Solutions for a spray gun failing to spray paint: 1. If the spray gun is not spraying paint, it may be due to a clogged paint tube. Clean the paint tube thoroughly; 2. If the paint tube is not clogged, check the paint supply pump to see if the suction cup is blocked. If it is, clean it properly; 3. Check whether the pump is functioning correctly to draw and pump paint. If there is an issue with the pump, improper paint suction can also cause the spray gun to fail to spray paint. Cleaning the pump and suction cup should resolve the issue. Precautions before using a paint spray gun: 1. Clean the nozzle. New paint spray guns often contain a lot of anti-corrosion oil, which must be cleaned before use. Otherwise, it can severely affect performance or even render the gun unusable. Also, remove grease and metal shavings from the nozzle threads and other threaded parts; 2. Clean the interior of the paint spray gun. Cleaning the interior requires the use of a paint cup.

What Causes Hybrid System Malfunctions?

Hybrid system malfunction issues occur when the vehicle fails to start (system ready light not illuminated), with the dashboard displaying "Hybrid System Malfunction". It is recommended to wait for 10 minutes. Refrigeration unit pipeline leakage: For units that use refrigerant, this issue is relatively common. Since Freon circulates in a nearly sealed pipeline, there should be no natural loss. If leakage occurs during Freon refilling, methods such as pressure testing should be employed for detection or immediate repair. Refrigeration unit compressor failure: Overheating of the refrigeration unit compressor can cause the protector to fail. If the unit itself is functioning properly, the compressor may already be damaged. The causes of refrigeration unit pipeline blockage include incomplete vacuum extraction or moisture-induced ice blockage.

The functions of tire pressure monitoring are: 1. It alerts promptly in case of rapid or slow air leakage when a tire is punctured by a nail; 2. It warns to prevent blowouts when tire loosening causes uneven friction, leading to high tire temperatures reaching 70 degrees Celsius; 3. It alerts when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts.
