2.1.8 The screw (9) in Fig 5 is used to adjust the truck situation. When the truck
body lifts and then drops at once, you should turn the screw (9) a little
counter-clockwise. And then try to operate truck again. Do the action until
truck body lifts normally. When truck body lifts and won’t not drop, you
should turn the screw (9) a little clockwise. And then try to operate truck again.
Do the action until truck body could drops normally. The external hexagon nut
(10) of screw (9) plays the locking function in the truck. So you should undo
the external hexagon nut (10) before adjusting truck body. When you finish the
adjustment action, please remember to lock the hexagon nut (10).
