Miner lamp size

Miner's lamp charging and use method
1.Press the switch button on the headlamp, the first time the main light source is on, press the second time for the secondary light source, press the third time to turn off the light.
2.Hold the hook of the lamp cap into the helmet bay and then secure it with the belt through the slot of the battery case to the waist position.
3.Through the switch button to adjust the light to their desired brightness
4.When the power is low , the main light source will automatically switch to the secondary light source, not stay in the underground for a long time, should be charged to the lamp.
5.Insert the hole in the lamp cap on the pillar of the charger and turn it 180 degrees clockwise to allow the contact to be fully charged. When fully charged, this time the lamp can be rotated 180 degrees counterclockwise to the lamp out.
6.When the red light in the lamp is lit, it indicates that it is charging. When the green light is on, it indicates that the battery is full
7.Lamps are charged every time after use to ensure that the battery is always in full power state, after a full charge can be used within a year at any time.

Simple fault handling method

Faultphenomenon Failure analysis Approach
Can not turn on the lights after pressing the button The battery is exhausted or Pls charging the lamp

Lamps and other failures, please contact us in time.

Note
1.KL4LM (K) intrinsically safe miner's lamp from factory has been charged to about 50%, will be filled with a charger before use.
2.Please use this miner lamp’s charger or charging rack for charging, if use of other types of charger charging will damage the lamp.
3.If you do not use it for a long time, follow the steps below to perform maintenance, complete charge → full discharge → 2 hours charge maintenance operation.

Safety warning
1.Miner lamp at work can not be directly on the human eye, or strong light will damage people's eyesight.
2.Do not disassemble the parts of miner lamp at random. It is forbidden to use miner lamp with the missing parts in hazardous locations. Otherwise, it will affect the safety and reliability.
3.Donot beat the miner lamp.
4.Do not charge the miner lamp in hazardous locations.
5.Do not put miner lamp near or put into the fire .
6.It is forbidden to remove miner lamp or replace the parts in the underground. The maintenance and maintenance of miner lamp shall be carried out in a safe environment.Can not arbitrarily change the structure and parts of the lamp.
7.Scrapped miner lamp are centralized ,Not arbitrarily discarded.
