1. The infrared level should be used in the correct way to avoid strong vibration or drop, which will affect or damage the precision of the level.
2. When using and storing the spirit level, avoid immersion in water or place it in rainy and humid areas for a long time.
3. The laser output window of the laser level should be kept clean. Regularly wipe it with a clean soft cloth or a cotton swab dipped in alcohol. If it is not cleaned for a long time, the laser line will be darker or brighter.
4. When using the infrared level, pay attention to avoid people within the measurement range, and do not look directly at the emitted laser.
5. If the laser level is not used for a long time, it must be calibrated before use.
6. If the spirit level is damaged, please do not disassemble or repair it by yourself to avoid more serious damage. You should ask someone to repair it or contact the manufacturer's after-sales maintenance service.
7. An infrared level that conforms to the safety level of laser radiation should be used.
