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 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. You can connect an accessory to either the direct outlet
valve (4) and/or the regulated outlet valve (7). The
regulated outlet is the one on the left when you face
the front of the compressor.
4. The pressure of the
regulated outlet [as shown
on the regulated outlet
pressure gauge (8)] can
be changed by turning the
regulating knob (6).
Rotate the knob clockwise
to increase pressure and
anti-clockwise to decrease
pressure.
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.
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.
The discharge air from the right hand (opposite) outlet
(4) is not regulated and will discharge air at tank
pressure. The gauge for this outlet (5) will show the
correct pressure in the tank with or without the air being
discharged.
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 tank 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 (9) 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.
