SAFETY PRECAUTIONS WARNING! As with all machinery, there are certain hazards involved with their operation and use. Exercising respect and caution will considerably lessen the risk of personal injury. However, if normal safety precautions are overlooked, or ignored, personal injury to the operator, or damage to property may result.
SAFETY PRECAUTIONS TRAINING: Prior to use all operators should become familiar with the instructions in this booklet. In particular, become familiar with the ON/OFF control for emergency stopping. ALWAYS WEAR EYE PROTECTION: When operating the air compressor, always wear eye protection, and make sure that other people in the work area are also wearing eye protection. Eye protectors must provide protection from flying particles both from the front and from the side.
SAFETY PRECAUTIONS STORE THE AIR COMPRESSOR PROPERLY: When not in use the air compressor should be stored in a secure, dry place out of the reach of children. Always lock up the storage area. PROTECT YOUR HEARING: Ear protection should be worn when operating this compressor. MAINTAIN THE AIR COMPRESSOR WITH CARE: If the air compressor is damaged in any way, have it repaired by a qualified service engineer.
SAFETY PRECAUTIONS KEEP ALL SCREWS AND COVERS TIGHTLY IN PLACE: Check the screws and covers periodically. ADEQUATE VENTILATION: The compressor should only be used in areas with adequate ventilation and should not be exposed to heat, or used near inflammable substances. NEVER USE AN AIR COMPRESSOR WHICH APPEARS DEFECTIVE OR IS OPERATING ABNORMALLY: If the compressor operates unusually or makes strange noises, switch off immediately and purge the air tank. Arrange repair with an authorised service centre.
SAFETY PRECAUTIONS NEVER STOP THE COMPRESSOR BY REMOVING THE PLUG OR SWITCHING OFF AT THE MAINS SUPPLY: Always use the On/Off switch on the compressor. NEVER OPERATE WITHOUT ALL GUARDS IN PLACE: Never operate without all guards or safety features in place and in proper working order. NEVER OPERATE IN THE PRESENCE OF FLAMMABLE LIQUIDS OR GASES: The air compressor produces sparks during operation.
WARNING SYMBOLS READ THIS INSTRUCTION BOOKLET CAREFULLY BEFORE POSITIONING, OPERATING OR ADJUSTING THE COMPRESSOR. Risk of electric shock. The compressor must be disconnected from the mains supply before removing any covers. Do not use in a damp environment. Risk of accidental start-up. The compressor could start automatically in the event of a power cut and subsequent reset. Do not carry the compressor while it is connected to the power source, or when the tank is filled with compressed air.
ELECTRICAL CONNECTIONS Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.

ASSEMBLY WARNING! Before assembling and using the air compressor, make sure that you have read and understood all of the safety instructions. Installation Take care when lifting the compressor from the packaging. CAUTION! Do not lift the compressor by the pressure regulator and cut-out. Get assistance if necessary. This unit weighs 21 kg. After removing the compressor from its packaging, check the integrity of the unit, making sure it has not been damaged in transit.
ASSEMBLY Locating the air compressor This compressor should be positioned on a stable, flat surface (or one with a maximum inclination of 15O). See figure 3, and ensure that it is copletely stable. Do not cover or box in the compressor. Always position it with good all round ventilation.
PREPARING FOR USE Before connecting your compressor to the mains supply, check the following:• The mains voltage is 230V. • The ON/OFF switch is in the OFF (lower) position. • The pressure regulator should be set at its lowest setting, i.e. turned fully anticlockwise. • If the machine has not been used for 24 hours or so, open the drain valve to drain any condensate which may have accumulated. When clear, close the valve, finger tight.
OPERATING INSTRUCTIONS Switching the air compressor ON The compressor will make a continuous loud noise when the tank is charging this is normal. 1 Lift the red On/Off switch located on top of the pressure regulator to switch the compressor ON. • The compressor will then charge the main tank to 8 bar (116 psi). When this pressure is reached, the compressor will switch itself off. • The compressor will restart automatically whenever the pressure in the main tank falls below around 6 bar (87 psi).
OPERATING INSTRUCTIONS 5 The illustration below shows the pressure regulator locked at 6 bar. • Never set the pressure higher than the rated pressure of the attachments being used, as there is a risk of bursting and resultant injury. To increase the output pressure from this preset value you will need to intentionally loosen the locking ring. • Only alter this setting if you are using an air tool with a higher pressure requirement. 6 Open the outlet tap.
OPERATING INSTRUCTIONS Switching the air compressor OFF To switch the air compressor off, 1. Close the outlet tap and press down the on/off switch (red button) located on top of the air compressor. 2. Switch off the mains supply and remove the plug. • You should never leave the compressor air reservoir unattended while under pressure, as this may result in an accident.
OPERATING INSTRUCTIONS Draining the reservoir CAUTION! It is important to drain the reservoir before storage. 1 Switch the air compressor off, by pressing down the red On/Off button, and remove the plug from the mains supply. • Place a suitable container beneath the compressor to catch any condensation. 2 Carefully undo the drain valve anti-clockwise until you hear a hissing noise, this is the reservoir depressurising.
ROUTINE MAINTENANCE IMPORTANT: Before carrying out any maintenance, always disconnect the compressor from the mains supply, drain the air receiver and, if necessary, allow the machine to cool down before starting work. Daily Drain the tank After use, always open the drain valve to ensure that any liquid that may have condensed, is drained off. See page 18. Monthly The air intake filter should be inspected on a MONTHLY basis, and more often in dusty conditions, To clean the air intake filter, 1.
ROUTINE MAINTENANCE Every six months • Make sure that all bolts are securely tightened. • Clean all the external parts of the compressor.
