Why can't the hand jack lift be lifted normally?

Light mini pallet truck are the most commonly used handling tools in factories, warehouses and workshops. Although the hand jack lift is simple in design but has powerful functions, this simple assembled light mini pallet truck usually has one or more problems, such as a hand jack lift that slowly rises, slowly descends, or does not rise properly.

When people can't properly upgrade the light mini pallet truck, many people think that the hand jack lift is broken? This is not the case. In many cases, the light mini pallet truck's oil pump contains air, so the hydraulic pressure does not rise or rise slowly. At this time, only the air in the hand jack lift needs to be exhausted, so that the light mini pallet truck can be normally lifted.

Exhausting the air from the hand jack lift is actually very simple and easy, now it is the introduce.

Light mini pallet truck usually have three gear positions

1 In the middle of the handle position of the hand jack lift is the positioning gear, which is similar to the neutral position in the car. At this time, the light mini pallet truck will not move up and down.

2 The handle of the hand jack lift is lifted up by the downshift, that is the pressure relief position of the fork is lowered.

3 The handle of the light mini pallet truck is lifted upwards, that is the oil seal is closed, and the hydraulic pressure causes the fork of the hand jack lift to rise.

We only need to put the handle of the light mini pallet truck to the top, then press the handle of the hand jack lift for several times, about 10-20 times, so that the air in the light mini pallet truck pump can be smoothly discharged, and the hand jack lift can also be upgraded normally.
