Brother BAS-311G User Manual
Programmable electronic pattern sewer with cylinder bed
•Sewing data is sewn faithfully and attractively
•High maximum sewing speed
•Economical operation with low power consumption
•Work clamp lift amount can be adjusted easily from the operation panel
The world's highest sewing speed has been achieved and beautiful seams can be produced even at high speeds. It provides high sewing quality and increases productivity for a wide range of applications while saving energy.
High quality sewn products made with beautiful stitching
High quality stitching exactly the way it is programmed even at
With adoption of the
Low thread tension sewing is possible with stable thread tension
Presser foot control mechanism always provides uniform thread tightness
When thickness of material has been changed, the height of the stepping presser foot is changed so that a fixed amount of presser foot moving is constantly provided. This prevents the stepping presser foot from lifting too much or being excessively pressed and thus uniform thread tightness can be obtained. The height of the stepping presser foot can be set with no tools required, simply by entering a numeric value from the operation panel or in a program.
Furthermore, you can use user programs to set the stepping presser foot height to the desired height separately for each sewing program.
Smooth and beautiful stitches can be produced with a minimum resolution of 0.05 mm
Since the data is resolved at 0.05 mm per pulse for the feed, slanted lines and curves are accurately sewn with beautiful finishes. Also, a simple single point embroidery motif can be sewn, and embroidering on heavy materials, which is not easy with a general embroidery machine, is also possible.
Productivity is increased with maximum sewing speed of 2,700 rpm
With the adoption of a Brother's unique direct drive motor, starting and stopping is quick. Machine time has been reduced by approximately 10% compared to the previous model and thus productivity is increased.

Powerful needle penetration force
A more powerful motor (550W) has been adopted. The needle penetration force is powerful even at low speeds, and there is plenty of power available for sewing thick materials.

Work clamp lift amount can be set on operation panel (Solenoid specification)
As the work clamp operation is controlled by a pulse motor, the work clamp lift amount can be set simply by entering a numeric value at the operation panel without need of using tools. Furthermore, you can use the user programs to set desired work clamp lift amount for each program respectively. No need to adjust the amount at every change of programs.
3 types of work clamp lowering operation (Solenoid specification)
You can select desired work clamp lowering operation from three patterns by changing the memory switch settings.
pressing operation is suitable for occasions when the positioning materials with the work clamp is not necessary while it is positioned with the feed plate beforehand.
Analog dropping: The work clamp comes down in direct proportion to the pedal depression amount without steps. You can lower it with making subtle positioning of materials.
* The factory setting is the
A compact flash (CF) card has been adopted for handling a large amount of data. Read and write speed is fast, which allows multiple data to be copied or moved to other sewing machines or computers for data management.
*The number of patterns and stitches which can be stored depends on the number of stitches for each program.
Easy programmer* with large color LCD
•Programs can be easily created in the same procedure as the programmer of the previous model.
•A shape of pattern data can be checked while it is created.
•Comments can be added to the program. Also, horizontal and vertical sizes are displayed so that programs of similar figures can be identified.
Sewing data can be managed with programmer
Sewing data management is easy because sewing data image can be displayed and sewing data can be copied and moved easily.
Sewing area 130x100mm
The sewing area of the
Evenly applied presser pressure
The angle of the work clamp can be adjusted. Pressure is given evenly to the front, rear and sides of the work clamp so that a sewn product can be clamped firmly and accurate sewing finish is obtained.
Changing sewing pattern is simple
Work clamp can be replaced quickly and accurately
Simply by loosening the two screws, the work clamp can be replaced quickly. It can also be installed accurately by using the positioning pins.
Feed plate can be replaced accurately
When replacing the feed plate, stitch data can be easily and accurately aligned with the feed plate by aligning the reference holes of the needle plate and the feed plate.
Driver phase can be adjusted easily
The driver phase can be adjusted from the side without tilting the sewing machine. This reduces time taken for the adjustment and improves productivity when materials are changed.
Pulley positioned in convenient location
The pulley is positioned in the convenient location on the side of the sewing
machine arm. Needle drop and hook timing can be checked easily.
The adoption of a linear guide (both X and Y feed directions) has improved feed durability.
Brother has established the “Brother Green Label” in conformity with ISO 14021 international standard and JIS Q14021 Japanese Industrial Standard.
Industry’s top energy saving with the direct drive system
Inner clamping device*
This is operated with the outer presser by air and so material slippage will not occur. It is suitable for sewing around labels, emblems and Velcro straps.
Upper thread nipper**
This holds upper thread after thread trimming. It prevents the thread from tangling on the back of material, thus giving a better sewing finish. It also prevents the thread from pulling out of a needle at sewing start.
Air wiper (vertical wiper)**
This is driven by a pneumatic cylinder and useful when a thread cannot be completely pulled out from fabric in sewing extra heavy materials.
It wipes upper thread in the horizontal direction and is used in conjunction with the inner clamping device.
Sewing data programming software
This is a software package that lets you create, edit and modify sewing patterns for electronic sewing machines using a personal computer with no skill required.
This is a pneumatic type needle cooler which prevents thread breakage due to heat. It is particularly useful for sewing heavy materials or sewing at high speeds.
Thread breakage detector**
When it detects thread breakage, the sewing machine stops automatically and warns its operator. It is helpful when one operator uses many machines at the same time.
Triple pedal for standing operation**
In addition to the start pedal, the right and left pedals operate independently. This allows fabric to be positioned even more precisely.
