STARTiNG THE COMPRESSOR.
4.3.1. Your compressor is fitted with two push buttons for on/off
switching. to turn the compressor on push the green "on"
button. to turn the compressor off push the red button "off"
downwards. (see fig.5)
4.3.2. check that the on/off switch is in the "off" position.
4.3.3. Plug mains lead into mains supply and start the compressor
by pushing the green "on" button (fig.5) downwards.
4.3.4. leave the compressor running with no air line or tools
connected. make sure that the pressure in the tank rises and
that the compressor stops automatically when the maximum
pressure is reached. this value is written on the specification
plate and may take in excess of 5 minutes.the compressor
will now operate automatically. the pressure switch (fig.5)
stops the motor when the maximum tank pressure is reached
and restarts it when pressure falls below the minimum
threshold approximately 2bar (29psi) less than the maximum
pressure.
4.3.5. stop the compressor by pushing the red "off" button (fig.5)
downwards. the compressed air inside the compressor head
will flow out via the air line tube situated beneath the switch
housing. restart is made easier and prevents 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.
note: 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.
should the pressure in the main tank exceed the pre-set
switch (fig.5) maximum, the safety valve (fig.1) will activate.
WARNiNG! For this reason dO NOT tamper with, or
adjust, the switch or safety valve.

MAiNTENANCE
In order to keep the compressor in good working condition,
periodic maintenance is essential.
WARNiNG! Before performing any maintenance
operation, switch off the compressor, disconnect from
electricity supply and release all air from the tank.
iMPORTANT! Failure to carry out maintenance tasks may
invalidate the warranty on your compressor.
5.1.
oPerAtIons to Be cArrIed out After tHe fIrst
5 WorKInG Hours:
a) check that all bolts/nuts are tight, particularly those
retaining the crank case and cylinder head.
5.2.
oPerAtIons to Be cArrIed out After tHe fIrst
50 WorKInG Hours:
b) replace the lubricating oil - see para 5.5.
5.3.
oPerAtIons to Be cArrIed out dAIlY:
a) drain condensation by opening the valve located under
the tank (fig.5). Place a container under the valve and slowly
open the valve by turning counterclockwise.
5.4.
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 elements (see fig.8) and clean with
compressed air (Wear eye protection). dO NOT operate the
compressor without the filters as foreign bodies or dust could
seriously damage the pump.
c) check for oil leaks
5.5.
oPerAtIons to Be cArrIed out eVerY 200 Hours:
a) replace the lubricating oil. for oil specifications see 5.7.
remove the oil filler plug (see fig.4.B) then unscrew oil drain
plug (see fig.4) and drain 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 oil drain plug and refill through the oil filler
aperture. do not overfill. replace oil filler plug.
b) Check the automatic cut-out at max. pressure and the
automatic cut-in at 2bar below.
WARNiNG! Never mix different oils and dO NOT use
non-detergent/low quality oils as the compressor may be
damaged.
WARNiNG! dispose of waste oil only in accordance with
local authority requirements.
5.6.
oPerAtIons to Be cArrIed out eVerY 500 Hours:
a) replace air filter. (see fig.7)
b) check all tube fittings and electrical connections.

5.8
iMPORTANT 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.
Please note that any parts damaged by any type of
contamination will not be covered by warranty.

inspection of pressure tank both inside and out.
under the Pressure sYstems sAfetY reGulAtIons
2000 it is the responsibility of the owner of the compressor to
initiate a system of inspection that both defines the frequency
of the inspection and appoints a person who has specific
responsibility for carrying out the inspection.
