A hand-held electric drill is a widely used tool in our lives. Before it can be used, it must be installed with a drill. So, how to replace the drill of a hand electric drill?
A specific operation looks like this:
First, turn off the power supply, unplug the power cord from the socket, and place the hand drill steadily upwards. When disassembling the drill, insert the key into the drill card, align the gears on the key with the gears on the drill card, and then turn the key.
Clockwise to tighten, counterclockwise to loosen. When replacing the drill, wear thicker gloves, then squeeze the neck of the rubber drill and turn it counterclockwise to complete the disassembly of the drill. Then turn it clockwise to replace the drill with a new one. The operation is relatively simple.
Being an electric tool, a hand-held electric drill also requires safety precautions when using it. For our safety, we must test these elements before using them:
First check if the power cord is not damaged, wrap the damaged part with electrical tape, and then put the power cord in a place where there is no water and cannot be stepped on. Check the drill bit for cracks or gaps, and replace it in time if any problems occur. Before use, make sure the switch of the hand drill is turned off to avoid the hand drill turning violently when the plug is inserted into the socket.
During use, the work must be correct:
After connecting, let it idle for half a minute to one minute to check if the transmitting part is flexible, if there is any abnormal noise, if the screws are loose, and if the commutator spark is normal. Use as usual.
When drilling holes, hold the power drill firmly with both hands and do not work with one hand. To prevent the drill from breaking, do not press the drill too hard. Actions such as cleaning up debris and changing the cutting head must be done with the power off. If collector sparks are found to be large and the electric drill overheats during operation, stop using it and inspect it.
After the operation is completed, pay attention to safety, first turn off the power, the drill will stop completely, and then remove the workpiece from the tool. Freshly used drills can overheat and burn your skin, so don't touch them right away. Then store in a dry and clean place.
The foregoing represents the operation for changing the hand drill bit, as well as precautions before, during and after use. I hope you find it useful. For more information related to hardware tools follow me~
