, 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.

If an error occurs in machine, 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

Set the needle to the needle up stop position before turning on the power.

If this is not done, the wiper may strike the needle, which might cause the needle to break.

Turn off the power switch before carrying out cleaning, otherwise the machine may operate if the foot switch is pressed 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 in- flammation can result.

Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vom- iting and diarrhoea.

Keep the oil out of the reach of children.

Maintenance and inspection

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.

Set the needle to the needle up stop position before turning on the power.

If this is not done, the wiper may strike the needle, which might cause the needle to break.

Turn off the power switch and disconnect the power cord from the wall outlet at the following times, otherwise the machine may operate if the foot switch is pressed by mistake, which could result in injury.

•When carrying out inspection, adjustment and maintenance

•When replacing consumable parts such as the rotary hook

If the power switch needs to be left on when carrying out some adjustment, be extremely careful to observe all safety precautions.

Hold the machine head with both hands when tilting it back or returning it to its original position. Furthermore, after tilting back the machine head, do not push the face plate side or the pulley side from above, as this could cause the machine head to topple over, which may result in personal injury or damage to the machine.

Use only the proper replacement parts as specified by Brother.

If any safety devices have been removed, be abso- lutely 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.
