1. Check the Intercept Micro Filter EACH and EVERY time you start and
finish vacuuming. A clogged and dirty filter restricts airflow, result-
ing in reduced suction, overheating and possible damage to the
vacuum.
2. While vacuuming throughout a building, stop every two hours or
as needed to shake out the Intercept Micro Filter (Figure A). Replace
with a new Intercept Micro Filter when necessary.
NOTE: Lift both Intercept Micro Filter and Micro Cloth Filter out at
the same time to avoid ripping the Intercept Micro Filter, especially if
it is full (Figure B).
Install an Intercept Micro Filter inside the Micro Cloth Filter. To install
an Intercept Micro Filter on the Sierra, slide the gasket of the Micro
Filter over the inlet on the inside of the top cap, then replace the cap
(Figure C).
3. Once a month (or more often if necessary) hand or machine wash
the Micro Cloth filter and let it AIR DRY. (DO NOT put it in the
dryer.)
4. For best results replace pleated dome filter every 6 months
(Figure D).
