Before you rub down the new blades, dampen the surfaces of the blades with pump oil. Keep the blades
moistened with pump oil while you rub down the blades.
Place the blades on a flat metal work surface when you rub them down.
Use a piece of emery paper to rub down the blades; the piece of emery paper must be larger than the blade
to ensure that you obtain an even finish.
Apply an even pressure over all of the blade when you rub it down.
When you have finished, seal all waste (emery paper, old blades and any paper or cloth which you have used

the bag.
Dispose of the waste bag at a licenced waste disposal facility.
