Важная информация по безопасности
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.
- Номинальная мощность: Не превышайте номинальную грузоподъемность в 3 тонны (6000 фунтов).
- Поверхность: Always use the jack on a hard, level surface. Avoid uneven ground or soft surfaces.
- Стабильность: Ensure the vehicle is stable and cannot roll before lifting. Engage the parking brake and block wheels.
- Джек Стэндс: Immediately after lifting, place appropriately rated jack stands under the vehicle's designated support points.
- Перегрузка: 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.
- Обслуживание: Regularly inspect the jack for damage or wear. Do not use if damaged.
Настраивать
Before first use, perform the following steps to ensure proper operation and safety.
- Распаковка: Carefully remove the floor jack from its packaging. Inspect for any shipping damage.
- Ручка в сборе: Insert the handle into the handle socket on the jack. Ensure it is securely seated.
- Проверьте крепеж: 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:
- Поверните рукоятку против часовой стрелки, чтобы полностью открыть выпускной клапан.
- Pump the handle rapidly 10-15 times without a load.
- Поверните ручку по часовой стрелке, чтобы закрыть выпускной клапан.
- Test the jack by lifting it to its full height and then lowering it. Repeat if necessary until the jack operates smoothly.

Инструкция по эксплуатации
Follow these steps for safe and effective use of your floor jack.
- Подготовьте автомобиль: Park the vehicle on a hard, level surface. Engage the parking brake and place wheel chocks on the wheels that will remain on the ground.
- Установите домкрат: 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.
- Поднимите автомобиль: 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.
- Надежно закрепите с помощью подставок: Once the vehicle is at the desired height, immediately place appropriately rated jack stands under the vehicle's designated support points.
- Lower the Jack: 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.

Обслуживание
Регулярное техническое обслуживание обеспечивает долговечность и безопасную эксплуатацию вашего домкрата.
- Смазка: Periodically lubricate all moving parts, including the pivot points and casters, with light machine oil.
- Гидравлическая жидкость: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or other non-approved fluids.
- Уборка: 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.
- Хранилище: Храните домкрат в чистом, сухом месте с полностью втянутым штоком, чтобы предотвратить коррозию и продлить срок службы уплотнений.
