so that it can be recycled. Never discard in a dustbin, in the ground or in sewers.

of oil will be reduced and the engine will be damaged.

The air filter MUST remain perfectly clean. A dirty filter, caused by a poor fitting or a poor

6. The urethane foam [(e) Fig. 33]:
— Wash and clean urethane foam using a special detergent for air filter. Immerse the element in
a solution of lukewarm water and non-foaming household detergent, then rinse, or;
— clean it in a non-flammable solvent;
— then let it dry completely. Dip the element in clean engine oil and squeeze it to remove excess
oil. If the amount of oil left in the foam is excessive, the engine will smoke during the next
starts.

a hard surface to drop dirt, or blow with air compressed from the inside to out. Never brush
the element, the brushing would penetrate the impurities inside the fibers. Replace the paper
