5.3.2.
Check that the ON/OFF switch (fig.3.1) is in the “OFF” position, the regulator
tap (fig.3.2)
is closed (Zero ‘0’ bar), and air tap (fig.3.4) is OFF.
5.3.3.
Plug mains lead into mains supply and start the compressor by pulling the switch
knob upwards.
5.3.4.
When starting the compressor for the first time, leave it running for several minutes
with the air
tap (fig.3.4)
open to ensure good distribution of the lubricating oil.
Turn the compressor off and close the air tap. Restart the compressor and
leave it running with air tap (fig.3.4) closed and regulator (fig.3.2) set to
maximum pressure. Make sure that pressure in the tank rises and that the
compressor stops automatically when the max. pressure value allowed - written on
the specification
plate and shown on the gauge (fig.3.6) - is achieved.
The compressor will now operate automatically. The pressure switch(fig.3.8)
stops the motor when the maximum tank pressure is reached and restarts
it when pressure falls below the minimum threshold - approx. 2 bar (29psi) less
than the maximum pressure.
5.3.5.
Stop the compressor by pushing the switch knob
(See fig.3.1)
downwards. The
compressed air inside the compressor head will flow out, making the restart easier
and preventing the motor from being damaged.
DO NOT
, other than in an
emergency, stop the compressor by switching off the mains power, or by pulling
the plug out, as the pressure relief will not then occur and motor damage may
result upon restart.
When the compressor runs correctly and is stopped correctly there will be:
a)
a whistle of compressed air when the motor stops,
b)
a protracted whistle (about 20-25 seconds) when the compressor starts with no pressure in the tank.
5.3.6.
The output pressure is regulated by the pressure regulator (fig.3.2). Turn the knob clockwise to increase pressure and clockwise to
reduce it. The knob can be locked at any required setting by tightening the locking ring (fig.3.3) up against the underside of the knob.
To determine the correct working pressure for any piece of equipment check the corresponding manual. When the compressor is not
being used set the regulated pressure to zero so as to avoid damaging the pressure reducer.
NOTE:
a)
If the motor does not cut in and out, but runs continuously when using an air appliance, the capacity of the compressor
may be too small for the equipment or tool.
b)
The larger gauge (fig.3.6) indicates the pressure inside the main tank. The smaller
gauge (fig.3.5) indicates the pressure supplied to the air equipment. Should the pressure in the main tank exceed the pre-set switch
(fig.3.8) maximum, the safety valve (fig.3.7) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the switch or safety valve.
5.4.
The compressor is fitted with a reset trip, located in the connection box on top of the motor (fig.A.Z). The reset button is on the side
of the box. Should the trip activate, leave for 1 minute before pressing the button to reset. For possible causes of trip activation and
remedies see section 7 Troubleshooting.
6. MAINTENANCE
WARNING!
Before performing any maintenance operation, switch off the
compressor, disconnect from electricity supply and release all air from the tank. In
order to keep the compressor in good working condition, periodical maintenance
is essential.
6.1.
After the first 50 working hours replace the lubricating oil - see Item 6.4.
6.2.
OPERATIONS TO BE CARRIED OUT DAILY:
6.2.1.
Drain condensation, place a container under the valve and open the valve by
turning anti-clockwise (fig.5). Re-tighten the valve.
6.2.2.
Check that all nuts and bolts are tight, particularly those retaining the crankcase
and cylinder head.
6.3.
OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS:
(or more frequently, if the compressor operates in a very dusty atmosphere).
6.3.1.
Check oil level and, if necessary, top it up.
6.3.2.
Remove the air filter element by unscrewing the filter holder (fig.4) and prising open the holder. Clean it by blowing through with an air
line at low pressure, from the clean side. Alternatively, wash it in soapy water, rinse and dry.
DO NOT
operate the compressor without
the filter as foreign bodies or dust could seriously damage the pump.
6.3.3.
Check for oil leaks.
6.4.
OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
6.4.1.
Replace the lubricating oil. Remove the oil filler/breather (fig.2A) and unscrew the drain bolt (fig.2B), drain
the oil into a suitable container. Drain when the compressor is hot so that the oil drains rapidly and
completely. Incline the compressor to ensure complete drainage. Replace the drain bolt and refill with fresh
oil through the filler aperture.
DO NOT
overfill.
6.4.2.
Replace oil filler/breather (fig.2A).
6.5.
RECOMMENDED OIL:
6.5.1.
Suitable for room temperatures ranging from +5
º
C to +25
ºC: SEALEY CPO or equivalent SAE 40
compressor oil.
6.5.2.
Room temperature below +5
ºC: SAE 20 compressor oil.
WARNING! Never mix different oils and DO NOT use non-detergent/low quality oils as the compressor may be damaged.
6.5.3.
Dispose of waste oil only in accordance with local authority requirements.
6.5.4.
Check the automatic cut-out at maximum pressure and the automatic cut-in at 2 bar below that.
6.6.
OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:
6.6.1.
Replace air filter (fig.4).
6.6.2.
Check all tube fittings and electrical connections.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
WARNING
- Air contaminants taken into the compressor will affect optimum performance. Example: Body filler dust or paint
overspray will clog the pump intake filter and may cause internal damage to pump/motor components.
NOTE:
Any parts damaged by any type of contamination will not be covered by warranty.
