Click on the links below to get 2 cheat sheets of hydraulic symbols. Print them off and use them for reference. These cheat sheets have a list of common hydraulic symbols and hydraulic schematic diagrams which are useful for reading, understanding and interpreting hydraulic schematics and circuit drawings. Click on the links below to see the Working Line-Pressure/Return Hydraulic symbols, Hydraulic Cylinder Symbols, Hydraulic Motors Symbols etc. Next week I'll put together another list of symbols you can print off and use as reference.
