4. To stop the compressor, push the On/Off switch down.
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
outlet valve (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:
• Press down the on/off switch (3).
• Wait for the pressurised air to bleed from the release
valve under the pressure switch cover (2).
NOTE. When you press the button down you should hear
a short air discharge (Approx 1/2 second).
• 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 to release the
pressure from the tank.
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 button is pressed
down, 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 (17).
