General Maintenance

Model MMV Rev. 10/11
An indicator light (1) on the front dash panel will illuminate to alert the
operator when it senses restricted air flow to the engine. This indicates the
air filter(s) need servicing. NEVER operate the vehicle without the air
cleaner assembly and both filters in place.
A. Element: Change
(As Restriction Indicator Indicates or
Every 500 Hour Intervals)
Outer Primary Element
All air cleaner manufacturers agree that attempting to clean or wash an
element increases the chance for element damage. It is highly
recommended that you consider the value of cleaning an element against
the risks which could lead to engine damage. Adopt the policy that all
elements should be replaced with new
and not cleaned.
Inner Safety Element
An inner safety element should never
be washed or reused. Always install a
new element. Replace inner safety elements after every third primary
element change. DO NOT remove an inner safety element until you have
thoroughly cleaned the inside of the air cleaner canister. This will prevent
dirt, which could damage the engine, from entering the induction manifold.
2. Air Cleaner
CAUTION: NEVER run the engine with only the inner
safety element installed. Severe engine damage will result from
dust entering the engine.
