Shutdown
Procedure
When you are finished using the compressor:
1. Move the pressure switch to the OFF position.
2. Operate tool briefly to release system pressure.
3. Disconnect all tools.
4. Drain air receiver tank by pulling safety relief
valve.
5. After all air is discharged from receiver tank,
disconnect the hoses.
6. Once the tank pressure gauge registers under 10
PSI, open the tank drain valve on the bottom of
the tank to drain condensation. Leave tank drain
open until next use.
WARNING: Risk of bursting
Drain air receiver tank daily or after each use to prevent
moisture buildup in the air tank. Serious injury or death
may occur from a tank explosion caused by moisture
induced tank corrosion.
For Malfunction During Operation
Immediately turn off the compressor if any of the
following conditions arise during operation:
Excessive change in motor speed, slow or fast
Overheating
Excessive vibration
Unusual noise
Flame or smoke
Air leakage
Pull ring on safety valve to immediately relieve pressure.
WARNING: Shutdown hazards
Do not leave an operating machine unattended. Always
shut the machine OFF and relieve the pressure before
leaving the machine. NEVER disconnect the high-
pressure outlet hose from the unit while the tank and air
line are pressurized. A hazardous high pressure air
stream will result as receiver tank is quickly emptied.
