4. To stop the compressor, lift the On/Off lever (3) to the 

vertical position.

Operation

1. The pressure in the tank is controlled by the action of 

the pressure switch located under the pressure switch 

cover (2). When the set maximum pressure is reached 

the pressure switch activates and the motor is switched 

off. The pressure then decreases as the air is used by the 

connected tool until the set minimum pressure is reached 

after which the pressure switch causes the motor to 

switch on again. The operator of the compressor should 

be well aware that during use of the compressor the 

motor will start and stop under the influence of the rising 

or falling pressure in the tank. The motor will start without 

any warning.

2. The maximum and minimum pressures are factory set 

and the operator should not try to change them.

3. All accessories are connected to the regulated air  

outlet (6). 

4. The pressure of the regulated 

outlet, as shown on the 

regulated outlet pressure 

gauge (7), can be changed  

by turning the regulating  

knob (5). 

Note. 

To obtain the correct 

output reading on the regulated 

output gauge, the air must be 

flowing through the outlet.
The regulating valve should be adjusted and the gauge read 

with the outlet valve open and the air being discharged from 

the regulated outlet through the accessory being used.

To increase the air pressure, rotate the regulating valve 

clockwise. To decrease the pressure, rotate the regulating 

valve anti-clockwise.

Note. 

If you do not allow the air to discharge while you 

are setting the regulator, the pressure as indicated on the 

regulated outlet gauge will be incorrect. This gauge ONLY 

indicates the correct pressure while air is being discharged 

from the outlet.
5.  On completion of the task, i.e. when you have finished 

using the compressor, or when you are leaving the 

compressor unattended, turn off the compressor in the 

following way:

• 

Set the on/off lever (3) to the 

off position.

• 

Wait for the pressurised air to 

bleed from the release valve 

under the pressure switch 

cover (2). 

Note. 

You may hear a short air 

discharge for approximately 1/2 

a second. This discharge only 

occurs if the compressor is actually  

running at the time, and not in idle.

• 

Switch off the electrical power supply and remove the 

electrical plug. 

• 

Pull the ring on the safety valve (8) to ensure all the 

pressurised air is released from the tank, or open the 

drain cock (10) to release the pressure from the tank.  

To open the drain cock (10) rotate the valve ant-clockwise 

and to close the valve rotate it clockwise.
