Instructions for use:
1. Before the vibrator moves, check whether the power phase connection is correct. After the power is turned on, if the vibrating bar does not vibrate, the vibrating rod end can generally be smashed to the ground, and the vibrating operation can be performed after the vibration emits a balanced and powerful squeaking sound.
2. When the vibrator is working, the vibrating bar should be inserted into the concrete vertically or obliquely. After vibrating for a certain period of time, the vibrating bar should be twitched up and down during vibration.
3. After the vibrator has been working for half an hour, it should be stopped for a period of time to prevent mechanical heating and even damage the machine.
4. In order to protect the flexible shaft and hose, the bending radius should be no less than 500mm.
