hours at the latest.

The filter cartridge should either be replaced or, depending upon the
degree of contamination, cleaned or checked, as follows:
Dry Contamination:
• Use compressed air to blow through the filter cartridge from the inside

Moist or Oily Contamination:
• Replace the filter cartridge.
Checking the Filter Cartridge:
• Check filter cartridge's gasket surface (d) for damage.
• Check the filter cartridge for cracks or any other type of damage to the
paper filter by holding it inclined towards the light or by shining a light
source through it.
NOTICE: If there is the slightest damage to the paper filter, do not re-
use.
• Re-assemble the filter cartridge in reverse order.
