Our units have a sight glass and the oil should be in the middle of the sight glass.

• First, you need to determine what types of tasks or jobs you will perform. A number of jobs such as inflating, spray painting, applying spray foam insulation, and sanding require various sizes of air compressors and tank sizes.
• Second, determine which types of pneumatic tools you will us. Different tools require different air pressure and volume (CFM) to operate properly. Choose an air compressor with higher air volume output (CFM) than the tools that will be used.
• Third, determine if the tool load will be used for light or intermittent duty or for continuous, heavy duty. The heavier the usage, the larger the air compressor and air tank size (in gallons) needs to be.
• Finally, determine the electrical power you have available.
• We advise our customers not to under buy, in order to save money, because it’s always better to have a little more air than needed.

yes, the factory oil its good only for 8 hours, then should be changed after 40 hours then every 200 hours..

Production units are not always set at the maximum operating pressure from the factory. However, most units can be field adjusted to the desired pressure. NEVER adjust the pressure above the Rated or Maximum Operating Pressure.
