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. OPERATION
 WARNING! ENSURE THAT YOU HAVE READ,
UNDERSTOOD AND APPLIED SECTION 1 SAFETY
INSTRUCTIONS.
5.1. Make sure that the main switch (fig.5.1) is ‘OFF’ (down).
5.2. Check the oil level by looking through the sight glass (fig.3).
5.3. Ensure that the tank drain valve is closed (fig.1).
5.4. Connect the air tool required to the compressor via an air line
connected to the air outlet.
5.5. Plug the mains plug into the mains supply and start the
compressor by pulling up the main switch (fig.5.1).
5.6. 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.5.6).
5.7. Begin to gradually open the regulator by turning the knob
clockwise (fig.5.2) 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.5.3) up tight
underneath the adjusting knob.
5.8. 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.5.8) 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.5.6) indicates the pressure inside the
main tank, NOT the pressure supplied to the air equipment,
which is shown on the smaller gauge (fig.5.5). Should the
pressure in the main tank exceed the pre-set switch (fig.5.8)
maximum, the safety valve (fig.5.7) will activate.
WARNING! For this reason DO NOT tamper with, or
adjust, the switch or the safety valve.
2. INTRODUCTION & SPECIFICATION
Model features aluminium cylinder head with cast iron cylinder giving
added resistance to wear over time. Suitable for general purpose
workshop applications. Pump head directly coupled to a heavy-duty
induction motor for reliable 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 16A 110V plug
3. PREPARATION & ASSEMBLY
3.1. Remove the compressor from its packaging and inspect for
any shortages or damage.
3.2. Confirm that the 110V 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.2) and should be in a position that allows good air
circulation around the unit.
3.4. The compressor is supplied without oil in it. The oil is in a
separate container. Remove the transit plug from the oil filler
aperture, pour oil into the aperture until it has reached the
correct level on the sight glass (fig.3). Fit the oil filler/breather
supplied into the aperture.

To move the compressor, use the handle only. Maintain unit’s
centre of gravity when lifting. DO NOT attempt to lift or move
the compressor by any other means.
3 Use the compressor in a well ventilated area and ensure it is
placed on a firm surface.
3 Keep tools and other items away from the compressor when
it is in use, and keep area clean and clear of unnecessary
items.
3
Ensure the air hose is not tangled, twisted or pinched.
3 Keep children and unauthorised persons away from the
working area.
7 DO NOT disassemble compressor for any reason. The unit
must be checked by qualified personnel only.
7 DO NOT use the compressor outdoors, or in damp, or wet,
locations.
7
DO NOT operate within the vicinity of flammable liquids,
gases or solids.
7 DO NOT touch compressor cylinder, cylinder head or pipe
from head to tank as these may be hot.
7 DO NOT use this product to perform a task for which it has
not been designed.
7 DO NOT deface the certification plate attached to the
compressor tank.
7 DO NOT cover the compressor or restrict air flow around the
unit whilst operating.
q DANGER! DO NOT direct the output jet of air towards
people or animals.
7 DO NOT operate the compressor without an air filter.
7 DO NOT allow anyone to operate the compressor unless
they have received full instructions.
 WARNING! The air tank is a pressure vessel and the
following safety measures apply:
7 DO NOT tamper with the safety valve, DO NOT modify or alter
the tank in any way and DO NOT strap anything to the tank.
7 DO NOT subject the tank to impact, vibration or to heat and
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.
3 When not in use, store the compressor carefully in a safe,
dry, childproof location.

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. If it is not already fitted, screw the air filter holder into the
inlet port (fig.4).
