Operation Instructions - Surtek COMP550A Manual De Usuario

3. Open the regulated output valve. Open the
valve by rotating the air tap so it is in line with
the air outlet (refer to Fig.7 OPEN). To close the
valve, rotate the air tap so it is facing to the
right or the left side of the air valve (refer to
the CLOSED picture).
4. Start the compressor by following the pro-
cedure in the section "To start and stop the
compressor".
For the first time of operation, run the com-
pressor for 10 minutes with no load and with
the outlet valve open to ensure all parts are
well lubricated.
WARNING: Be aware that pressurised air
will be discharged from the outlet and care
should be taken that this discharge is not di-
rected towards you the operator, or other per-
sons within the area.
TO START & STOP THE COMPRESSOR
1. Check the rating label on the compressor in-
dicates 120 V.
2. Plug in the mains cable of the compressor to
a standard 120 V household power point and
turn on.
3. To start the compressor, lift the ON/OFF
switch on the pressure switch cover (Fig.8).
4. To stop the compressor, push the ON/OFF
switch down (Fig. 9).

OPERATION INSTRUCTIONS

1. The pressure in the tank is controlled by the
action of the pressure switch located under
the pressure switch cover. When the set maxi-
mum 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
14

OFF
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 regu-
lated outlet valve.
4. The pressure of the
regulated outlet, as
shown on the regulated
outlet pressure gauge,
can be changed by turn-
ing the regulating knob
(Fig.10).
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 regulat-
ing 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 pres-
sure as indicated on the regulated outlet
gauge will be incorrect. This gauge ONLY in-
dicates 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.
• Wait for the pressurised air to bleed from the
release valve under the pressure switch cover.
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 re-
move the electrical plug.
• Pull the ring (Fig.11)
on the safety valve to
ensure all the pres-
surised air is released
from the tank, or open
the drain cock to re-
lease the pressure from
the tank.
