1. The battery is broken. Within the unconditional return period Wireless Angle mill battery does not charge , return it. If the unconditional return wireless Angle mill battery does not charge , then apply for after-sales wireless Angle mill battery does not charge , return it for a refund.
2, the battery problem wireless Angle mill battery does not charge , when the battery itself is charged, it may be that the battery is bad, if shi if it is newly bought then you can find the business if it is newly bought, then you can find the business, directly solve the problem, If the letter is used for a period of time, if it is self-caused by use for a period of time, then a new battery needs to be replaced.
3, it is very likely that the lithium battery is not working, it is also possible that the lithium battery protection board works. Try another batteryLet's try.
4, charging Angle mill battery has electricity, turn on electricity can not turn for a while, stop for 3 seconds and turn due to the stator and rotor contact instability. The intermittent rotation of the charging Angle mill is caused by the unstable contact between the stator and the rotor, and the break of the stator and the rotor will lead to failure to work. The solution is to replace the connection line between the stator and the rotor and reconnect it.
5, lithium electric Angle mill a hard stop, there may be a problem with the lithium battery. Too low battery power or battery aging will cause insufficient battery output current, so that the protection device starts, resulting in shutdown. Solution
2, the socket and the lamp can not work properly to prove that it is broken, plug in the corneal machine according to the installation light is bright because there is electricity in the battery of the Angle mill, the conduction installation light represents the battery of the Angle mill backflow, so the socket and the lamp can not be positiveWorking often, plug in the corneal machine press the mounting light but light because the Angle grinder battery backflow. Angle grinder, also known as grinder or disc grinder, is a kind of grinding tool used for cutting and polishing FRP.
3. The fuse is broken. Angle grinder is the use of fiberglass cutting and grinding portable power tools, in its operation, the overvoltage fuse of the red light will be controlled by the fuse, showing the extinguished state, and when the fuse is broken, it will lose the ability to contain the overvoltage fuse red light, it will cause the red light to be lit.
4, the charger only shows the red light shining, the green light is not on, which usually means that the charger is being chargedDuring the process, the battery power is low. During charging, the charger usually shows a red light, and when the battery is fully charged, the charger will show a green light. Therefore, you don't need to worry about the charger or the battery having problems, just wait a while until the battery is fully charged.
5, may be the switch is broken when the operator is operating, pay attention to whether the accessories are intact, whether the insulated cable is damaged, whether the aging phenomenon. After checking, plug in the power supply before you can work.
6, the power supply is disconnected to repair the power supply. Angle grinder joints loose Check that all joints are correct. Switch contact failureGood needs to repair or replace the switch. Brush and commutator surface do not contact to replace the carbon brush. The switch contact is burned out and the switch needs to be repaired or replaced. Mechanical parts stuck check mechanical parts reassembly, etc.
1, so the wireless Angle mill battery does not charge problem is generally caused by poor contact Wireless Angle mill battery does not charge , such as poor switch contact wirelessThe battery of the Angle mill is not charged , and the line contact is poor.
2, may be caused by the following reasons: 1. Battery aging: If the battery is used for a long time The battery is not charged , aging may occur, resulting in a decrease in battery capacity and an inability to be fully charged. 2. Charger failure: If the charger fails, it may not charge properly, and the charger needs to be replaced. 3. Charging circuit fault: If the charging circuit is faulty, it may cause a failure to charge. You need to check whether the charging circuit is faultyNormal.
3, the battery problem, when the battery itself is charged, it may be that the battery is bad, if shi if it is newly bought then you can find the business if it is newly bought, then you can find the business, directly solve the problem, if it is used for a period of time if it is caused by the use of a period of time, then you need to replace the new battery.
The normal use of lithium batteries is one to two years, and power toolsWith the power type battery, its service life is shorter, in summary, it can almost be judged that this is a normal situation, it is recommended to replace the battery.
The battery itself, the quality is not good. Or there is poor contact, protection board failure and so on.
Lithium battery is so bad by you, the battery has been seriously overdischarged waste. It is recommended to buy a new battery replacement, and cherish the use of it, and then it has no power, do not try to over-discharge, but should go to charge.
