A part of the review has been auto-translated.
When the battery is inserted, nothing happens. It's normal. Press the small red button at the foot of the handle for 3 to 5 seconds long. One of the green LEDs lights up and we hear a beep that confirms that the pruning shears have been turned on. Now we do 2 to 4 consecutive quick pulls on the trigger and the device goes into action mode, confirmed by double beep and blade opening. We are now ready to work. A pull on the trigger closes the blade, and eventually cuts the branch, then when released, the blade opens again. 4 widths of the blade can be selected depending on the diameter of the branches to be cut. To do this one or several short press on the small red ON-OFF button near the LEDs. With each short press of this button the number of green LEDs lit changes, symbolizing one of the 4 degrees of opening to the next pressed--released on the trigger; 1 LED = mini, 4 LEDs = max. At the end of the work, to keep the blade closed, just keep the trigger pressed for about 6 seconds until the beep confirming that the blade will not open again when releasing. All that remains is to turn off by a long press on the red ON-OFF button. There, no beep but the last green LED dims. The battery can then be disassembled for recharging or storage.
I received this item within eight days. The packaging is not the best, so I photographed the package from start to finish, just in case something went wrong. The batteries, as shown in the photos, are low charged. After 2 hours and 30 minutes they got the full charge of 21 V. The blade opening does not show a pruner for cutting 5 cm branches. I tried it on thin branches up to about 2 cm, it worked satisfactorily. I will know the battery life after extended use. Thanks to the supplier
