7
must be checked by qualified personnel only.
dO NOt use the compressor outdoors, or in damp, or wet,
7
locations.
dO NOt operate within the vicinity of flammable liquids,
7
gases or solids.
dO NOt touch compressor cylinder, cylinder head or pipe
7
from head to tank as these may be hot.
dO NOt use this product to perform a task for which it has
7
not been designed.
dO NOt deface the certification plate attached to the
7
compressor tank.
dO NOt cover the compressor or restrict air flow around the
7
unit whilst operating.
dANGER! dO NOt direct the output jet of air towards
q
people or animals.
dO NOt operate the compressor without an air filter.
7
dO NOt allow anyone to operate the compressor unless
7
they have received full instructions.
WARNiNG! the air tank is a pressure vessel and the
following safety measures apply:
dO NOt tamper with the safety valve, dO NOt modify or alter
7
the tank in any way and dO NOt strap anything to the tank.
dO NOt subject the tank to impact, vibration or to heat and
7
dO NOt allow contact with abrasives or corrosives.
WARNiNG! If an electrical fuse blows, ensure it is replaced
with an identical fuse type and rating.
When not in use, store the compressor carefully in a safe,
3
dry, childproof location.

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 the oil in the pump is up to the
centre of the sight glass (fig. 2C). if not, remove the oil
filler/breather (fig.2B) and fill up with oil. Replace the
filler/breather.

tHiS HAS BEEN dONE.
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 (see
fig.2c)
5.3.
ensure that the tank drain valve is closed. (see fig.5)
5.4.
close the outlet pressure regulator by turning the knob
clockwise. (see 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. see 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
anticlockwise 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 (see 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. 2 bar (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.
