A hand drill is a commonly used drilling power tool powered by an AC power source or a DC battery. If you don’t use the hand drill correctly, you may hurt others and yourself. What should you pay attention to when using the hand drill correctly?
1.Ensure the safety of the circuit: before and during use, ensure that the circuit is normal, the wires connected to the power supply are not damaged, and the skin is leaking. If there are exposed wires, wrap them with insulating tape before use.
2.Ensure the safety of the switch device: turn off the switch when the hand drill is not in use, to prevent the next time using the power drill to suddenly turn and hurt people.
3.Check before use: Before use, the hand drill should be idling for 0.5 to 1 second after turning on the switch to check whether the transmission part is flexible, whether there is abnormal noise, whether the screws are loose, and whether the commutator spark is normal.
4.The control method should be correct: when drilling holes with a hand electric drill, you should hold both hands tightly, and try not to operate with one hand.
5.The drill bit is selected correctly: the drill bit of the hand electric drill cannot be used with a notched drill bit. When drilling, the downward pressure should not be too strong to prevent the drill bit from being interrupted.
6.The drilling force should be moderate: when the electric drill is drilling the object, the drilling force should not be too strong, and the force should not be used to prevent the drill bit or the wire tapping from flying out and hurting people.
7.Troubleshoot in time: If the hand electric drill finds that there is a large spark on the commutator and the electric drill is overheated, it must be stopped and checked, such as removing dirt, replacing worn brushes, adjusting the spring pressure of the brush holder, etc. use.
