2、先拉“气垫”手拉阀，看看工作台有没有上升动作，没有上升动作，将减压

2, first pull "cushion" Hand valve, there is no table look-up operation, there is no upward movement, downward pressure reducing valve knob black, while black knob is rotated downward, the observed changes of the table, work there are slight upward movement stage, this time the pressure cushion has been adjusted, and then pull "jar" hand valve, vibration generation. When "real shock", "air cushion" followed by two hand valve back into place, the shaking stops.

2, first pull the "air cushion" hand pull valve, see if the workbench has no rising action, no rising action, the pressure relief valve black knob rotation downward, in the downward rotation of the black knob at the same time, observe the changes of the workbench, the workbench slightly upward action, at this time the air cushion pressure has been adjusted, and then pull "shock" hand-pull valve, vibration. When the "shock", "air cushion" two hand-pull valves in turn to press back in place, vibration stop.

2. First pull the "air cushion" hand pull valve to see if the worktable moves up or not. Rotate the black knob of the pressure reducing valve downward. While rotating the black knob downward, observe the change of the worktable. The worktable slightly moves up. At this time, the air cushion pressure has been adjusted, and then pull the "shock" hand pull valve to generate vibration. When the two hand pull valves of "vibrating" and "air cushion" are pressed back to their original positions, the vibration stops.<br>
