Lubricate all exposed ends of cables from oil can. Check all controls for freedom and see that nipples work freely in control levers. Remove any tight nipples from levers, ease, lubricate and refit.

Any cables showing signs of sticking within the outer casing must be detached from the levers and oil worked down into outer casing by feeding in oil from can and working casing up and down on inner cable whilst cable is held as upright as possible.
