GENERAL SAFETY WARNINGS

WARNING: WHEN USING ELECTRICAL TOOLS, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE  THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL INJURY
WARNING: READ ALL THESE INSTRUCTIONS BEFORE  ATTEMPTING TO OPERATE THIS PRODUCT AND KEEP THESE INSTRUCTIONS IN A SAFE PLACE.

WORK AREA

1. Keep the work area clean and well-lit. Floors should always be kept clear.
   Cluttered or dark areas invite accidents.

2. Keep children and bystanders away while operating a compressor.
   Distractions can cause loss of control.

3. The compressor should only be used in areas with adequate ventilation and should not be exposed to heat or used near flammable substances

PERSONAL SAFETY

1. ALWAYS stay alert, watch what you are doing, and use common sense when operating the compressor. DO NOT use the compressor while you are tired or under the influence of medication, drugs, or alcohol. A moment of inattention can result in personal injury.

2. ALWAYS use eye protection when operating compressed air equipment, and ensure that others in the work area are protected from flying particles from the front and from the side.

3. ALWAYS protect yourself against electric shock. NEVER operate the compressor in wet or damp locations.

4. NEVER over-reach. Keep your proper footing and balance at all times to enable better control of the compressor in unexpected situations.

5. NEVER attempt any complex repairs yourself. If you have a technical problem contact your local CLARKE dealer.

6. ALWAYS store the compressor out of reach of children.

7. ALWAYS protect your hearing. Ear protection should be worn when operating this compressor and its associated air tools.

8. NEVER direct the airstream at people or animals, as injury may result.
   Compressed air can cause soft tissue damage and propel dirt and other particles at high speed.

9. NEVER insert your fingers or other objects inside the motor housing. NEVER operate the compressor without the cover in place.

10. NEVER touch hot surfaces. During operation, the motor, connections, compressor body, cylinder head, and tubes may get hot. DO NOT touch these until the compressor has cooled down.

GENERAL MACHINE USE AND CARE

1. Prior to use, all operators should become familiar with the instructions in this booklet especially the ON/OFF switch for emergency stopping.
2. ALWAYS maintain the compressor with care and keep it clean for the best /safest performance.
3. NEVER use this compressor if any part is damaged. Has it been inspected and repaired by your CLARKE dealer?
4. NEVER attempt to modify the air compressor, tank, fittings, or attachments in any way. Doing so will invalidate the guarantee and could result in personal injury.
5. NEVER abuse the power cable. NEVER pull on the cable when removing the plug from the socket, or lift the compressor by the power cable.
6. Only use extension leads that are of an appropriate power rating and suitable for the work environment. Extension leads must have an earth connection.  Inspect the extension lead regularly and replace if damaged.
7. ONLY USE RECOMMENDED PARTS: To avoid the risk of bursting, only hoses with rated pressure of 10 bar, or more should be used. Never attempt to repair damaged hoses.
8. NEVER abuse the compressor by standing on it.

AIRLINE HOSES

1. ALWAYS ensure that equipment or power tools used in conjunction with the compressor have a safe working pressure exceeding that of the machine.
2. ALWAYS keep the air hose away from any attached air tools and ensure that the operator is not restricted by the length of the hose.
3. ALWAYS take care when a long air hose is required in the work area as it presents a trip hazard. Coil the hose away as soon as the job is finished.
4. ALWAYS avoid kinking or trapping the air hose. ALWAYS replace faulty hoses and never attempt a repair if a leak is detected.
5. NEVER abuse hoses or connectors. NEVER carry an air tool by the hose, or yank it to disconnect from the air supply. Keep hoses away from heat, oil and sharp edges. Check hoses for leaks or worn conditions before use and ensure that all connections are secure.
6. ALWAYS ensure that the air supply is turned off at the machine outlet and any air pressure vented from within the compressor and any attached equipment when disconnecting air hoses or other equipment.

• Ensure it is switched off and disconnected from the power supply.

OPERATION

If the compressor has not been used for more than 24 hours, open the drain valve on the bottom of the reservoir and drain any condensate which has been collected.  See page 12.

ATTACHING AIR TOOLS
WARNING: BEFORE CONNECTING AIR TOOLS, MAKE SURE THAT YOU READ THE INSTRUCTIONS SUPPLIED WITH THE TOOL, ALSO  ENSURE THAT THE AIR TOOL IS SUITABLE FOR USE WITH THE COMPRESSOR AND HOSE SPECIFICATIONS.

1. Attach the air hose to the ¼” BSP outlet valve.
2. Attach the tool to the end of the air hose.
3. Turn the outlet valve handle to the on position.

NOTE: The outlet valve is shown without the air hose fitted for clarity.

TURNING THE COMPRESSOR ON

1. Plug the compressor into the power supply.
2. Lift the On/Off button.
   • The compressor will operate until the reservoir is fully pressurized. It will then shut down.
   • The compressor will start up again when the pressure in the reservoir decreases.

SET THE OUTPUT PRESSURE

1. Use the pressure regulator to set the output pressure of the left-hand outlet valve.
   • Turn clockwise to increase the pressure.
   • Turn counterclockwise to decrease the pressure.

GAUGES

1. The reservoir pressure gauge shows the current pressure in the reservoir.
2. The outlet pressure gauge shows the ‘user set’ outlet pressure. This can be adjusted as shown above.

REMOVING TOOLS FROM THE AIR HOSE

WARNING: ALWAYS SET THE PRESSURE REGULATOR TO ZERO BEFORE YOU REMOVE OR REPLACE A TOOL.

1. Push down on the On/Off button to stop the compressor.
2. Turn the outlet valve handle to the off position.
3. Operate the tool to depressurize the air hose.
4. Disconnect the tool from the hose.

TURNING THE COMPRESSOR OFF

1. Follow steps 1-3 in “Removing Tools from the Air Hose” above.
2. Disconnect the compressor from the power supply.
3. Slowly open the outlet valve to depressurize the reservoir.
   • You will hear a hissing sound as the reservoir depressurizes.
   • Do not leave the compressor unattended if the reservoir is pressurized.

DRAINING THE RESERVOIR

CAUTION: YOU MUST DRAIN THE RESERVOIR AFTER EACH DAYS USE AND BEFORE YOU PUT YOUR COMPRESSOR INTO STORAGE.

1. Turn the compressor off and disconnect from the power supply.

2. Put a container below the drain valve to collect the condensate

3. Open the drain valve slowly.
   • Condensation will drain from the reservoir.

4. Close the drain valve when the reservoir has fully drained.

RESET BUTTON
This compressor has a thermal overload device. If the motor gets too hot, the thermal overload device cuts the power which prevents damage to the motor.
If the thermal overload device operates, let the motor cool down for 5 minutes and push the reset button. If you start the compressor and the overload cutout operates again, stop the compressor and disconnect from the power supply and have your compressor examined by a qualified service agent.

MAINTENANCE

CAUTION: ALWAYS DISCONNECT FROM THE POWER SUPPLY BEFORE CARRYING OUT ANY MANTENANCE
DRAINING THE RESERVOIR
After use, always open the drain valve to make sure that any condensate is drained off.

CLEANING THE AIR FILTER
The air filter should be examined occasionally in dusty conditions,

1. Unscrew the plastic shroud from the compressor to expose the working components.

2. Clean the sponge filter using a soft brush. If necessary, the filter can be carefully cleaned in warm soapy water.
   • Rinse and let the filter dry completely before refitting.

3. Refit the filter assembly before use.
   • If the filter is damaged it must be replaced.

4. Refit the plastic shroud. This should always be fitted before reconnecting and starting the compressor.

CHECKING THE NON-RETURN VALVE

If the reservoir pressure decreases for no apparent reason it is possible that the non-return valve is leaking. To check;

1. Make sure that the reservoir is not under pressure and the compressor is switched OFF.
2. Examine the non-return valve, and replace the gasket and valve if necessary.
