The machine achieves a longer distance from machine arm to needle by adopting a high long arm. This means the machine dramatically increases workability when sewing large products such as sofas and car seats.

The needle thread device is standard equipment. As a result, the needle thread at the start of sewing does not come out on the cloth, so the start of sewing beautiful finished seams. Operators use scissors less often and can prevent damage to the material caused by thread picking.

The machine's powerful top & bottom feed demonstrates its performance when sewing car fabric seats. The lift of the presser foot is as high as 16 mm, which responds to the sewing of heavy-weight materials.

The thread trimmer achieves consistent thread trimming regardless of thickness of the thread, i.e., from thin to thick thread. The machine has adopted the rotary thread trimming mechanism which matches, in particular, design stitch with thick thread for furniture and bags. The automatic thread trimmer improves workability and increases productivity. When compared with the sewing machine without a thread trimmer, the DU-1481-7 substantially decreases the consumption of thread. The knife pressure can be adjusted with the adjusting screw.

The adoption of the horizontal-axis double-capacity hook helps reduce the frequency of bobbin thread replacement, thereby promising sewing work with efficiency. This hook is also helpful not only when sewing with thick thread but also when sewing a long seam length.

Standard equipped with LED light to illuminate the hand of the needle. The operator can set the brightness which is easy to work, improving work efficiency.
