Contact your Brother dealer or a qualified electrician for any electrical work that may need to be done.

The sewing machine head weighs more than 65 kg (311F-0), 70 kg (311F-L, 326F-0). The installation should be car ried out by two or more peopl e.

Do not connect the power cor d until installatio n is complete, otherwise the machine may operate if the foot switch is depressed by mistake, which could result in injury.

Be sure to connect the ground. If the ground connection is not secure, you run the risk of receiving a serious electric shock.

Hold the machine head with both ha nds by two or more peple when tilting it b ack or r eturning it to its original position. Furth er more, 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.

All cords should be sec ured at least 25 mm awa y from any moving parts. Furthermore, do not excessively bend the ca ble or secure it too firm ly staples, otherwise there is the danger that fire or electric shocks could occur.

Install the belt cover and the f rame side cover to the machine head and motor.

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 and grease, so that they do not get into your eyes or onto your skin, otherwise inflammation can result. Furthermore, do not drink the oi l or eat the gr ease under any circumstances, as they can cause vomiting and diarrhoea. keep the oil out of the reach of children.

3. To eject the disk, press the eject button (5).

Note

Slide the write protector (6) on the back of the disk up (the window opens) to lock the disk and prevent accidental erasure of the disk contents. Inserting the disk into the dri ve upside down or backwards may dam age the drive and will prevent reading or writing of data.

Be sure to store your disks away from any magnets or magnetic sources, including radios, televisions, tele-

phones, and other devices. Magnetism can erase or damage disk contents. Also, be careful to prevent exposure of the disk to oil or dust. Be sure to make a copy of the floppy disk containing sewing data and keep the master floppy disk. When the R / W operation is not in operation, eject the floppy disk from the floppy disk drive and keep it in a case for floppy disk only to prevent exposure of the disk to dust. When the “E.4F” error (Reading error of sewing data) occurs very often;

1. Clean the floppy disk drive using the cleaning disk.

2. Read the sewing data. If the “E.4F” error occurs again, the floppy disk may be dam aged. In this case, clean the floppy disk drive with the cleaning disk again.

3. Read the sewing data from the master floppy disk and write it in a new floppy disk. Do not use any damaged floppy disks again.

How to use the cleaning disk

1. Insert the cleaning disk into the floppy disk drive.

2. Select a program number (0-9), and press the “R/W” switch. If you select the same program number for cleaning every time, the same location of the clea ning dis k is used and the lifetim e of the cleaning dis k will becom e shor t. Next tim e you clean it, select a different number.

3. After the cleaning is com pleted, the “E.4F” error appear s. The error appears because the cle aning disk has no data. This is normal.

4. Cancel the error and eject the cleaning disk.

15. OPTIONS

Programmer

Inner clamp device

One-touch clamping device

Milling device

WP stitch device

Used to create sewing patterns for the BAS-300F series. It can also be used to display error messages.

Used for efficient sewing around labels, emblems and tape; operates by air together with the outer presser, so material slip pages will not occur.

Allows the clamp to be replaced quickly and easily, without the need for extra tools. The positioning adjus tment that has been previously required for other clamps is no longer necessary.

This device can be used to cut a variety of objects such as grooves, holes, and o utline s hapes in plastic or alum inum sheets. This device is available by special order. Please contact your nearest Brother dealer.

Increases the stitch creation range for perfect stitches.

Automatic bobbin changer

Snap fastener and hook attachment device

Needle thread presser device

3-Pedal foot switch

2-step presser foot device

When the amount of bobbin thread remaining becomes low, this device automatically replaces the bobbin. This reduces the need for tasks such as checking the amount of bobbin thread rem ainin g an d replac ing bobbins, so th at productivity can be increased.

This attachment is for holding snap fasteners and hooks.

This allows the upper thread to be securely placed under the material for the first stitch at the sewing start.

In addition to a start pedal, the right and left pedals operate independently which allo ws positioning with even greater precision.

When there is difference in thickness of a work piece within one pattern, for example, when the work piece includes joints to be sewn, the 2-step presser foot dev ice changes the height of the presser foot in your desired position. This prevents stitches from skipping and ensures that high sewing quality is always maintained.

Thread breakage detector device

Available as rotary type or fiber type, stops sewing when a thread breakage is detected and warns the operator.

BAS-311F-0, 311F-L, 326F-0

15. OPTION

Needle cooler device

OT (One-touch) Presser

Soft presser

Cassette presser

This is a pneumatic-type needle cooler which prevents the thread breaking due to heat. It is partic ularly useful when sewing thicker materials at high sewing speeds.

Use according to particular sewing needs in order to provide an even clamping force.

At the first stage, the work clamp applies only a spring force so that the m aterial can be positioned. Then at the second stage, air pressure provides a full clamping force.

This allows the operator to hold two clamps so that the preparation for the next o per ati on c an be carried out whil e sewing is in progress. Overlapping operations are thus possible, which can greatly boost productivity .

Play prevention work clamp

Thread wiper , side ty pe

Air wipper device

2-step thread tension device

Thread take-up device

This work clamp pr events any play from occurring in the clamp.

Wipes the upper thread away to the side when an i nner clamping device is being used.

The thread wiper is driven by a pneumatic cylinder .

Allows the upper thread tension to be switched between two settings at any position desired by using the programmer.

After the thread is trimmed, an upper thread trailing length, which is handy when s ewing light m aterials where norm al trailing thread lengths can often le ad to the thread pullin g out. (311F series: Solenoid type, 326F: Pneumatic type)

Automatic ejector

When the reflective plate of the cassette is detected by the sensor, the cassette is held automatic ally by a pneum atic cylinder. In addition, the programs can be set so that the cassette is ejected automatically.
