Note - Engine Air Filter Maintenance Instruction
The ITG foam air cleaner element supplied as part of this package requires the following maintenance
procedure to ensure efficient results:
1. The new filter element must be oiled before use (see installation procedure).
2. The filter must be cleaned regularly, dependent on operating conditions. Cleaning can be carried out
using a bath of petrol, or with liquid detergent and warm water. Rinse in warm water after cleaning. Do
not use hot water. After cleaning, the filter should be allowed to dry thoroughly. Do not use a high
pressure air line, or a hot air blower.
3. After cleaning, the filter must be re-oiled. Use the ITG dust retention aerosol to spray a good covering of
oil all over the element, then gently massage the oil into the depth of the foam.
IMPORTANT: If the filter is not oiled thoroughly some fine dust may work through the filter.
