4. PREPARATION
4.1. Remove compressor from packaging and inspect for any shortages or damage. If anything
is found to be missing or damaged contact your supplier.
4.2. Save the packing material for future transportation of the compressor. We recommend
that you store the packing in a safe location, at least for the period of the guarantee. Then,
if necessary, it will be easier to send the compressor to the service centre.
4.3. Confirm that the mains voltage corresponds with the voltage shown on the compressor
data plate.
4.4. Assemble the wheels (fig.A.X) and rubber feet (fig.A.Y) to the main frame using the nuts,
bolts and washers supplied.
4.5. Attach handle with screw provided.
4.6. The compressor should be operated on a flat surface, or one that does not exceed 10°
either transversely or longitudinally (fig.1), and should be in a position that allows good air
circulation around the unit.
4.7. Remove the plastic transit plug from the oil filler hole.
4.8. Before using the compressor check the oil level by referring to the oil sight glass (fig.2C).
If the oil level is not up to the red centre mark it should be further topped up with
recommended oil (See section 6.7). Screw the filler/breather cap into the aperture as
shown in fig.2B.
4.9. Screw the back half of a filter unit into the downward facing port openings in each head as
shown in fig.2A. Place a filter cover over each threaded rod protruding from the back half
of the filter and secure each with a wing nut. Refer also to fig.4.
5. OPERATION
WARNING! Ensure that you have read, understood and apply Section 1 safety instructions.
5.1. IMPORTANT. The use of extension leads to connect this compressor to the mains is not recommended as the resulting voltage
drop reduces motor, and therefore pump, performance and could damage your compressor.
5.2. Take care when selecting tools for use with the compressor. Air tool manufacturers normally express the volume of air
required to operate a tool in cubic feet per minute (cfm).
This refers to free air delivered by the compressor (‘air out’) which varies according to the pressure setting. DO NOT
confuse this with the compressor displacement which is the air taken in by the compressor (‘air in’). ‘Air out’ is always less
than ‘air in’ - due to losses within the compressor.
5.3. STARTING THE COMPRESSOR.
5.3.1. Your compressor is tted with a push/pull type of ON/OFF switch. To turn the compressor ‘ON’ pull the switch knob upwards. To turn
the compressor ‘OFF’ push the knob downwards. (See g.3.1)
5.3.2. Check that the ON/OFF switch is in the “OFF” position, the regulator tap (fig.3.2) is closed (Zero ‘0’ bar), and air tap (g.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 (g.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 g.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.
5.3.7. The compressor is fitted with a reset trip, located in the connection box on top of the motor (see 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 6.3.
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). Retighten 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 +5ºC to +25ºC: SEALEY CPO or
equivalent SAE 40 compressor oil.
6.5.2. Room temperature below +5ºC: 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 a󰀨ect optimum performance. Example: Body ller dust or paint overspray
will clog the pump intake lter and may cause internal damage to pump/motor components.
NOTE: Any parts damaged by any type of contamination will not be covered by warranty.
