The first reason why the manual hydraulic truck can not be lowered is that it is in the raised position for a long time.
If the manual hydraulic pallet truck is in the raised position for a long time, it may cause some joints to rust due to the poor operating environment, resulting in the failure of operation and the inability to lower. At this time, you can remove the rust stains, replace the seriously rusted parts, and add lubricating oil at the same time.
The second reason why the manual hydraulic truck can not be lowered is that the oil pump is deformed.
Due to the poor quality of the manual hydraulic truck, the oil pump may be deformed and the hydraulic system may be damaged under normal use, so it cannot be lowered. At this time, the customer needs to replace the oil pump to solve the problem.
The third reason why the manual hydraulic truck can not be lowered is that the screw on the swing rod is not in the correct position.
Because the screw on the swing rod is not in the correct position, the manual hydraulic truck can not be lowered normally. We can put the finger handle in the lowering position to make room for operation and maintenance, and then turn the screw on the swing rod clockwise until the manual hydraulic truck is lowered.
