3. Turn regulator knob (F) counterclockwise until fully closed. Ensure
regulated pressure gauge reads 0 psi.
4. Remove hose and accessory.
5. Drain the air tank. See Draining Air Tank under Maintenance.
NOTICE: Risk of property damage. Place engine fuel valve lever
(M) in the OFF position before moving or transporting unit.
WARNING: Risk of bursting. Drain air tank daily. Water will
condense in air tank. If not drained, water will corrode and weaken
the air tank causing a risk of air tank rupture.
6. Allow the compressor to cool down.
7. Wipe air compressor clean and store in a safe, non freezing area.
