To clean a spray nozzle:
- 1. Remove the nozzle from the spraybar.
- 2. Soak the nozzle in a mineral-dissolving solvent to help loosen deposits.
- 3. Remove deposits from the nozzle with a wire brush.
- 4. Install the nozzle in the spraybar.
Checking The Engine Air Cleaner
The engine air cleaner is equipped with an indicator that shows a red signal when the main element should be serviced. If the red signal is locked in view, the main elements should be cleaned or replaced as soon as possible to prevent possible engine damage.
The main element should be replaced after six cleanings or one year of use, whichever occurs first. (See the Service Manual for cleaning procedures.) Change the safety element every third time the main element is cleaned or replaced. Although it is possible to clean the safety element using the procedures described for the main element, it is not recommended except in an emergency situation. Maximum engine protection is achieved by replacing the plugged safety element with a new element.
