Warning labels explained On the tank of your air compressor you will notice various warnings about the operation of the compressor.

Introduction Your new GMC power tool will more than satisfy your expectations. It has been manufactured under stringent GMC Quality Standards to meet superior performance criteria. You will find your new tool easy and safe to operate, and, with proper care, it will give you many years of dependable service.
General safety instructions To use this tool properly, you must observe the safety regulations, the assembly instructions and the operating instructions to be found in this Manual. All persons who use and service the machine have to be acquainted with this Manual and must be informed about its potential hazards.
• Always wear safety goggles or glasses when using the air compressor. Never point the nozzle of an accessory towards any part of your body or towards another person. • Do not attempt to adjust the pressure switch or the release valve.
Note. Never transport pressurised tanks. Prior to transporting the air compressor make sure the tank has been completely drained of air. • Protect the air hose and cordset from damage. Inspect for weak or worn spots regularly and replace if necessary.
Unpacking Due to modern mass production techniques, it is unlikely that your GMC Power Tool is faulty or that a part is missing. If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified. Failure to do so could result in serious personal injury.
WARNING. The air compressor must be filled with oil before first use. To prevent possible spillage of oil during transport, the compressor oil is supplied in a separate container. It must be added to the compressor before turning the compressor on.
4. To stop the compressor, lift the On/Off lever (3) to the vertical position. Operation 1. The pressure in the tank is controlled by the action of the pressure switch located under the pressure switch cover (2). When the set maximum pressure is reached the pressure switch activates and the motor is switched off.
Troubleshooting Suggested Remedy Check the power supply. Do not use an extension cord with an air compressor. Make sure that the compressor is plugged directly into a 240V household power point and not an extension cord or power board. Use authorised service centre to repair or replace the switch...
