   Thoroughly inspect the dirty primary filter to ensure that there is no damage in the filter. If there is any sign of damage in the filter, discard the filter.
   • Never wash, brush or knock elements.
   • If using compressed air, the air must be directed from the inside (clean side) of the filter. The air must be dry and the maximum pressure allowed is 5 bar (72.5 psi), the nozzle should be 1/8 in. to 1/4 in. and held no closer than 50 mm (2 in.) from the filter media.
   • Ensure that contaminant does not enter or come in contact with the clean side of the filter.

2. After the cleaning process is complete, inspect the filter again to ensure that no damage occurred during cleaning. If there is any sign of damage in the filter, discard the filter.

   Never clean the secondary filter (safety). Replace if dirty.

   Never run engine without both filters in place.
