Brother BAS-311E service manual Cleaning, Maintenance and inspection

CAUTION

Cleaning

Turn off the power switch before starting any cleaning work, otherwise the machine may operate if the start switch is pressed by mis- take, 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.

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 elec- trician to carry out any maintenance and inspection of the electrical system.

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 start switch is pressed by mis- take, which could result in injury.

•When carrying out inspection, adjustment and maintenance

•When replacing consumable parts such as the rotary hook and knife

Disconnect the air hoses from the air sup- ply and wait for the needle on the pressure gauge to drop to "0" before carrying out in- spection, 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 ex- tremely careful to observe all safety precau- tions.

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 origi- nal 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.

Have two people present to hold the machine head with both their hands when tilting it back or returning it to its original position.
