Periodic Maintenance Procedures
Clean Air Cleaner Element
Note that a typical air cleaner is shown in
Figure 5-12 and Figure 5-13 for illustrative
purposes only.
The engine performance is adversely affected
when the air cleaner element is clogged with dust.
Be sure to clean the air filter element periodically.
1. Unlatch and remove the air cleaner cover
(Figure 5-12, (1)).

Figure 5-12
2. Remove the element (Figure 5-12, (2)) (outer
element if equipped with two elements).
A
CAUTION
FLYING OBJECT HAZARD!
• ALWAYS wear eye protection when
servicing the engine and when using
compressed air or high-pressure
water. Dust, flying debris, compressed
air, pressurized water or steam may
injure your eyes.

PERIODIC MAINTENANCE
3. Blow air (Figure 5-12, (3)) through the element
from the inside out using 42 - 71 psi
(0.29 - 0.49 MPa; 3.0 - 5.0 kgf/cm
compressed air to remove the particulates. Use
the lowest possible air pressure to remove the
dust without damaging the element.
4. If the air cleaner is equipped with a double
element, only remove and replace the inner
element (Figure 5-13, (1)) if the engine lacks
power or the dust indicator actuates (if
equipped).

5. The inner element should not be removed when
cleaning or replacing the outer element. The
inner element is used to prevent dust from
entering the engine while servicing the outer
element.
