With the reel mouth facing upwards, remove the nut on the reel, remove several other small parts (in order), and then untie the remaining knots or rope segments on the plastic rope reel. For the starting rope to be installed, burn the rope end at the end of the winding disc, then pass the thin wire or iron wire (10- 15 cm long) through the rope-passing hole of the plastic winding disc, and rotate the plastic disc to align the rope-passing hole with the iron disc of the starting disc.
