for any holes or tears in the paper. Also check gaskets for
cuts or tears. Do not attempt to use a damaged element
which will allow abrasive particles to enter the engine.
3. Reinstall the dust cup. Make sure it seals all the way
around the air cleaner body, then tighten the clamps.

4. Check all fittings and clamps periodically for tightness
and inspect hoses for holes or cracks.
5. Periodically check the intake hose for signs of ingested
dust. Locate and repair the source of ingested dirt.
6. Never operate a machine without an air filter installed.
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 element, 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 their 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
These units have an air restriction indicator installed in the air
cleaner. Figure 6-4
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 6-4
Fuel evaporation system filter
Some Hustler ® X-ONE i mowers have a fuel evaporation
system filter. This filter must be checked and replaced every 500
hours or annually whichever comes first. Figure 6-5
Fuel & evaporative system line routings
There are two rubber hoses that are connected to the fuel
tanks. One is the fuel hose that is part of the fuel system. The
other is the vapor line that is part of the fuel evaporative system.
The fuel hose connects to the outer most fitting with the
fitting barb pointed toward the inside of the frame. It connects
the fuel tank to the fuel shutoff valve. Figure 6-6
The vapor line connects to the inner fitting with the fitting
barb pointed towards the rear of the frame. It connects the fuel
tank to the engine’s vapor port. Figure 6-7
