Keep the vent free of foreign objects. Periodically clean the vent mechanism to remove dirt, bugs and leaves, and to keep all parts from sticking. Clean the button and vent door if they become difficult to open or close.
1. With the vent door closed (button up), spray clean water into the area under the button.
Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates. (00061a)
2. Blow low-pressure air in the same direction.
3. Using mild soapy water and a soft brush, remove dirt, leaves and bugs from vent duct and vent door.
4. Operate vent and repeat cleaning as necessary.
