Frequently Asked Questions - 40-9444 Cocraft

How do I use the compressor for the first time?

Before first use, check oil level if applicable (this model is oil-free, so no oil needed). Connect the hose and tool, plug into mains, turn on the switch, and allow pressure to build. Adjust regulator as needed. Always read the user manual.

Does this compressor require oil?

No, the Cocraft 40-9444 is an oil-free compressor, which means it does not require oil lubrication. It is maintenance-free regarding oil changes.

How do I drain the water from the tank?

Regularly drain moisture by opening the drain valve at the bottom of the tank. Aim the valve away from you and open slowly. Do this after each use or daily to prevent corrosion.

What is the maximum pressure I can set?

The maximum pressure is 8 bar (116 psi). Do not exceed this pressure. Adjust the regulator to match tool requirements. The safety valve will release if overpressure occurs.

Why is the compressor not building pressure?

Check for leaks in hoses or connections, ensure the drain valve is closed, and verify that the pressure switch is functioning. If the motor runs but no pressure builds, the intake filter may be clogged or the check valve faulty.

Can I paint with this compressor?

Yes, with a suitable spray gun and proper air preparation (water trap, regulator). The compressor has sufficient flow for small to medium painting jobs. Ensure the air is dry and clean.

What safety precautions should I take?

Always wear safety glasses and hearing protection. Do not point the air stream at people or animals. Use a pressure regulator to avoid over-inflating. Disconnect power when not in use. Read the safety section in the manual.

How often should I replace the air filter?

The air filter should be checked monthly and replaced if dirty, typically every 3-6 months depending on usage. A clogged filter reduces performance and can cause the motor to overheat.

What accessories are compatible?

Most pneumatic tools with a standard 1/4-inch quick connector are compatible, such as impact wrenches, nail guns, blow guns, and tire inflator attachments. Ensure they match the pressure and flow requirements.

Where can I find spare parts or service?

Spare parts like filters, pressure switches, and valves are available from Cocraft dealers or online. For repairs, contact an authorized service center. The model number 40-9444 is needed for identification.

• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
  • Children shall not play with the appliance.
• Cleaning and user maintenance shall not be made by children without supervision.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• Always wear eye protection. Wear a pair of safety glasses or goggles. Never point the air stream towards any part of your body or towards another person.
• Guard against electric shock. Do not use the air compressor in damp or wet locations or in the vicinity of water.
• Unplug the air compressor when it is not in use. Turn off and unplug the air compressor from the wall socket before carrying out any maintenance.
• Avoid unintentional starting. Do not move the air compressor when it is connected to the power supply.
• Store the air compressor in a safe place. When the air compressor is not in use, it should be kept in a dry place, away from children.
• Keep the work area clean. Cluttered surfaces and benches invite accidents.
• Keep the air compressor out of children's reach. Keep children and visitors at a safe distance from electrical machinery/tools and electric cables in the workplace.
• Do not abuse the mains lead. Do not carry the air compressor by its mains lead. Do not yank the mains lead to unplug the air compressor, hold the plug when pulling it out of the socket. Make sure that the mains lead does not come into contact with heat, oil, or sharp edges.

• Use the correct size and type of extension lead. If you use extension leads outdoors, only use those designed for outdoor use. Only use extension leads with thick enough diameter core wires and roll out the whole lead.

• Use common sense and be careful. Think before carrying out any task, so that it is carried out safely. Never operate the air compressor when you are tired, under the influence of medicine etc.

• Use the air compressor for the purpose it was designed for. Follow all the instructions in this instruction manual. Do not allow children or people unfamiliar with the air compressor to operate it.
• Regularly check that all screws are adequately tightened.
• Make sure that the mains supply voltage is compatible with the rated voltage of the air compressor. The motor can overheat if the supply voltage is too high.
• Do not use the air compressor if it is damaged. If the air compressor emits unusual noises or heavy vibrations or shows any other signs of damage it should be switched off immediately. Contact customer services to find out what the cause of the problem is.
• Use only recommended replacement parts. The use of non-recommended spares could damage the air compressor.
• The air compressor must not be modified. Contact customer services before carrying out any repairs to the air compressor. Modifications carried out on the user's own authority can lead to personal injury or damage to the air compressor.
• Do not touch any hot surfaces on the air compressor. Burn hazard.

Product description

Mini, oil-free piston air compressor with air regulator, suitable for supplying an airbrush or other small spray gun with air.

Operating instructions

1. Connect an air tool (brush/sprayer) to the air outlet connector (6) on the pressure regulator (7).

2. Mix the paint to a suitable viscosity.

3. Plug the mains lead of the air compressor into a wall socket and set the switch (1) to position 1 to switch the air compressor on. The compressor will start to compress air straight away and continue to build up the pressure until it reaches 4 bar. The compressor will start compressing the air again if the pressure drops to 3 bar.

4. Drain any water out of the water trap (8) by pushing up the water release valve at the bottom of the water trap.

5. Always practice spray on a test object before spraying the subject to be painted.

- Practice on a similar surface first, set the air pressure using the pressure regulator and plan your technique before beginning work on the subject to be painted.

- To set the air pressure: lift the upper knob (4) on the pressure regulator (7), turn it clockwise to increase, or anticlockwise to decrease the output pressure. Push the upper knob down to lock the setting.
