4. MAINTENANCE
4.1 MAINTENANCE SAFETY
1. Turn off engine and relieve pressure before servicing
2. Open all manual drain valves within the area to be serviced.
3. Isolate the compressor from the compressed air supply by closing a manual shutoff valve upstream
and downstream from the compressor. Display a sign in clear view at the shutoff valve stating that the
compressor is being serviced.
4. Lock open a pressure relief valve within the pressurized system to allow the system to be completely
de-pressurized. NEVER remove a plug to relieve the pressure!
5. Wait for the unit to cool before starting to service. Temperatures of 125 degrees F can burn skin.
Some surface temperatures exceed 350 degrees F when the compressor is operating.
