 Use of the fixture 
 Chucking and repeatedly adjust the fixtures before the top wire by hand, so that the upper pressure just compression of the rail surface. 
 The upper and lower position adjustment: release the card side of the two fastening screws, rotate the adjustment screw position after a good tune, Tighten the fastening screws. 
 Check the power supply is good contact, virtual access is strictly prohibited, to avoid burning the motor. 
 Aircraft equipped with water injection watering can, and must be filled with coolant in the drilling process in order to extend the bit life. 
 Drilling process, the feed operation to force fit, Do not too fast, too fast, found rotation exception, should reduce the force, to prevent overload.
