1 Operator s Manual 6 Litre Oil-Less Air Compressor WARNING! Before using this appliance, read the Operator s manual and follow all its safety rules and instructions.

2 SPECIFICATION HWKAC1 1.1 kw / 1.5 HP 230 Hz 2 P 2850 rpm 5.7 cfm 115 psi / 0.8 MPa 6 L 485mm x 265mm x550mm 16 kg ITEM 2

3 MAIN COMPONENTS 1. On/Off Switch 2. Outlet Valve 3. Regulating Valve 4. Pressure Gauge 5. Drain Cock 6. Air Tank 7. Release Valve 8. Fan Cover

4 PREPARATION 1. Check all nuts and bolts are tight before starting. 2. Before Starting the Compressor; Ensure power switch is set to OFF. 3. Plug compressor in to socket. 4. Pull up the red power switch and tun for 30 minutes to break in pump parts. 5. Bleed air by turning the regulator know fully counter clockwise. 6. Attach tool and hose to the compressor using the quick release couplings. 4

5 OPERATION & 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 - do not alter it carelessly. 2. As soon as the motor is switched off the compressed air in the discharge pipe should be released through the release valve under the switch. This is a necessary condition before restarting or the motor will be damaged. 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. 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. 5

6 WARNINGS 1. Never unscrew any connecting parts while the tank is pressured. 2. Never disassemble any electrical parts before disconnecting the plug. 3. Never adjust the safety valve carelessly. 4. Never use the compressor when the voltage is too low or too high. 5. Never use an electric wire more than 5m long with less than a 1.5mm² section rated to 16A. 6. Never disconnect the plug to stop the compressor. Set the switch knob to off and follow instructions on page If the release valve doesn t work when the motor is stopped find the cause immediately so as not to damage motor. 8. After motor has been switched off and compressed air has been safely discharged, Switch off and disconnect the plug to cut off the power supply. Never leave compressor plugged in when not in use. 9. Never operate near flammable gas or vapour. 6

7 MAINTENANCE 1. Do not carry out any maintenance whilst compressor is on - ensure motor is not running, compressed air and condensation is bled and compressor is disconnected from any power supply (see pages 5 + 6). 2. Pull ring on safety valve an allow it to snap back in to normal position. Safety valve must be replaced if it cannot be actuated or it leaks air after ring is released. 3. Turn compressor off and release pressure from system. Drain moisture from tank by opening drain cock located on the underside of the tank. 4. Clean dust and dirt from the motor, tank, airlines, pump and cooling fins while compressor is off. 5. Unclip the air filter cover, remove the filter and blow away any loose dirt. If damaged or badly contaminated, it must be replaced. 6. Clean the fins of the compressor cylinder and the cylinder head to receiver pipe. 7. Locate the compressor as far away from spraying area as possible, Extending the hose will help prevent overspray which may clog the filter. Take care not to over extend. 8. Do not lubricate. Oil-Less compressors require no lubrication. 7

8 TROUBLESHOOTING Symptom Possible Cause (s) Corrective Action Compressor will not run 1. No electrical power 2. Blown fuse 3. Breaker open 4. Thermal overload open 5. Pressure switch bad 1. Plugged in? Check fuse/breaker or motor overload 2. Replace blown fuse 3. Reset, determine cause of problem 4. Motor will restart when cool 5. Replace Symptom Possible Cause (s) Corrective Action Motor hums but cannot run or runs slowly Fuses blow/circuit breaker trips repeatedly CAUTION! Never use an extension cord with this product Thermal overload protector cuts out repeatedly Knocks, rattles, excessive vibration Tank pressure drops when compressor shuts off Compressor runs continuously and air output is lower than normal/low discharge pressure Excessive moisture in discharge air Compressor runs continuously and safety valve opens as pressure rises Excessive starting and stopping (auto start) Air leaking from unloader on pressure switch 8 1. Defective check valve or unloaded 2. Poor contacts, line voltage low 3. Shorted or open motor winding 1. Incorrect size fuse, circuit overloaded 2. Defective check valve or unloaded 1. Low voltage 2. Clogged air filter 3. Lack of proper ventilation/room temperature too high 4. Check valve malfunction 5. Compressor valves failed 1. Loose bolts, tank not level 2. Defective bearing on eccentric or motor shaft 3. Cylinder or piston ring is worn or scored 1. Loose drain cock 2. Check valve leaking 3. Loose connections at pressure switch or regulator 1. Excessive air usage, compressor too small 2. Clogged intake filter 3. Air leaks in piping (on machine or in outside system) 4. Broken inlet valves 5. Piston ring worn 1. Excessive water in tank 2. High humidity 1. Defective pressure switch 2. Defective safety valve Excessive condensation in tank Check valve stuck in an open position 1. Replace or repair 2. Check connections, eliminate extension cork if used, check circuit with voltmeter 3. Replace motor DANGER! Do not disassemble check valve with air in tank; bleed tank 1.Check for proper fuse, use time-delay fuse. Disconnect other electrical appliances from circuit or operate compressor on its own branch circuit 2.Replace or repair DANGER! Do not disassemble check valve with air in tank; bleed tank 1. Eliminate extension cord, check with voltmeter 2. Clean filter (see Maintenance section) 3. Move compressor to well ventilated area 4. Replace 5. Replace valve assembly DANGER! Do not disassemble check valve with air in tank; bleed tank 1. Tighten bolts, shim tank to level position 2. Replace 3. Replace or repair as necessary 1. Tighten 2. Disassemble check valve assembly, clean or replace 3. Check all connections with soap and water solution and tighten 1. Decrease usage or purchase unit with higher air delivery (SCFM) 2. Clean or replace 3. Replace leaking components or tighten as necessary 4. Replace compressor valves 5. Replace piston and cylinder 1. Drain tank 2. Move to area of less humidity; use air line filter NOTE: Water condensation is not caused by compressor malfunction 1. Replace switch 2. Replace safety valve with genuine replacement part Drain more often Remove and replace check valve DANGER! Do not disassemble check valve with air in tank; bleed tank

11 SAFETY 1. Prior to use, 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. 2. When operating the air compressor, always use eye protection such as goggles, making sure that other people in the work area are also using eye protection. 3. Eye protectors must provide protection from flying particles both from the front and from the side. 4. Hearing protection should be worn when operating this compressor, use ear plugs or ear defenders. 5. Never place your hand near any moving parts on the air compressor or operate with the covers removed. 6. Never operate the air compressor in wet or damp locations. 7. Loose clothing or jewellery may be caught in moving parts. Always tie long hair back, and wear suitable clothing. 8. Clear the work area of all unnecessary tools, debris and furniture. 9. During operation, the motor, connections, compressor body, cylinder head and tubes may get hot, do not touch. 10. Do not direct the air stream at people or animals. Compressed air can cause soft tissue damage and propel dirt and other particles at high speed. 11. This compressor should not be used to supply breathing quality air. Never use it as breathing apparatus. 12. 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. 13. 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. 14. If the air compressor is damaged in any way, have it repaired by a qualified engineer. 15. Using extension leads can cause your compressor motor to burn out. Only use extension hoses. 11
