2. Pull the regulator knob (D) out and turn counterclockwise until fully
closed. Ensure regulated pressure gauge reads 0 psi. Push knob
in to lock in place.
3. Remove hose and accessory.
WARNING: Risk of unsafe operation. Firmly grasp air hose in hand
when installing or disconnecting to prevent hose whip.
4. Drain the air tank,
see Draining Air Tank under Maintenance
.
Ensure air tank pressure gauge reads 0 psi.
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.
5. Allow the compressor to cool down.
6. Wipe air compressor clean and store in a safe, non-freezing area.
The following procedures must be followed when maintenance or
service is performed on the air compressor.
1. Ensure Auto/Off switch is in the OFF position.
2. Remove air compressor plug from outlet.
3. Drain air tank.
4. Allow air compressor to cool down before starting service.
NOTE: All compressed air systems contain maintenance parts (e.g.,
oil, filters, separators) that are periodically replaced. These used parts
may contain substances that are regulated and must be disposed of in
accordance with local, state, and federal laws and regulations.
NOTE: Take note of the positions and locations of parts during
disassembly to make reassembly easier.

WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. NOTE: Ring may
be difficult to pull when air tank pressure is at 0 psi. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.
