Lightweight Cordless Drill

Product introduction

How to use the lightweight cordless drill ?

The electric hand drill is a commonly used drilling power tool powered by AC power supply or DC battery. If you don't use the electric drill correctly, you may hurt others or yourself. So what should you pay attention to when using the electric drill correctly?

First, ensure the safety of the circuit: Before use and during use, ensure that the circuit is normal, the wires connected to the power supply are not damaged, and there is no leakage of electricity. If there are exposed wires, wrap them with insulating tape before use.

Second, ensure the safety of the switch device: turn off the switch when the hand drill is not in use, so as to prevent the sudden rotation of the power drill next time and hurt people.

Third, check before use: Before using the electric drill, turn on the switch after powering on and idle for 0.5 to 1 second to check whether the transmission part is flexible, whether there is any abnormal noise, whether the screws are loose, and whether the spark of the commutator is normal.

Fourth, the control method must be correct: when drilling holes with a hand electric drill, hold both hands tightly, and try not to operate with one hand.

Fifth, the drill bit is selected correctly: the drill bit of the electric drill cannot use a drill bit with a gap, and the downward pressure should not be too large when drilling to prevent the drill bit from being interrupted.

Sixth, the drilling force should be moderate: when the electric hand drill is drilling an object, the drilling force should not be too large, and no force should be used to prevent the drill bit or wire tap from flying out and hurting people.

Seventh, troubleshoot in time: If you find that there is a large spark on the commutator and the electric drill is overheated during the use of the hand electric drill, you must stop using it and carry out inspections, such as removing dirt, replacing worn brushes, and adjusting the spring pressure of the brush holder. use.

Workshop

Vertical skills and methods of hand electric drill

1. The electric drill should be held firmly without swinging; the electric drill should be perpendicular to the object to be drilled (keep at 90 degrees).

2. Control the rotation speed first slow and then normal (if there is this function), before drilling, first make a small hole on the object to be drilled, so as to ensure the process.

3. Only when the workpiece clamping level is accurate can it be perpendicular to the spindle of the drilling machine. When drilling, first locate the center hole. When the hole diameter is large, first drill a small hole and then use a large drill to expand the hole. The drilling chip speed and feed speed are properly matched. The clearance of the main shaft of the vibration drilling machine is normal, and it is basically vertical.

What to pay attention to when using a hand electric drill

1. Check before use. Before using the electric drill, check whether the insulation of the wire is good. If the wire is damaged, wrap it with tape. It is best to use a three-core rubber cord and ground the case of the electric drill. Check whether the rated voltage of the electric drill is consistent with the power supply voltage, and whether the switch is flexible and reliable.

2. Requirements for the use of hand drills. After the electric drill is connected to the power supply, it is necessary to use an electric test pen to test whether the shell is charged, and it can only be used if it is not charged. When you need to touch the metal shell of the electric drill during operation, you should wear insulating gloves, wear electrician insulating shoes and stand on the insulating plate. When disassembling the drill bit, use a special key, and never hit the drill chuck with a screwdriver or hand hammer. When installing the drill bit, pay attention to keep the drill bit on the same axis as the drill holder to prevent the drill bit from swinging back and forth when turning. When using a hand drill, the drill bit should be perpendicular to the drilled object, and the force should be uniform. When the drill bit is stuck by the object, stop drilling, check whether the drill bit is too loose, and re-tighten the drill bit before use.

3. Drilling. The drill bit used must be sharp, and the force should not be too strong when drilling to avoid overloading the electric drill. When the speed suddenly drops, the pressure should be released immediately. If the electric drill stops suddenly, cut off the power immediately.

4. Find problems in time. When drilling, if the temperature of the bearing is too high or the sound of the gear and bearing is abnormal, it should be stopped immediately for inspection. If the bearings and gears are damaged, they should be replaced immediately.

5. Move the position correctly. When moving the electric drill, you must hold the handle of the electric drill, do not drag the power cord to move the electric drill, and prevent the power cord from being scratched and crushed at any time.

6. Safe storage. After the drilling is completed, the wire should be wound on the electric drill and placed in a dry place for the next use.
