Manual hydraulic loader does not rise up how it happened?

galvanizing hand pallet truck is the most commonly used handling tool in factories, warehouses, workshops, because the shape is simple and powerful, but this simple device will often appear this or that problems, such as slow rise, slow down, or simply do not rise .
L does not rise, many people think it is not bad? In fact, this is not the case, many times only manual hydraulic pump truck inside the air, leading to the time of the hydraulic does not rise or slow. At this time only need a simple row of air can make manual handling vehicles intact.
The method of exhaust air is very simple, the following for you:
Manual hydraulic pallet truck generally has three stalls
1, the middle position is blocked, the stall car neither rise nor fall.
2, dial up is the gap, which is down the stalls, pressure relief gear.
3, down is linked to file, close the oil seal is allowed to increase its hydraulic pressure.
We only need to manually shift the stall gear stalls up, and then as usual pressure from the same pressure a few handles, this time although the car will not rise, but can exclude the air inside the pump, about 10-20 under pressure You can.
