General Warnings and Cautions
Warning:
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired. In particular, excessive moisture may impair operation.
The equipment is for indoor use only. The equipment is not designed for use in an explosive atmosphere.
Where a Warning symbol appears on the product (e.g. finger trap warning), users must consult this manual to
ascertain the nature of the potential hazard and the means of avoiding them.
When using the compressor, keep it out of reach of children, never leave it unattended and not direct air stream
towards persons.
When a flammable liquid is sprayed, there may be danger of fire or explosion, especially in closed rooms: Ensure
the area is ventilated adequately.
Do not repair the compressor while it is connected to the electric circuit or when the tank is under pressure.

While running, the motor / air hose unit reaches a high temperature. If working near this unit do not touch.
Warning
Do not dispose of collected condensate down drain as it contains some oil. Refer to local regulations.
Warning
When properly installed, the compressor should work with a duty cycle of less than 50%. If there are air leaks
in the system, the compressor may work more than this, causing excess heating and auto-shutdown via the
thermal cut-out protection circuit. If this happens, the system should be checked and air leaks fixed, before
continuing.
