6. 操作手順
6.1 ステッチの選択
Your HIROBOT FHSM-520A machine features 16 built-in stitch patterns. Rotate the stitch selector dial to choose your desired stitch. The available stitches include straight, zigzag, blind hem, and various decorative patterns.
Note: Stitches 9, 10, 11, and 12 are specifically designed for buttonholes and cannot be used for regular sewing. For general and decorative sewing, select other stitch patterns.

A visual guide illustrating the 16 built-in stitch patterns of the HIROBOT FHSM-520A. These include straight stitches (1-4), decorative stitches (5-8), buttonhole stitches (9-12), and overlock stitches (13-16). Each stitch type is demonstrated on a fabric swatch.
6.2 糸調子の調整
The upper thread tension needs to be adjusted according to the fabric type and thread thickness to achieve balanced stitches. Rotate the thread tension dial to increase or decrease tension. A balanced stitch will have both upper and bobbin threads meeting evenly between the fabric layers.
一般的な推奨事項:
- Chiffon: Tension 2-3
- Pure Cotton: Tension 3-4
- Linen: Tension 4-5
- Denim: Tension 4-5
These are reference suggestions; always test on a scrap piece of your fabric.

This image illustrates the adjustable upper thread tension dial, crucial for achieving smooth stitches on various fabric types. Recommended tension settings are provided for chiffon (2-3), pure cotton (3-4), linen (4-5), and denim (4-5), emphasizing that adjustments may be needed based on fabric density.
6.3 Reverse Sewing Function
To reinforce stitches at the beginning and end of a seam, use the reverse sewing function. Press and hold the reverse button to sew backward. Release the button to resume forward sewing. This function is typically available for straight stitches (1-4).

This image highlights the reverse sewing function, activated by pressing a button. It shows how the machine can sew backward for reinforcement, specifically for stitches 1-4. The design also includes a free arm for sewing sleeves and cuffs.
6.4速度制御
The machine offers two ways to control sewing speed:
- スピードスイッチ: Use the 'L' (Low) and 'H' (High) switch on the machine for a constant speed.
- フットペダル: For variable speed control, connect the foot pedal. Gentle pressure results in slower stitching, while firmer pressure increases the speed.
6.5 ファブリックの互換性
The HIROBOT FHSM-520A is designed to sew a variety of fabrics, from lightweight cotton to heavier denim. It can handle 4-6 layers of fabric with a total thickness of up to 2.5mm.
Supported Fabrics: Pure Cotton, Denim, Linen, Oxford, Mixed Yarn, Chemical Fiber, Modal, Corduroy.
Important: Avoid sewing excessively thin fabrics directly. If necessary, place a layer of A4 paper under the thin fabric to increase its thickness and prevent it from being pulled into the needle plate.

This image demonstrates the machine's capability to sew through 4-6 layers of fabric, up to a total thickness of 2.5mm. It also highlights the support for both 1-needle, 1-thread and 2-needle, 2-thread functions.

7. メンテナンス
Regular maintenance ensures the smooth operation and extends the lifespan of your sewing machine.
- クリーニング: 小さなブラシを使って、ボビン部分と送り歯の糸くずやほこりを定期的に取り除いてください。清掃する前に、必ずミシンの電源プラグを抜いてください。
- 針の交換: Replace needles frequently, especially when they become dull, bent, or if you notice skipped stitches. Use the correct needle type and size for your fabric.
- ストレージ: 使用していないときは、機械を乾燥したほこりのない環境に保管してください。

8。 トラブルシューティング
ミシンで問題が発生した場合は、次の一般的な問題と解決策を参照してください。
- スレッドの切断: Check if the machine is threaded correctly (both upper and bobbin threads). Ensure the thread tension is not too high. Use good quality thread. Replace a bent or dull needle.
- スキップされたステッチ: This is often caused by an incorrect or dull needle. Ensure the needle is inserted correctly and replace it if necessary. Check upper threading and tension.
- 機械の詰まり: Incorrect threading, especially of the bobbin, is a common cause. Remove all threads, clean the bobbin area, and re-thread carefully following the instructions. Ensure the fabric is not too thick for the machine.
- 不均一なステッチ: Adjust the upper thread tension. Ensure the bobbin is wound evenly.
- マシンが起動しない: Check if the power adapter is securely plugged in and the power switch is 'ON'. Ensure the foot pedal is connected correctly if using it.
