4. Cleaning air filter element
The maximum intake resistance of diesel engine must be inspected when it operates

allowable limit, clean or replace filter element.
Note: never operate the engine when no air filter is provided, or dust and
impurities would enter into diesel engine and cause early wear of engine.
