Steps
Before use: First, check your off-road jack, including whether the pins are damaged and whether the lock holes on the support rods are blocked. Also, ensure that everyone around the car is standing in a safe position before starting to turn the handle.
overhead lift
1. Engage the parking brake on your four-wheel drive vehicle, and it's best to wedge a log or stone under the wheels to prevent the vehicle from sliding on the road surface.
2. When using a jack, keep the handle upright.
3. Place the jack on a solid and level surface. If the ground is soft or sandy, you need to find a way to add something that serves as a base, such as concrete blocks or bricks.
4. Move the direction lock to the "UP" position.
5. Grab the handle and lift it up until the jack nose just reaches the support point. Be careful not to use weak spots like hollow pipes or places where the contact is not firm and easy to slip as support points.
6. Grip the handle with both hands and carefully rock it up and down. When you rock the handle down, the vehicle will be lifted. Meanwhile, observe the vehicle for any sliding or other movement. If you find any instability, stop immediately. Additionally, do not use a long pole on the handle, as the other mechanical devices are not designed to bear these loads.
7. Do not lift the four-wheel drive car to an unnecessary height, the higher you lift it, the less stable the operation will be. In normal circumstances, do not lift the tires more than 5CM above the ground.
8. After you lift the car, remember to fix the handle with the handle clamp in a vertical position.
9. If you want to change a tire, don't rely solely on a truck jack. First, ensure that the tire is wedged in place, and then place stones or logs under the car's frame. Only after the car is slowly placed on these wedges can you proceed with the tire change.
"Release：
1. When you lower your off-road jack, it must have at least 150 pounds of pressure on it, or it will slip off the support pole by itself.
2. First, push the crank handle to the upright position.
3. Then, insert the directional lock into the "DOWN" position.
4. Start to rock the handle up and down, do not put your body or face against the handle, this can prevent accidental operation or in case of a hand slip, the handle will rebound back to its upright position and hit your teeth.
Maintenance of Off-Road Jacks
Although the off-road jack is a fully metal tool, you still need to take good care of its maintenance work. After use, clean it thoroughly to prevent the pin holes from being blocked, and apply a layer of WD-40 universal corrosion-resistant lubricant, or wool fat, which is actually very good with white lithium lubricant. If you are a careful person, you can also use a jacket to put it away.
