3. インストール手順

Follow these steps to replace your old trimmer head with the new INGQI Trimmer Head. Always refer to your string trimmer's original manual for specific instructions if available.

3.1 必要なツール

• Wrench (size may vary depending on your trimmer's shaft bolt)
• 手袋

3.2 ステップバイステップのインストール

1. トリマーを準備します。 Ensure the string trimmer is turned off, the engine is cool, and the spark plug wire is disconnected to prevent accidental starting.
2. 古いトリマーヘッドを取り外す: Locate the bolt or nut securing the old trimmer head to the trimmer shaft. Use a wrench to loosen and remove it. Some trimmers may have a locking pin to hold the shaft still while loosening. Turn the bolt/nut in the direction indicated by your trimmer's manual (often reverse thread).
3. クリーンシャフト: Clean any debris or grass buildup from the trimmer shaft threads.
4. Install New Trimmer Head: Align the new INGQI Trimmer Head with the trimmer shaft. The head typically screws onto the shaft. Ensure it is seated correctly.
5. Secure the Head: Tighten the bolt or nut firmly. Do not overtighten, as this can damage the threads.
6. インストールの確認: Gently tug on the trimmer head to ensure it is securely attached and does not wobble. Reconnect the spark plug wire.

4. 操作手順

Once the trimmer head is securely installed, you can operate your string trimmer as usual. Always follow your trimmer's manufacturer guidelines for safe operation.

4.1 一般的な操作

• Start the trimmer engine according to its instructions.
• トリマーを両手でしっかりと持ちます。
• Maintain a balanced stance and keep the trimmer head away from your body.
• Cut grass by swinging the trimmer head from side to side, using the tip of the line.

4.2 Line Feeding

This trimmer head typically uses a bump-feed mechanism. To advance the trimmer line:

1. While the trimmer engine is running at full throttle, lightly tap the bottom of the trimmer head on a firm, flat surface (e.g., the ground).
2. The impact will release a small amount of line. The trimmer's line-cutting blade (if equipped) will trim the line to the correct length.
3. Repeat as necessary when the line becomes too short.

5. メンテナンス

定期的なメンテナンスにより、トリマー ヘッドの寿命が長くなり、最適なパフォーマンスが確保されます。

5.1 トリマーラインの交換

When the trimmer line runs out, it needs to be replaced. This head is designed for easy line reloading.

1. Turn Off Trimmer: トリマーがオフになっており、スパークプラグワイヤーが取り外されていることを確認します。
2. Remove Old Line (if any): If there are short pieces of line remaining, pull them out.
3. Align Head: Look for arrows or indicators on the trimmer head and align them. This typically aligns the internal spool with the line exit holes.
4. Insert New Line: Take a length of new trimmer line (refer to your trimmer's manual for recommended diameter and length). Push one end of the line through one of the line exit holes and continue pushing it through the head until it comes out the opposite exit hole.
5. Equalize Line: Pull the line through until an equal length extends from both sides of the trimmer head.
6. 風線: Rotate the bump knob or the top of the trimmer head in the direction indicated by an arrow (usually clockwise) to wind the line into the spool. Keep winding until only about 6-8 inches of line extend from each side.
7. 確認する： Ensure the line is securely wound and both ends are extended.
