requires 110V. Pump head directly coupled to heavy-duty induction 

motor for reliable and quiet operation. Welded tank complies with 

latest european standards. fitted with fully automatic pressure 

cut-out switch with twin gauges displaying tank and working 

pressures. fitted with Bs en 60309 approved 16Amp 110V plug.

 

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.

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.

with an identical fuse type and rating.

  

3

  When not in use, store the compressor carefully in a safe,  

 

dry, childproof location.

3

  When the compressor is not in use it should be switched off,  

 

disconnected from the power supply and the air drained from  

 

the tank.

3.  PREPARAtiON & ASSEMBLY

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.

 

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.

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).

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.

 

  

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.

 

 

fig.3

 

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
