The electric hand drill is a convenient and easy-to-carry small drilling tool, and consists of a small motor, a control switch, a drill chuck, and a drill bit. In order to make good use of this thing, it is not necessary to understand its operating standards, but also to understand its use, pay attention to matters, and negligent operations constitute a loss.
1. The shell of the electric drill is grounded or connected to the neutral wire for maintenance.
2. The wire of the electric drill should be well maintained to prevent the wire from being damaged or cut indiscriminately. It is not allowed to drag the wire into oil or water, which will corrode the wire.
3. Wear rubber gloves and rubber shoes when using it; when working in a humid local area, stand on rubber pads or monotonous wooden boards to prevent electric shock.
4. When electric drill leakage, tremor, high heat or abnormal noise are found during operation, you should continue to work and find an electrician to check and repair.
5. When the electric drill does not roll continuously, the drill bit cannot be unloaded or changed. The power supply should be blocked when resting or leaving the work place.
6. Can not be used to drill concrete and brick walls. Otherwise, it is very simple to cause the motor to be overloaded and burn the motor. The key lies in the lack of impact organization in the motor and low bearing capacity.
