The Secret to Reading and Interpreting Hydraulic System Schematics
The secret to being successful at reading and interpreting a schematic for a hydraulic system is really quite simple. Very often, technicians will forget that the symbols on schematics are really a completely different language of pictographs — pictures of what theobject does — used to represent the component. As you read this manual and begin to study the symbols inside, go to the extra effort to try and figure out why the symbols are drawn as they are. If you think about it, pumps will look like what pumps do, and all of the other symbols will come close to looking like what they are intended to be. As 1. 2. 3. you read the schematic, remember the...
