3. PREPARAtiON & ASSEMBLY
3.1. remove compressor from packaging and inspect for any
shortages or damage. If anything is found to be missing or
damaged contact your supplier.
3.2. confirm that the mains voltage corresponds with the voltage
shown on the compressor data plate.
3.3. the compressor should be installed on a flat surface, or one
that does not exceed 10° either transversely or longitudinally,
(see fig.1) and should be in a position that allows good air
circulation around the unit.
3.4. iMPORtANt! Check that the oil in the pump is level with
the centre of the sight glass (fig.2C). if not remove the oil
filler/breather from the pump (fig.2B) and fill with oil.
Replace the filler/breather.

3.5
Ensure that the air vent in the oil filler/breather is free
from debris. if the air vent is blocked, pressure can build
up in the crankcase causing damage to the compressor
and possible personal injury.
3.6.
screw air filter (fig.2A) into inlet port.

4. tOOL SELECtiON
iMPORtANt 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 - and so it is
important that, before choosing equipment, you study
the 'Free Air delivery' figures shown in the Specification
Chart.

iNStRUCtiONS.
5.1.
make sure that the main switch (fig.3.1) is 'off' (down).
5.2.
check the oil level by looking through the sight glass
(fig.2c).
5.3.
ensure that the tank drain valve is closed (fig.5).
5.4.
close the outlet pressure regulator by turning the knob
clockwise (fig.3.2).
5.5.
connect the air tool required to the compressor via an air line
connected to the air outlet. open the tap on the air outlet so
that the handle is in line with the air flow (fig.3.4).
5.6.
Plug the mains cable into the mains supply and start the
compressor by pulling up the main switch.
5.7.
Allow the pressure in the tank to rise to the maximum at
which point the compressor will automatically cut out. tank
pressure is shown on the larger gauge (fig.3.6).
5.8.
Begin to gradually open the regulator by turning the knob
clockwise until the small gauge registers the required
operating pressure specified for the tool to be used. Always
adjust up to the required pressure rather than down from a
higher pressure. the required setting, once achieved, can be
locked by screwing the locking ring (fig.3.3) up tight
underneath the adjusting knob.
5.9.
You can now begin to use the tool. the compressor will
operate automatically cutting in and out as required to
restore the air pressure in the tank. 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. 2bar (29psi) less than the
maximum pressure.
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 appliance.

b) the main gauge (fig.3.6) indicates the pressure inside the
main tank, NOt the pressure supplied to the air equipment,
which is shown on the smaller gauge (fig.3.5). 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 the safety valve.
When the compressor is not being used set the regulated
pressure to zero so as to avoid damaging the pressure
regulator.
5.10. to stop the compressor press down the main switch (fig.3.1).
When the compressor stops there will be a whistling sound
as compressed air is vented from the compressor head.
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.
5.11. When you have finished using the compressor unplug the
unit from the mains power supply.
5.12. set the outlet pressure on the regulator to zero.
5.13. remove the air line and air tool.
5.14. the tank must now be drained. this will release the air left in
the tank and drain away condensation that may have formed
within the tank. choose a suitable location for this operation
and/or make provision to collect the condensation. Wear ear
and eye protection. open the tank drain valve (fig.5)
slowly allowing air and moisture to bleed from the tank. After
bleeding close the drain valve to prevent debris building up in
the valve.
WARNiNG! Water that is allowed to remain in the tank
during storage will corrode and weaken the air tank
which could cause the tank to rupture. to avoid serious
injury drain the tank after each use or daily.
5.15. SAFEtY FEAtURES
thermal cut out: If the unit overheats the thermal cut out
will operate and shut the unit down. the thermal cut out will
automatically reset when the unit has cooled down which
may take up to 30 minutes.
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, periodic maintenance is
essential.
6.1.
After the first 50 working hours replace the lubricating
oil - see paragraph 6.4.

6.2.
OPERAtiONS tO BE CARRiEd OUt dAiLY:
fig.3
a) drain condensation by opening the valve located under
the tank. Place a container under the valve and open the
valve by turning anti-clockwise. see fig.5.
b) check that all bolts/nuts 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):
a) check oil level and, if necessary, top up.
b) remove the filter element (fig.4) and clean by blowing
through with an air line at low pressure, from the clean side.
Alternatively, wash in soapy water, rinse and dry. dO NOt
operate the compressor without the filter as foreign bodies or
dust could seriously damage the pump.
c) check for oil leaks.
6.4.
OPERAtiONS tO BE CARRiEd OUt EvERY 200 HOURS:
a) replace the lubricating oil. for oil specifications see
below. remove the oil filler plug (fig.2B) and unscrew sight
glass (fig.2c), draining the oil into a container. drain when the
compressor is hot so that oil drains rapidly and completely.
Incline compressor to ensure complete drainage. replace
sight glass and refill through the filler aperture. dO NOt
overfill. replace plug (fig.2B).
recommended oil for compressors, suitable for room
temperatures ranging from +5ºc to +25ºc. seAleY cPo/1,
cPo/5 or equivalent sAe 40 compressor oil.
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. dispose of waste oil only in accordance with
local authority requirements.
b) check the automatic cut-out at max. pressure and the
automatic cut-in at 2bar below.
6.5.
OPERAtiONS tO BE CARRiEd OUt EvERY 500 HOURS:
a) replace air filter.
b) check all tube fittings and electrical connections.
c) Inspect pressure tank inside and out for damage or
corrosion.
iMPORtANt! Failure to carry out maintenance tasks may
invalidate the warranty on your compressor.
