NOTE
• Use cotton swabs to clean the rollers in locations that are too narrow for
your fingers, such as a, b, j, n, o, and p.
• Rollers in positions b, d, e, k, and p are turned by the roller in position
e. Turn the roller in position e to wipe the rollers.
• Rollers in positions m and n comprise two rollers each, an upper roller
and a lower roller.
• Do not force the rollers if they will not turn. In this case, wipe dirt only off of
the exposed area.
