Need help?Do you have a question about the ARB CKMP12V2 and is the answer not in the manual?
The ARB CKMP12V2 Portable Compressor Kit is a world-class recreational product designed and built to commercial and industrial standards, boasting a range of features for reliable and efficient operation.
The primary function of the ARB CKMP12V2 is to provide portable compressed air for various applications, including tire inflation and operating air tools. It is designed for ease of use and durability, making it suitable for off-road enthusiasts and anyone needing a robust portable air source. The compressor is housed in a waterproof and impact-resistant polymer case, ensuring its protection in harsh environments. It features a fully assembled and performance-tested air compressor, ready for immediate use.
The compressor is equipped with a 100% ball bearing equipped motor, featuring a unique linear brush pre-load system for extended life, low heat, and quiet operation. It includes a pressure switch and a 40 amp automotive relay equipped electrical system to prevent run-on when not filling or damage from a kinked air line. An illuminated isolating switch is present for easy night use, protecting the user from hazardous sparking when connecting alligator clips to battery terminals. Heavy-duty Maxi-Fuse equipped power leads ensure professional in-line circuit protection. The hard-anodized cylinder bore and PTFE (Teflon) impregnated carbon fiber piston seal reduce friction and maximize trouble-free life. The compressor piston is equipped with a German-made high shock-rated cylindrical roller bearing. High density and high flow washable sintered bronze air filter element are included. An over-pressure safety valve is equipped as a back-up protection from either pressure switch failure, thermal over pressure generated in a hot vehicle, or an accidental connection to an external high pressure source.
The compressor is designed for straightforward connection and operation. To connect, position the compressor on a sturdy flat surface and open the box. Ensure the switch is in the 'OFF' position. Uncoil the power lead and connect the positive (+) alligator clamp (RED handle) directly to the positive (+) terminal of the vehicle's 12-volt battery. Then, connect the negative (-) alligator clamp (BLACK handle) directly to the negative (-) terminal of the vehicle's 12-volt battery. The switch should illuminate, indicating power connection, but the compressor will not start until the switch rocker is pressed on the bottom.
Attach the air hose to the compressor by inserting the male end into the hose coupling and pressing inward until it clicks forward. The sleeve does not need to be pulled back. Attach the tire filler or other compatible device to the opposite end of the hose. To start the compressor, press the bottom of the rocker switch. Once compressed air has expelled through the attached device, the compressor will automatically start running and continue until air use stops and the pressure reaches the pre-set pressure switch cut-out level.
For tire filling, it is crucial to connect the compressor to the vehicle's battery or another 12V DC power supply. If the vehicle is in a well-ventilated area, leaving it running at idle will provide maximum compressor performance and avoid depleting the vehicle's battery. The ARB's tire filler attachment is equipped with a stop valve, ensuring air will not pass through until connected to a tire valve. The compressor will automatically start once air passes through the filler. To stop filling, remove the filler from the valve, push the silver filler body toward the tire, then pull back on the black filler collar. This will release the filler's grip on the valve. Periodically disconnect the filler and check the tire pressure with an automotive tire pressure gauge. It is important not to fill tires over the manufacturer's specified maximum pressure rating. To protect the tire valve, always refit the tire valve cap once the tires are inflated to the desired pressure.
The compressor includes built-in protection devices: a thermal cutout switch and an over-pressure safety valve. The thermal cutout switch turns off the compressor if the internal temperature approaches a dangerous level due to heat generated during compression or by the motor. It automatically resets and turns the compressor back on once it has cooled to a safe temperature. The over-pressure safety valve is factory-set to bleed off excessive pressure buildup to atmosphere, preventing personal danger or damage to components, especially if the pressure switch fails or if the compressor is exposed to high ambient temperatures. Users are advised never to disable or modify these built-in protection devices.
The manual outlines key maintenance procedures to ensure the longevity and optimal performance of the compressor.
The CKMP12V2 comes factory-fitted with a high density, high flow, sintered bronze air filter to protect the compressor components from dirt and fine dust particles. The filter element is removable and cleanable for continuous service. To service the air filter:
The compressor has an inline positive (+) power lead with an electrical fuse. If the fuse needs replacement, open the black rubber fuse housing cover and pull straight outward on the fuse until it slides free of the fuse block. The fuse should only be replaced with a fuse of the same type (maxi blade type) and of the same amp rating or less.
The CKMP12V2 is equipped with a safety valve to relieve any excessive pressure. If a fault in the pressure switch circuit occurs, or if pressure is generated from prolonged exposure to direct sunlight or an accidental connection to a higher source of pressure, the safety valve will activate. If it becomes necessary to service this valve to change the relief pressure (e.g., use an alternate spring) or clean the valve seat, it can be easily disassembled as follows:
