Study Tips: SQ4R Method
There are different variations to this note-taking method, but they all follow the same process. This method is mainly used for taking notes from a text, or a book. SQ4R is an acronym for:
- Survey: This is where you survey any preliminary information. This includes title, preface, chapter introduction, and illustrations to get a general idea of the topic.
- Question: This is where you create a general topic question about the chapter that you could answer later on. Often, you can add the words “what is” in front of the title to create your question.
- Read: This is where you read the text, and try to find the answer to your question.
- Recite: This could include reading certain passages aloud, or closing the book and trying to answer the question without reading the chapter.
- Relate: This is where you might take notes, and reflect on how all of the information comes together.
- Review: This is an opportunity to reflect on the content you have just been focusing on and write a short summary.
For practice, use the following instruction sheet. (You could also choose any instruction sheet that you really need to brush up on, and follow this example.)
- Before reading the sheet, look over the features of the text. The titles are: air compressor, maintaining the air compressor, Pneumatic Fastening Tools, and Operating Pneumatic Tools. There is a diagram containing the features of the air compressor. There is a text box. Read the text box first because it may contain a summary of the most important points.
- Question. In this course, you should be reading to answer a specific question. Perhaps this is an exam question you came across, got wrong, and need to know the answer. Let’s say, in this case, the exam question is:
“When using an air compressor, there are how many dials?”
a) one- indicating the pressure being supplied to the tool
b) two- one indicating the pressure supplied to the tool, and one indicating the ambient air pressure
c) two- one indicating the pressure supplied to the tool, and the other indicating the tank pressure
d) one- indicating the tank pressure

Topic 10 – Identify the Compressed Air (Pneumatic) System
The Air Compressor
While cordless tools are quickly taking over the construction trades, pneumatic tools still play a vital role in certain tasks. The source of compressed air, the air compressor, it the motor that drives these tools. Understanding the maintenance and operation of the air compressor is key knowledge a carpenter should possess. The air compressor (pictured right) is equipped with parts that moderate its operation to ensure it is safe for use. It possesses an automatic shutoff that prevents the tanks from being overfilled. It is also equipped with a safety relief valve which releases air past a certain pressure.
There is two pressure gauges situated on the air compressor. One indicates the pressure inside the tank. Typically, the motor will disengage when this reaches 120-130 PSI
