중요한 안전 정보
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.

- 표면: Always use the jack on a hard, level surface. Avoid uneven ground or soft surfaces.
- 안정: Ensure the vehicle is stable and cannot roll before lifting. Engage the parking brake and block wheels.
- 잭 스탠드: Immediately after lifting, place appropriately rated jack stands under the vehicle's designated support points.
- 과부하 : 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.

설정
Before first use, perform the following steps to ensure proper operation and safety.
- 짐 풀기: Carefully remove the floor jack from its packaging. Inspect for any shipping damage.
- 핸들 어셈블리: Insert the handle into the handle socket on the jack. Ensure it is securely seated.
- 패스너 확인: Verify that all nuts and bolts, especially those on the casters, are securely tightened. Loose fasteners can affect stability and operation.
- 유압 시스템 공기 빼기: 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.
- 핸들을 시계 방향으로 돌려 릴리스 밸브를 닫습니다.
- Test the jack by lifting it to its full height and then lowering it. Repeat if necessary until the jack operates smoothly.

작동 지침
Follow these steps for safe and effective use of your floor jack.
- 차량 준비: 차량을 단단하고 평평한 곳에 주차하십시오. 주차 브레이크를 걸고 지면에 닿아 있을 바퀴에 고임목을 올려놓으십시오.
- 잭 위치: 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.
- 차량을 들어 올리세요: 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.
- 잭 스탠드를 사용하여 고정하십시오: 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.

유지
Regular maintenance ensures the longevity and safe operation of your floor jack.
- 매끄럽게 하기: Periodically lubricate all moving parts, including the pivot points and casters, with light machine oil.
- 유압유: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or other non-approved fluids.
- 청소: 잭을 깨끗하게 유지하고 먼지, 기름, 부식성 물질이 묻지 않도록 하십시오.
- 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.
- 저장: 부식을 방지하고 씰의 수명을 연장하려면 잭을 깨끗하고 건조한 곳에 램을 완전히 수축시킨 상태로 보관하십시오.
