(5) all cups, including on the ratchet mechanism, sliding bearing oil cup oil cup oil Cup and spin-lock box, at the junction of main activities according to the use of lubricated at the right time.
(6) regularly check that the rope is loose, buffer spring stretching, identify problems and deal with.
