1. Please do not use the hammer mode of the machine.
2.Before re-drilling, we must make sure that the drill bit is properly installed on the machine, firmly and without any vibration.
3.The drill bit should be clean and free from any obstructions.
4.When you are drilling, only light pressure is needed (in the horizontal direction. The pressure of the weight of the machine will be sufficient in the vertical direction.)
All the data is measured manually, so there will be a certain deviation. Please understand.
