## Questions & Answers

**Q: ギボシ端子に使用できますか？**
A: 使用できません。肉厚の為、カシメ形状が良くありません。個別圧着ペンチIWS-1440L、同時圧着ペンチIWS-0520B（矢崎ギボシにはHS-03BC）をご検討ください。

**Q: 平型端子に使用できますか？**
A: エーモン、矢崎、住友電装、日圧(JST)、ヒロセなどの国内メーカー品には使用できません。肉厚の為、カシメ形状が良くありません。個別圧着ペンチIWS-1440L、同時圧着ペンチIWS-0520Bをご検討ください。

**Q: 圧着工具（新品）のハンドル動作がかたい。正常ですか？**
A: 新品の場合、リングやピンがかたいことは正常です。しばらくお使いいただくことで少しずつなじみ、軽くなります。

**Q: ラチェット構成品ですか。**
A: ラチェット内蔵品です。

**Q: ハンドルが開かない時の解除方法は？**
A: ハンドルを強く握りこみ、電線とリングスリーブを押し潰すことで、ハンドルを解除することができます。ハンドルの外側方向（開く方向）には絶対に力を加えないでください。 手順① 工具を逆さまに持ち替え、両手でハンドルの先を握る 手順② ハンドルを両手で強く握り続ける 手順③ 緊急解除レバーをドライバーで動かしてみる。電線が固定されていても、誤ったダイスで圧着した端子・電線は使用できません。再度、正しい組み合わせで圧着作業を行ってください。
