BIHUI LLG12 レーザーレベル（12ライン）ユーザーマニュアル

1. はじめに

This user manual provides comprehensive instructions for the safe and effective operation, maintenance, and troubleshooting of your BIHUI LLG12 Laser Level. Please read this manual thoroughly before using the device to ensure optimal performance and to prevent damage or injury.

2. 安全に関する注意事項

Always adhere to the following safety guidelines when operating the BIHUI LLG12 Laser Level:

• レーザー放射： Do not stare directly into the laser beam. Avoid direct eye exposure. The laser level emits Class 2 laser radiation.
• 保護眼鏡: Use the provided laser enhancement glasses (if included) to improve visibility of the laser lines, but note they do not offer eye protection against direct laser exposure.
• 子供たち： デバイスを子供の手の届かない場所に保管してください。
• 環境： 可燃性の液体、ガス、粉塵などが存在する爆発性雰囲気内ではレーザーレベルを操作しないでください。
• 変更点: レーザーレベルを改造したり分解したりしないでください。修理は認定されたサービス担当者のみが行う必要があります。
• バッテリーの安全性: Follow all battery manufacturer instructions for charging, handling, and disposal. Do not expose batteries to excessive heat or fire.
• ストレージ： 使用しないときは、デバイスを乾燥した涼しい場所に保管してください。

4. セットアップ

1. 開梱: Carefully remove the laser level and all accessories from the carrying case. Inspect for any signs of damage.
2. バッテリーの取り付け: Open the battery compartment and insert the rechargeable battery, ensuring correct polarity. Close the compartment securely. Charge the battery fully before first use.
3. 配置: Place the laser level on a stable, level surface. For elevated or precise positioning, attach it to the mini tripod or magnetic bracket using the mounting thread. Ensure the pendulum lock is in the unlocked position for self-leveling mode.
4. 環境： Ensure the working area is free from obstructions and that the ambient light conditions allow for clear visibility of the laser lines.

5. 操作手順

The BIHUI LLG12 offers multiple operating modes for various applications.

1. 電源オン/オフ:
   • To power on, slide the pendulum lock switch to the unlocked position. The laser level will automatically enter self-leveling mode and project horizontal and vertical lines.
   • To power off, slide the pendulum lock switch back to the locked position. This also secures the pendulum for transport.
2. セルフレベリングモード:
   • When the pendulum lock is unlocked, the device will self-level within its specified range (typically ±3°). If the device is outside this range, the laser lines will flash rapidly to indicate it cannot self-level. Adjust the position of the device until the lines become stable.
3. 手動モード（スロープ機能）:
   • To activate manual mode, power on the device with the pendulum lock in the locked position. The laser lines will be projected but will not self-level, allowing you to project lines at any angle.
   • This mode is useful for tasks like installing handrails or decorative patterns that require non-level lines.
4. 行の選択:
   • Press the 'H' button to cycle through horizontal line combinations (e.g., one horizontal, two horizontal, all horizontal).
   • Press the 'V' button to cycle through vertical line combinations (e.g., one vertical, two vertical, all vertical).
   • Press both 'H' and 'V' buttons to activate all 12 lines.
5. Pulse Mode (Outdoor Mode):
   • Press the pulse mode button (often indicated by a 'P' or a receiver icon) to activate pulse mode. This mode is used when working with a laser receiver (not included) for extended working ranges or in bright outdoor conditions. The laser lines will appear dimmer to the naked eye in this mode.

6. メンテナンス

適切なメンテナンスを行うことで、レーザー レベルの寿命と精度が確保されます。

• クリーニング： 柔らかくてamp cloth to clean the device. Do not use abrasive cleaners or solvents. Keep the laser emission windows clean for optimal beam clarity.
• ストレージ： Always engage the pendulum lock before storing or transporting the device. Store the laser level in its protective carrying case in a dry, cool place, away from direct sunlight and extreme temperatures.
• バッテリーのケア： If the device will not be used for an extended period, remove the battery to prevent leakage. Recharge the battery periodically to maintain its health.
• 較正： While the device is factory-calibrated, extreme impacts or prolonged use may affect its accuracy. If you suspect calibration issues, contact authorized service personnel.
