Please read theentire instruction manual before using theproduct and then save it for future
reference. Wereserve theright for any errors in text or images and any necessary changes
made to technicaldata. Intheevent of technical problems or other queries, please contact our
Customer Services (see address details on theback).
Safety
• Always use ear defenders and safety goggles when using thecompressor.
• Reduce therisk of electric shocks. Avoidbody contact with earthed objects such as water
pipes and radiators.
• Use aface mask for dustywork.
• Never use thecompressor in areas where flammable liquids/materials or gases (petrol,
solvents, gas cylinders) are stored orused.
• Never switch thecompressor off by pulling out theplug, always use theON/OFF button.
• Always unplug themains lead and empty thepressure vessel of air before servicing or
repairing thecompressor.
• Always unplug themains lead and empty thepressure vessel of air before moving
thecompressor.
• Make sure that themains lead does not come into contact with heat, oil, or sharpedges.
• Never move thecompressor around by pulling themains lead or airhoses. Thecompressor
must only be moved using thehandle.
• If themains lead is damaged, to prevent any risk of fire or electrocution, it must only be
replaced by aqualified electrician.
• Make sure that any air hoses and air tools connected to thecompressor are rated to
withstand thepressure generated by thecompressor and that they are connected correctly.
• This product must not be used by anyone (including children) suffering from physical
or mental impairment. Thisproduct should not be used by anyone that has not read
theinstruction manual unless they have been instructed in its use by someone who will take
responsibility for their safety.
• Never let children play with theproduct.
• Do not weld or in any way modify thepressure vessel.
• Never aim compressed air at yourself or any other person.

Product description
Thecompressor increases thepressure of theair which is pumped into thepressure vessel.
Whentheair pressure in thevessel reaches max, apressure switch switches off themotor driving
thecompressor. Atthesame moment, theair in thecompressor is released. Thisoccurs to
reduce thepressure in thecompressor so that it can restart when thepressure drops to below
theminimum pressure. Asafety valve releases theair in thepressure vessel if thepressure switch
should fail to turn themotoroff.

Getting started
1. Attach thewheels, rubber feet and air filter.
Before using theair compressor for thefirst time:
Open thedrain tap (6) in thebottom of theair tank, switch thecompressor on
(by pulling thebutton of theON/OFF switch (7) up) and let it run for 10 minutes to
lubricate all themovingparts. Closethedraintap.
2. If the oil inlet (4) is fitted with a transit bung,
remove it and replace it with the proper oil
filler cap.
3. Pour approximately 400 ml oil into the oil
inlet and fit the proper oil filler cap. Check
the oil level through the oil level window (5).
4. Placethecompressor in aclean, dry and
well-ventilated location.
5. Makesure that it is stable and cannot
tipover.
6. Makesure that theoil level is up to thered
circle in theoil level window (5).
7. Connect themains lead to a230 V wall
socket.

Instructions for use
1. Check theoil level in thewindow (5).
2. Attach theappropriate air tool for thework you wish to undertake: blow gun, spray gun, tyre
inflator, etc.
3. Read theinstruction manual of theconnected air tool and if necessary, set therecommended
working pressure using thepressure regulator (10).
4. When you have finished work and thecompressor has been turned off, thepressure must be
released by pulling out thesafety valve (12).
Use anoil suitable for air compressors such as SAE 30, ISO 68 or equivalent.
Care and maintenance
• Repairs must only be carried out by qualified service technicians and only using original spare parts.
• An initial replacement of theoil in theair compressor should be carried out after 10 hours of
operation.
• Change theoil and clean theair filter after every 120 hours ofuse. Checkthesafety valve and
pressure gauges at thesametime.
• Test thesafety valve by unscrewing theuppermost nut until it is loose and then pulling it out
until thespring-loaded valveopens. Ifthesafety valve is working properly (and theair tank
is under pressure) air should seep out through thesafetyvalve. Oncethevalve has been
tested, screw theuppermost nut back inagain.
• Perform avisual inspection at least once ayear to check that theinside and outside of theair
tank is free of corrosion. Underno circumstances must thewall thickness of theair tank be
less than 2mm.
• Under no circumstances must thesafety valve be tampered with or blocked.
• Regularly check that theventilation hole in theoil filler cap (4) isopen.
• Regularly check that all bolts holding thecompressor and air tank together aretight.
• Make it ahabit to open thedrain tap (6) and release any condensation inside theairtank.
• Do not clean thecompressor or air tank with solvents or flammable liquids.
• If thecompressor is not to be used for along time: Unplug themains lead, empty theair tank
Motor overload cut-out
• If thesafety cut-out has tripped, themotor has been overloaded in
some way.
• Thebutton on themotor overload cut-out (1) will pop out acouple of
millimetres when it has been tripped and is reset by pushing it back in.
• There are anumber of possible reasons why theoverload cut-out
might trip such as avoltage drop caused by theuse of long exten-
sion leads, low ambient temperature (under10°C), or that thepres-
sure switch is not used to turn thecompressor on/off in theevent of
apower cut for example.

and open thedrain tap (6).
Changing the oil
1. Before changing theoil, make sure that theair compressor is switched off and unplugged
from thewall socket.
2. Remove theoil filler cap from theoil inlet (4).
3. Tilt thecompressor so that oil can run out of theoil filler hole into anappropriate receptacle.
4. Let theoil completely drain from thecompressor.
5. Replace with new oil until theoil reaches themiddle of theoil-display window. Refittheoil
fillercap.
• Oil requirement, approx. 400 ml (not included).
• Use anoil suitable for air compressors such as SAE 30, ISO 68 or equivalent. Compres-
sor oil is especially designed for compressors, amongst other things it has additives that
prevent foaming. Ifno compressor oil is available then SAE 10–30 engine oil can be used as
asubstitute.
Troubleshooting guide
Thecompressor
does not start.
• Is it plugged into awall socket?
• Is thewall socket live?
• Has themotor’s overload protection tripped? Reset by pushing in
thebutton (1).
• Is themains lead damaged?
Heavy vibrations
and/or unusual
sounds.
• Check that all bolts holding thecompressor and pressure vessel
together are tight.
• Check all other joints and connections.
No pressure build-
up in vessel or
pressure too low.
• Make sure thesafety valve is not leaking.
• Make sure thedrain tap is not leaking.
• Check all hose connections for leaks.
• Air filter is clogged.
Oil consumption
too high.
• Too much oil in thecompressor.
• Theventilation hole in theoil filler cap is clogged.
