3. PREPARAtION
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. save the packing material for future transportation of the compressor. We recommend that the
packing is stored in a safe location, at least for the period of the guarantee. then, if necessary,
it will be easier to send the compressor to the service centre.
3.3. confirm that the mains voltage corresponds with the voltage shown on the compressor data
plate.
3.4. fit the main wheels and the rubber foot to the main frame using the nuts, bolts and washers
supplied (fig.1).
3.5. the compressor should be installed on a flat, firm surface, or one that does not exceed 15°
either transversely or longitudinally, and should be in a position that allows good air circulation
around the unit.
 DO NOt attempt to move the compressor by pulling the air tool hose. only move the compressor by the handle.
 DO NOt use this product to perform a task for which it is not designed.
 DO NOt deface the certification plate attached to the compressor tank.
 DO NOt cover the compressor or restrict air flow around the machine whilst operating.
 DO NOt operate the compressor without an air filter.
 DO NOt allow anyone to operate the compressor unless they have received full instructions.
 DANGER! DO NOT direct the output jet of air towards people or animals.
 WARNING! The air tank is a pressure vessel and the following safety measures apply:
 DO NOT tamper with the safety valve and DO NOT modify or alter 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 DO NOT allow contact with abrasives or corrosives.
 DO drain condensation from tank daily and inspect inside walls for corrosion every three months and have a detailed tank
inspection carried out annually.
 The tank shell must not fall below the certified thickness at any point.
 WARNING! If an electrical fuse blows, ensure it is replaced with an identical fuse type and rating.
 When not in use for a long period, store the compressor carefully in a safe, dry, childproof location.
 When the compressor is not in use, it should be switched off, disconnected from the
mains supply and the air drained from the tank.
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.

4.1. IMPORtANt. the use of extension leads to connect this compressor to the mains is not recommended as the resulting voltage drop
reduces motor, and therefore pump, performance.
4.2. 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 .

4.3. StARtING tHE COMPRESSOR.
4.3.1. the compressor is fitted with a push on/off switch (fig.2).
to turn the compressor ‘on’ push the switch. to turn the compressor ‘off’ push
the switch again.
4.3.2. check that the on/off switch is in the “off” position and the regulator tap
(fig.2) is closed (Zero ‘0’ bar, Anti-clockwise).
4.3.3. Plug mains lead into mains supply and start the compressor by pushing the
on/off switch.
4.3.4. leave the compressor running with the regulator tap (fig.2) set to maximum
pressure. make sure that the pressure in the tank rises and that the compressor
stops automatically when the maximum pressure value allowed - written on the
specification plate is achieved. the compressor will now operate automatically.
the pressure switch stops the motor when the maximum tank pressure is reached,
and will restart it when pressure falls below the minimum threshold - approx. 2 bar
(29psi) less than the maximum pressure.
4.3.5. stop the compressor by pushing the on/off switch (fig.2). the compressed air inside the compressor head will flow out, making the
restart easier and preventing the motor from being damaged.
DO NOt, other than in an emergency, stop the compressor by switching off the mains socket, or by pulling the plug out of the socket,
as the pressure relief will not then occur and motor damage may result upon restart.
4.3.6. the output pressure is regulated by the pressure regulator tap (fig.2). turn the tap clockwise to increase pressure and anti-clockwise to
reduce it, view the result on the output regulator gauge (fig.2)
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 equipment or tool.
b) should the pressure in the main tank exceed the pre-set switch maximum, the safety valve (located under the motor cowling
adjacent to the regulator gauge) will activate.
 WARNING! For this reason DO NOt tamper with, or adjust, the pre-set switch or safety valve.
