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.
