Overservicing
Overservicing occurs when an air filter element is removed
for cleaning or replacement before it is necessary. Each time
the filter is removed a small amount of dirt and dust could
fall in the intake system. This accumulated dirt can cause a
dusted engine. It only takes a few grams of ingested dirt over
the normal service life of an engine to cause a dusted engine.
Do not clean the element, but replace with a new element
only. Cleaning used air filter elements, through improper
cleaning procedures, can get dust on the inside of the filter
causing dirt ingestion and engine failure.
It is important to note that whenever an air filter element is
cleaned by any method, the person or company performing
the cleaning assumes responsibility for the integrity of the
filter from then on. The warranty for air filters expires upon
cleaning or servicing in any manner because the condition of
the filter after servicing is completely out of the filter manufac-
turer’s control. Therefore, on a dust ingested engine failure,
there will be no warranty consideration if the air filter element
has been cleaned or serviced in any manner.
A partially dirty air filter element works better than a new
element. Therefore, a dirty filter element is not bad for the
engine unless it is excessively restricting the air flow and
engine performance is affected. The reason is simple. The
media in the filter must be porous to allow air to pass
through it. When dirty air passes through the filter, the dirt
plugs some of the holes in the media and actually acts as
part of the filter media. When the next round of dirt enters,
the first dirt helps filter out even smaller particles making the
filter more efficient at stopping dirt from entering the engine.
This is referred to as barrier filtration.
Of course, at some point the filter media becomes too
clogged to allow air to pass.
The mowing conditions will determine the frequency of air
filter element changing.
Air Restriction Indicator
Some mowers have engines with an air restriction indica-
tor installed in the air cleaner. Figure 4-12
Replace the element whenever the restriction indicator
reaches the change filter red line. Check the indicator daily
and replace element as needed or annually whichever occurs
first.
Reset the indicator by pushing in on the yellow button after
each element change. Figure 4-12
General Engine Maintenance
Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine Owner’s
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
engine manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
