WARNINGS.

1.Never attempt to remove any part of the compressor whilst the tank is under pressure.

2.Never attempt to remove any electrical component whilst the compressor is connected to the power supply. Switch off the power and remove the electrical plug.

3.Do not adjust the safety valve.

4.Do not use an electrical extension cable.

5.If the release valve under the pressure switch cover (2) fails to operate when the On/Off lever (3) is set in the off position, switch the power supply off and determine the nature of the fault.

6.Ensure that the lubricating oil is clean and that the oil level is maintained at the mid point of the red circle in the oil level glass (16).

7.Take care when discharging air from the tank, i.e. from the safety valve (8), the drain cock (10) or the air outlet (6). Compressed air can be extremely dangerous.

Take care; make sure that the discharge air does not cause dust, stones or any other foreign particles to be blown through the air and that the air is discharged in a safe manner.
