Frequently Asked Questions - L350 Cocraft
How do I properly start the compressor?
Before starting, ensure the pressure switch is in the OFF position. Plug the compressor into a 230 V earthed socket, then turn the pressure switch to ON. Let the tank fill until the motor cuts off automatically, which indicates the cut-out pressure has been reached. The compressor is then ready for use.
How do I adjust the pressure regulator?
To adjust the working pressure, loosen the regulator knob by turning it counterclockwise. Then turn the knob clockwise to increase or counterclockwise to decrease the output pressure. Tighten the knob to lock the setting. Always check the gauge to match the tool's rating.
How often should I drain the tank?
Drain the condensation from the tank after every use or at least once a week. Open the drain valve underneath the tank when the pressure is below 2 bar, and allow moisture to escape. Regular draining prevents internal corrosion and extends the tank's lifespan.
Can I leave the compressor plugged in?
Leaving the compressor plugged in is not recommended. Although it has thermal protection, continuous standby can cause unnecessary wear and pose a risk during power surges. Always unplug the compressor when it is not in use, especially during cleaning or maintenance.
What maintenance is required for the air filter?
The air filter prevents dust from entering the pump. Check it every 25 operating hours. If it is dirty, clean it with compressed air or wash it in warm soapy water and let it dry completely. Replace the filter if damaged or heavily clogged. A clean air filter maintains air intake efficiency.
How do I check the safety valve?
The safety valve is a critical component that releases pressure if the pressure switch fails. To test it, run the compressor until it reaches cut-out pressure, then pull the ring on the valve. Air should escape with a hissing sound. If no air escapes, the valve is faulty and must be replaced immediately.
What should I do if the compressor overheats?
If the compressor overheats, the thermal overload protection will shut off the motor automatically. Turn the pressure switch to OFF and unplug the unit. Allow it to cool for at least 30 minutes. Check for any blockages in the ventilation openings and clean them. If it continues to overheat, contact an authorized service center.
Is this compressor oil-free?
Yes, the Cocraft L350 is an oil-free compressor. The pump is pre-lubricated during manufacturing and requires no additional oil. This makes maintenance simpler and prevents oil mist from contaminating the air output, ideal for inflating small items and painting.
Which accessories are compatible with the L350?
The compressor comes with a universal quick coupling suitable for most standard pneumatic tools and inflation needles. You can use it with tire inflators, blow guns, paint sprayers, and air brushes that have a lower working pressure (up to 8 bar). Always verify the tool's air consumption matches the compressor's free air delivery.
How do I store the compressor?
Store the compressor in a dry, frost-protected area. Before storage, drain the tank completely, wrap the power cord around the holder, and cover the unit to prevent dust buildup. Ensure the pressure switch is OFF and the tank pressure is zero. This prevents corrosion and keeps the compressor ready for the next use.
