WARNING SYMBOLS READ THIS INSTRUCTION MANUAL CARE- FULLY BEFORE OPERATING OR ADJUSTING THE COMPRESSOR. Risk of electric shock. The compressor must be disconnected from the mains supply before maintenance or 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. This compressor contains surfaces which may reach a high temperature during operation. Never operate with the motor housing removed. Air and condensation water can burst from the compressor when the drain plug is removed. Wear a safety goggles and ear protectors when using this compressor. This compressor produces a high sound level during operation. Ear protection should be worn. PAGE 3
SAFETY PRECAUTIONS TRAINING: Prior to use, all users must become familiar with the instructions given in this manual. In particular, become familiar with the ON/OFF control for stopping the compressor in the event of an emergency. ALWAYS USE EYE PROTECTION: When operating the air compressor, always use eye protection such as goggles, and make sure that other people in the work area are also using eye protection. Eye protectors must provide protection from flying particles both from the front and from the side. PROTECT YOUR HEARING: Hearing protection should be worn when operating this compressor, use ear plugs or ear defenders. NEVER TOUCH MOVING PARTS: Never place your hand near any moving parts on the air compressor or operate with the covers removed. PROTECT YOUR SELF AGAINST ELECTRIC SHOCK: Never operate the air compressor in wet or damp locations. DRESS PROPERLY: Loose clothing or jewellery may be caught in moving parts. Always tie long hair back, and wear suitable clothing. WWW.SGS-ENGINEERING.COM PAGE 4
SAFETY PRECAUTIONS KEEP VISITORS/CHILDREN AWAY: Do not allow visitors/children to handle the air compressor or attachments and ensure that any people in the work area are suitably dressed. KEEP THE WORK AREA CLEAN: Cluttered areas mean accidents, so clear the work area of all unnecessary tools, debris and furniture. DO NOT TOUCH HOT SURFACES: During operation, the motor, connections, compressor body, cylinder head and tubes may get hot, do not touch. DO NOT DIRECT AN AIR STREAM AT THE BODY: Do not direct the air stream at people or animals, as injury may result. Compressed air can cause soft tissue damage and propel dirt and other particles at high speed. BREATHING AIR: This compressor should not be used to supply breathing quality air. Never use it as breathing apparatus. STAY ALERT: Watch what you are doing, use common sense, and do not operate the air compressor when you are tired. The air compressor should not be used if you are under the influence of alcohol, drugs or any medication that makes you drowsy. PAGE 5
SAFETY PRECAUTIONS DISCONNECT THE AIR COMPRESSOR: Always disconnect the air compressor from the mains power supply and decompress before performing maintenance, changing any parts and when not in use. MAINS POWER CABLE PRECAUTIONS: Never pull on the cable when removing the plug from the mains socket, or lift the compressor by the mains cable. AVOID UNINTENTIONAL STARTING: When connecting the air compressor to the mains supply make sure the red button on top of the air compressor is in the OFF (down) position. 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. MAINTAIN THE AIR COMPRESSOR WITH CARE: If the air compressor is damaged in any way, have it repaired by a qualified engineer. DO NOT USE EXTENSION LEADS: Using extension leads can cause your compressor motor to burn out. Only use extension hoses. WWW.SGS-ENGINEERING.COM PAGE 6
SAFETY PRECAUTIONS DISPOSAL INFORMATION: The air compressor should be disposed of in a safe an environmentally friendly manner. Contact your local Council for disposal assistance. DO NOT WELD TO THE PRESSURE VESSEL: Do not weld or modify the pressure vessel in any manner. PAGE 7
ASSEMBLY Check all nuts and bolts. Make sure all loosened parts are tightened before starting. Remove the white travel plug and attach the air filter, tightening hand tight only. BEFORE USE 1. Ensure the power is OFF by pushing in the power switch. WWW.SGS-ENGINEERING.COM PAGE 8
PREPARATION FOR STARTING 2. Push in switch to OFF position, and plug in power cord at the wall. 3. Pull up the red power switch and run compressor unit for 30 minutes to break in the pump parts. PAGE 9
PREPARATION FOR STARTING 4. Turn regulator knob fully counterclockwise to cause air to bleed off. 5. Attach the hose and tool to the compressor using the Euro type quick release couplings on the compressor. WWW.SGS-ENGINEERING.COM PAGE 10
OPERATION AND ADJUSTMENT 1. The compressor is controlled by a pressure switch. It can be stopped automatically as the pressure increases to the maximum and restarted as pressure decreases to the minimum. The rated pressure has been adjusted during the manufacturing process - don t alter it carelessly. 2. As soon as the motor is switched off the compressed air in the discharge pipe should be released through the drain-cock. This is a necessary condition before restarting or the motor will be damaged. PAGE 11
OPERATION AND ADJUSTMENT 3. The output pressure of compressed air can be regulated by using the regulating valve. turn the regulation valve knob clockwise to increase the pressure. 4. When the compressor needs to be stopped, set the power switch to the OFF position. WWW.SGS-ENGINEERING.COM PAGE 12
OPERATION AND ADJUSTMENT 5. If the compressor should overheat, the Thermal Overload will intervene and shut down the compressor. Should this happen, switch OFF the machine by pushing the STOP/START switch downwards, and wait for at least 5 minutes before pressing the red RESET button underneath the air filter and try to start the compressor again. PAGE 13
MAINTENANCE 1. Disconnect power source then release all pressure from the system before attempting to install, service, relocate or perform any maintenance. 2. Check compressor often for any visible problems and follow maintenance procedures each time compressor is used. 3. Pull ring on safety valve and allow it to snap back to normal position. Safety valve must be replaced if it cannot be actuated or it leaks air after ring is released. 4. Turn compressor off and release pressure from system. Drain moisture from tank by opening drain cock underneath tank. 5. Clean dust and dirt from motor, tank, and airlines and pump cooling fins while compressor is still OFF. 6. IMPORTANT: Locate unit as far from spraying area, as hose will allow preventing overspray from clogging filter. 7. Unclip the air filter cover, remove the filter and blow away any loose dirt. If damaged or badly contaminated, it must be replaced. 8. Clean the fins of the compressor cylinder and the cylinder head to receiver pipe. A clean compressor will work more efficiently. 9. LUBRICATION This is an oilless type compressor requiring no lubrication. WWW.SGS-ENGINEERING.COM PAGE 14
MAINTENANCE CLEAN THE AIR FILTERS (MONTHLY) The air filters must be examined monthly, more often in dusty conditions: 1. Remove the filter covers from the compressor. 2. Remove the filter covers from the filters. 3. Remove the filters from the filter covers. 4. Clean the sponge and both the filters cover using a soft brush.if necessary, the filters can be carefully cleaned in warm soapy water. Rinse and let the filters dry completely before refitting. 5. Make sure that the filters and filter covers are replaced into position. If the filters are damaged, you must replace them. PAGE 15
