重要な安全情報
Read and understand this entire manual before operating the Liftmaster 3 Ton Aluminum and Steel Low Profile High Lift Floor Jack. Failure to follow these instructions may result in serious injury or property damage. This floor jack is designed for lifting purposes only. Always use appropriate jack stands to support the vehicle after lifting. Never work under a vehicle supported only by a floor jack.
- 定格容量: 定格容量 3 トン (6000 ポンド) を超えないでください。
- 表面： Always use the jack on a hard, level surface. Avoid uneven ground or soft surfaces.
- 安定性： Ensure the vehicle is stable and cannot roll before lifting. Engage the parking brake and block wheels.
- ジャッキスタンド: Immediately after lifting, place appropriately rated jack stands under the vehicle's designated support points.
- オーバーロード： The dual pump quick lift hydraulic system is equipped with a safety valve to prevent overloading beyond rated capacity. Do not attempt to bypass this safety feature.
- メンテナンス： Regularly inspect the jack for damage or wear. Do not use if damaged.
設定
Before first use, perform the following steps to ensure proper operation and safety.
- 開梱: Carefully remove the floor jack from its packaging. Inspect for any shipping damage.
- ハンドルアセンブリ: Insert the handle into the handle socket on the jack. Ensure it is securely seated.
- ファスナーの確認: Verify that all nuts and bolts, especially those on the casters, are securely tightened. Loose fasteners can affect stability and operation.
- Bleeding the Hydraulic System: Air can become trapped in the hydraulic system during shipping. To bleed the system:
- Turn the handle counter-clockwise to fully open the release valve.
- Pump the handle rapidly 10-15 times without a load.
- ハンドルを時計回りに回してリリースバルブを閉じます。
- Test the jack by lifting it to its full height and then lowering it. Repeat if necessary until the jack operates smoothly.

操作手順
Follow these steps for safe and effective use of your floor jack.
- 車両を準備する: 車を硬く平らな場所に駐車してください。パーキングブレーキをかけ、地面に接地する車輪に輪止めを取り付けてください。
- ジャックの位置: Locate the vehicle's manufacturer-recommended lifting points. Position the jack saddle directly under the lifting point. The jack's ultra-low 2.95 inch (75mm) entry point is ideal for lower body frame cars, while its high lift range up to 19.68 inches (500mm) accommodates pickups and SUVs.
- 車両を持ち上げる: Turn the handle clockwise until the release valve is fully closed. Pump the handle to raise the vehicle. Lift the vehicle only high enough to place jack stands.
- ジャッキスタンドで固定します: 車両が希望の高さに達したら、直ちに適切な定格のジャッキ スタンドを車両の指定サポート ポイントの下に配置します。
- ジャッキを下げる: Slowly turn the handle counter-clockwise to open the release valve and lower the jack until the vehicle rests securely on the jack stands. Remove the floor jack.
- Remove Jack Stands and Lower Vehicle: When work is complete, raise the vehicle slightly with the floor jack to remove the jack stands. Then, slowly turn the handle counter-clockwise to lower the vehicle completely to the ground. Remove the floor jack and wheel chocks.

メンテナンス
定期的なメンテナンスにより、フロアジャッキの寿命が長くなり、安全に操作できるようになります。
- 潤滑: Periodically lubricate all moving parts, including the pivot points and casters, with light machine oil.
- 油圧流体: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or other non-approved fluids.
- クリーニング： Keep the jack clean and free of dirt, grease, and corrosive materials.
- Release Valve Threads: If the release valve becomes stiff or causes the jack to lower too quickly, apply a small amount of oil to the threads of the release valve mechanism. This can help ensure a smooth and controlled lowering action.
- ストレージ： 腐食を防ぎ、シール寿命を延ばすために、ラムを完全に引き込んだ状態でジャッキを清潔で乾燥した場所に保管してください。
