Procedure
1. Loosen the eyebolt and clamp to remove the air
cleaner cover.
2. Remove the wing nut and slide the air cleaner
element from the threaded rod.
3. Tap the element lightly against a flat surface to
dislodge loose surface dirt. Do not clean the
element in any liquid or use compressed air as
these will damage the filter element.
4. Wipe the cover and base with a clean rag to remove
any dirt.
5. Ensure tight clamps at the inlet/outlet connections.
6. Install the air cleaner element on the threaded rod.

3.6 Exhaust System
Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
WARNING
Inspecting the exhaust system. Carbon monoxide can
cause severe nausea, fainting, or death. For the safety of
the vehicle’s occupants, install a carbon monoxide detector.
Consult the coach builder or dealer for approved detector
location and installation. Inspect the detector before each
generator set use. In addition to routine exhaust system
inspection, test the carbon monoxide detector per the
manufacturer’s instructions and keep the detector operational
at all times.
Inspect the exhaust system components (exhaust
manifold, exhaust line, exhaust clamps, and muffler) for
cracks and corrosion.
D Check for corroded or broken metal parts and replace
them as needed.
D Check for loose, corroded, or missing clamps and
hangers. Tighten or replace the exhaust clamps
and/or hangers as needed.
D Check that the exhaust outlet is unobstructed.
D Check the exhaust gas color. If the exhaust is blue or
black, contact your local distributor/dealer.
D Visually inspect for exhaust leaks (blowby). Check
for carbon or soot residue on exhaust components.
Carbon and soot residue indicates an exhaust leak.
Seal leaks as needed.
D Ensure that the carbon monoxide detector is (1) in the
vehicle, (2) functional, and (3) energized whenever
the generator set operates.
