1. Correct maintenance and upkeep of nitrogen-filled trolleys is the first prerequisite for proper and reliable operation. One of the main points is the cleaning of the car body. When cleaning, you should use the correct reagents to decontaminate, and use non-lint cleaning paper towels, non-lint cleaning cloths, cleaning woolen fabrics, etc. for scrubbing.
2. It is forbidden to use any abrasive cleaners. At the same time, care must be taken that the cleaners do not leak into the N2 nitrogen-filled booster device or individual components, otherwise the service life of the nitrogen-filled trolley will be affected.
3. The hose should be checked regularly for any distortion and wear. Damaged or twisted hoses should be replaced immediately. Always monitor the liquid level displayed on the level gauge before and after nitrogen filling.
4. One last point that needs to be stated is that it is forbidden to perform any maintenance work on the nitrogen-filled trolley when it has not been turned off and cut off.
