- The air filter should be replaced under normal operating conditions after 30,000 km. In conditions of increased dust, more frequent replacement is required.
- The filter element can be cleaned to a certain extent by blowing it from the inside out with an air hose (Fig. 137). However, this only removes the outer layer of dust and the element will still need to be replaced after some time. Never wash the element with any liquids.
