1.2. GENERAL SAFETY INSTRUCTIONS
3Familiarise yourself with the application and limitations of the compressor.
3Ensure the compressor is in good order and condition before use. If in any doubt do not use the unit and contact an electrician/service agent.
p p
WARNING! Compressor must only be serviced by an authorised agent. DO NOT tamper with, or attempt to adjust, pressure switch or safety valve.
3Before moving or maintaining the compressor ensure that it is unplugged from the mains supply and that the tank pressure has been vented.
3Only use recommended attachments and parts. To use unauthorised items may be dangerous and will invalidate your warranty.
3Read the instructions regarding any accessory used with the compressor. Ensure the safe working pressure of any air appliance used exceeds the
compressor output pressure. If using a spray gun, check that the area selected for spraying is provided with air change system/ventilation.
3Ensure the air supply valve is turned off before disconnecting the air supply hose.
3Use the compressor in a well ventilated area and ensure it is placed on a firm surface.
3Keep tools and other items away from the compressor when it is in use and keep area clean and clear of unnecessary items.
3Ensure the air hose is not tangled, twisted or pinched.
3Keep children and unauthorised persons away from the work area.
7DO NOT dis-assemble compressor for any reason. The unit must be serviced by qualified personnel only.
7DO NOT use the compressor outdoors, or in damp, or wet, locations and DO NOT operate within the vicinity of flammable liquids, gases or solids.
7DO NOT touch compressor cylinder, cylinder head or pipe from head to tank as these may be hot and will remain so for some time after shutdown.
7DO NOT attempt to move the compressor by pulling the air tool hose.
7DO NOT use the compressor for a task for which it is not designed.
7DO NOT cover the compressor or restrict air flow around the machine whilst operating.
s s
DANGER! DO NOT direct the air hose towards people or animals.
7DO NOT operate the compressor without inlet air filter.
7DO NOT allow anyone to operate the compressor unless they have received full instructions.
p p
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 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, 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.
p p
WARNING! If an electrical fuse blows, ensure it is replaced with an identical fuse type and rating.
3When not in use, store the compressor in a safe, dry, childproof location.

pWARNING! If an extension lead must be used it should be no longer than 10mtrs and have a 2.5mm2cross section. Using a
excessively long or thin-wired extension cable will cause severe damage to the motor. Always fully unwind extension cables. If using
extension cables outdoors, always use a cable marked for outdoor use. 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. 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, Section 2.
p WARNING! Ensure that you read, understand and apply Section 1 safety instructions.
4.1. Make sure the main switch (fig.1) is in the "Off position.
4.2. Plug the lead into mains supply and start the compressor by pulling the main switch to On (fig.1).
4.3. When starting the compressor for the first time, leave it running with air outlet closed. Make sure that the pressure in the tank rises
and that the compressor stops automatically when the maximum pressure value allowed (written on the plate and shown on the
gauge) is achieved. The compressor will now operate automatically. The pressure switch 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.
4.4. T
o stop the compressor, press the main switch to off (fig.1). 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, as the
pressure relief will not occur and motor damage may result upon restart.
Note: 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. It is recommended that the motor is run continuously for no more than 15 minutes at a time and
allowed 15 minutes to cool down before using again.
4.5. It is possible to adjust the the outlet pressure by turning the regulator knob (Fig.2 clockwise or anticlockwise to respectively increase
or reduce the outlet pressure to the desired level. When the desired outlet pressure is achieved use the locking ring (fig.2) to lock
the pressure regulator to your desired setting.
3.1. Remove compressor from packaging and inspect. 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
you store the packing 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 voltage shown on compressor data plate corresponds with the supply voltage.
3.4. The compressor should be in a position that allows good air circulation around the unit.
2. INTRODUCTION & SPECIFICATION

5. MAINTENANCE
p p
WARNING! Before performing any maintenance operation, switch off compressor, disconnect from power supply and vent air
from tank.
This compressor is oil free and therefore requires no oil in order to operate, this does not however negate the requirement for your air
tools to be lubricated. For details of oiling requirements for your air tools, consult the instruction manual for the individual tool.
5.1 Drain the air tank weekly.
Note: Water in the tank can damage your air tools and produce a poor finish when spraying, it also damages the inside of the receiver tank.
5.1.1 Before draining the water, you must first make sure the air has been discharged from the receiver tank.
5.1.2 To drain the tank simply unscrew the drain valve on the bottom of the receiver tank (fig.3), any water present should then flow out.
As there is no lubrication used the water will not be contaminated and can be disposed of in the sewer system.
5.2 As the compressor is designed for intermittent use the neccesity for cleaning the filter will be reduced. To check the filter and clean it,
remove the screw holding the filter cover and withdraw the filter cover and filter (fig.3). To clean, blow through with an airline.
p p
WARNING! Do not operate the compressor without the filter as this will cause severe damage to the unit.
5.3 To clean the compressor use a damp cloth and mild detergent. Do not use petrol or other flammable liquids as they present a
fire risk and will damage the finish.
