below.
Adding Oil

Unscrew

being careful not to strip the plastic threads.
Hose Connections

Close the Air Control Valve (69), right or left.

Connect the high pressure air hose to the air outlet.
The outlet is 1/4” NPT. For easy connection or removal, a quick coupler (not supplied)
should be installed on the end of the outlet.
To extend the life of your air tools, it is recommended to install an oiler and water filter
in series with the air output line of the Air Compressor as shown below.

ranty.
