CHANGING THE POSITIVE PRESSURE VENT (PPV) AIR FILTER
- While holding the PPV cover unscrew the 10mm centre bolt.
- The cover and internal air filter will dropdown.
- If the air filter does not drop down carefully use a hacksaw blade or large knife to loosen the seal.
- Before replacing the air filter, line both sides of the black rubber with Vaseline or all-purpose grease. This will help it from sticking and make it easier to remove next time.
- Refit air filter and PPV cover.
