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 high-frequencywelders.

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 electrical consumption.

Insufficient power supply capacity 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.

The ambient temperature should be within the

range of 5 to 35 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.

Avoid exposure to direct sunlight during use. Exposure to direct sunlight 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.

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 more than 65 kg. (311F-0),70 kg(311F-L,326F-0)The installation should be carried out by two or more people.

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

Hold the machine head with both hands by two or more people 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.

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.

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, otherwise there is the danger that fire or electric shocks could occur.

Install the belt cover and the frame 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 oil or eat the grease under any circumstances, as they can cause vomiting and diarrhoea.

Keep the oil out of the reach of children.

3-20-2.Adjusting the speed controller

The raising and lowering speeds for the work clamp can be adjusted by screwing the knobs on the valve in and out. Adjust the knob position to set the appropriate speed.

If the upper knob is screwed inward, the work clamp raising speed becomes slower; if it is screwed outward, the raising speed becomes faster.

If the lower knob is screwed inward, the work clamp lowering speed becomes slower, if it is screwed outward, the lowering speed becomes faster.

The work clamp can be operated when the power is turned off by pressing the switch.

If the manual button is pushed in and turned to the right, the work clamp can then be held in the raised condition.

Note

The valve knobs should be adjusted so that the left and right sides of the work clamp operate at the same speed.

CAUTION

Turn off the power switch before starting lubricating, otherwise the machine may operate if the foot switch is depressed 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 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.

Note 1: Fill the machine with oil when the oil level is down to aboutone-thirdfull in the oil sight glass.

If oil is not added and the oil drops below this level, there is the danger that the machine may seize during operation.

Note 2: Be sure to let the machine operate for a while after adding the oil.

Note 3: If there is no more oil on the felt of the shuttle race base, problems with sewing may result, so add oil to the felt until it is slightly soaked.

Note 4: Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10N; VG10) for the machine oil.

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 drive upside down or backwards may damage 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, telephones, 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 damaged. 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 cleaning disk is used and the lifetime of the cleaning disk will become short. Next time you clean it, select a different number.

3.After the cleaning is completed, the “E.4F” error appears. The error appears because the cleaning disk has no data. This is normal.

4.Cancel the error and eject the cleaning disk.

8. CLEANING AND INSPECTION

CAUTION

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 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.

Wait until the motor has cooled down before cleaning the air holes.

The motor may be hot immediately after it has been used, and it may cause burns if touched.

8-2.Lubrication

Note 1: Fill the machine with oil when the oil level is down to aboutone-thirdfull in the oil sight glass.

If oil is not added and the oil drops below this level, there is the danger that the machine may seize during operation.

Note 2: Be sure to let the machine operate for a while after adding the oil.

Note 3: If there is no more oil on the felt of the shuttle race base, problems with sewing may result, so add oil to the felt until it is slightly soaked.

Note 4: Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10N; VG10) for the machine oil. Lubrication points refer to “4. LUBRICATION”.

15. OPTION

15. OPTIONS

Programmer

Inner clamp device

One-touchclamping device

Used to create sewing patterns for the BAS-300Fseries. 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 adjustment that has been previously required for other clamps is no longer necessary.

Milling device

This device can be used to cut a variety of objects such as grooves, holes, and outline shapes in plastic or aluminum sheets.

This device is available by special order. Please contact your nearest Brother dealer.

WP stitch device Automatic bobbin changer

Increases the stitch creation range for perfect stitches.

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 remaining and replacing bobbins, so that productivity can be increased.

Snap fastener and hook attachment device

Needle thread presser device 3-Pedalfoot switch

2-steppresser foot device

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 allows 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-steppresser foot device 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

72

15. OPTION

Needle cooler device

OT (One-touch)Presser

Soft presser

Cassette presser

This is a pneumatic-typeneedle cooler which prevents the thread breaking due to heat. It is particularly 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 material 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 operation can be carried out while sewing is in progress.

Overlapping operations are thus possible, which can greatly boost productivity.

Play prevention work clamp

This work clamp prevents any play from occurring in the

 

 

clamp.

Thread wiper, side type

Wipes the upper thread away to the side when an inner

clamping device is being used.

 

Air wipper device

The thread wiper is driven by a pneumatic cylinder.

 

2-stepthread tension device

Allows the upper thread tension to be switched between

two settings at any position desired by using the

 

programmer.

Thread take-updevice

After the thread is trimmed, an upper thread trailing length,

 

 

which is handy when sewing light materials where normal

 

trailing thread lengths can often lead to the thread pulling

 

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 automatically by a pneumatic

 

cylinder. In addition, the programs can be set so that the

 

cassette is ejected automatically.
