How To Use Concrete Pavement Coring Machine Correctly

How to use concrete pavement coring machine correctly：

1. When the concrete core drilling machine is drilling, it shall ensure that the feed speed is uniform, about 3 ~ 5cm / min. if the drill bit is stuck, the feed speed can be reduced appropriately. If necessary, the drill bit can be lifted for a section, and then drilled slowly. Hard drilling is prohibited to avoid damaging the drill bit and machine.

2. Sufficient water cooling must be maintained throughout the drilling process.

3. Overload is not allowed during drilling. When the motor temperature exceeds 70 ℃ (feel hot), the loading force shall be reduced and a new drill bit shall be replaced.

4. At the end of drilling, the machine can be stopped only when the drill bit is separated from the workpiece.
