Did the master tell you what the paver could not reach?
Paving function start, telescopic function, hydraulic, circuit, control, 3 parts, first simple, in complex, simple, that is, visual inspection, look at the pump, cylinder, etc., to listen to the sound of the pump is normal.
Not to see what problems, not to listen to what the problem is, from the starting circuit and control circuit, is a system, if the switch directly through the wire (wire) electric control valve, check whether to reach the valve block, the valve block has power, if an electric coil, check valve is good, check in spool valve group.
If it is a good telescopic cylinder leaks or pumps have problems. If plus the control system (such as modules) directly, and above the same, check the control valve directly whether there is no voltage, no, check the module to the switch part, if there is electricity, and the same as above. For reference only, for communication only.
