WARNINGS
Avoid unscrewing any connection parts without first relieving the pressure in the device and tank
as well as the pipes.
It is forbidden to drill holes or weld or intentionally deform the compressed air tank.
Always unplug the compressor before carrying out any work on the compressor!
The ambient temperature for proper operation must be between 0°C and +25°C.
Do not spray the compressor with water jets or flammable liquids.
Do not place any flammable objects near the compressor.
Set the push button and power button to "OFF" when pauses are made or the unit is not in use.
Never aim the air jet at people or animals.
Never transport the compressor as long as there is pressure in the tank.
Make sure that some parts of the compressor (head, pressure hoses) can become very hot. Do
not touch these parts as there is a risk of burns!
When transporting the device, make sure that you only use the handles and handles provided for
lifting and pulling the device.
Children and animals must be kept away from the operating area of the machine.
If the power cable or plug is damaged, do not use the compressor. Contact the manufacturer or an
authorized service partner.
If the compressor is placed on a shelf or higher than the floor, it must be secured against falling
during operation by means of a suitable fastening.
Do not push any objects into the protective grilles and do not reach in with your hands as this may
cause injury to the user or damage to the device.
Always disconnect the mains plug after using the compressor!
