POST-MOTOR FILTER MAINTENANCE
18. Post-motor filter is located in the right side wheel. Hold the
centre of the wheel and twist the wheel cover anti-clockwise.
19. With the wheel cover off the post-motor filter is easily removed.
20. Check the post-motor filter for discoloration.
21. Don't wash the filter with water*.
* IMPORTANT: The exhaust filter is designed to offer long
life with no maintenance. The filter should be checked
periodically and when heavily discolored it should be
replaced. Please do not wash, scrub or brush the filter as
this will damage the delicate filter media.
NOTE: Clean the pre-motor filter every time the dirt
container is emptied and replace the post-motor filter
every 12 months.
