The Fourth Step:
1.；The aircraft starts to land at a speed of 1m/s, and the cable needs to be in a straight state. According to
the actual factors such as wind speed and landing speed, the winch control knob can be switched to 4th
gear or above while retracting the cable. Pay attention to the winch window to prevent cable winding.
2.；When the aircraft descends nearly to 5m above the ground, adjust the winch control knob to 0 position
to turn it off, long press the cable power button for 3s to turn off the ground power, prevent the high-
voltage cable from hurting the valuables and the human body. When the aircraft landing on the ground, and
propellers stop turning, power off the drone.
3. Turn off the main power switch,unplug the on-board power input cable. Then turn on the main power and
the winch control switch, retract the cable to the box, then turn off the main power.
4.；Turn off the main switch of the equipment or generator, unplug the 220Vac input cable and lock the box.
In order to reduce the risk of winch cable winding, it is required that the cable outlet position should
be in the middle of the winch when the aircraft is hovering in a high altitude.
The cable needs to be in a straight state while being retracted.If the cable is at the ends when being
retracted, the cable need to keep perpendicular to the rail to avoid cable winding.
- The cable should be in the middle of the winch, reduce winch eccentric force.
- The cable needs to be in a straight state while pulling or being retracted.
- If the cable is at the ends when being retracted, the cable need to keep perpendicular to the rail to avoid
cable winding.
- Tilt state is not allowed, cable is not guaranteed.
