and a vacuum cleaner to remove dirt and debris.
Replace the filter cartridge if you find any holes in the
filter media.
9. Install the clean filter correctly, inserting the filter
carefully. Seat the filter by hand, ensuring it is
completely seated in the air cleaner housing before
putting the cover in place.
10. Install the service cover. Ensure that all mounting
bands, clamps, bolts, and connections in the entire
air cleaner system are tight. Check for any holes in
the piping and repair them if necessary.

Maintaining the Fuel System

Maintaining the Exhaust System

WARNING
could cause burns, resulting in serious injury.
• DO NOT touch hot parts and AVOID hot exhaust
gases.
• Allow equipment to cool before touching it.
Check the following when inspecting the exhaust system:
• Inspect the exhaust system manifold at the cylinder
head for leaks.
• Check that all remaining bolts and shields (if used) are
in place.
• Inspect the fasteners between the manifold and the
exhaust pipe to ensure they are tight and that no
exhaust leaks exist. Repair any leaks if necessary.
• Inspect the exhaust pipe connection for leaks. Repair
any leaks if necessary.
Using or operating the engine without a spark arrester
on the exhaust system (as defined in Section 4442) on
any land covered with forest, brush, or grass violates
California Public Resource Code, Section 4442. Also, the
code specifies that the arrester must be maintained and
in effective working order. Other states may have similar
laws. See Federal Regulation 36 CFT Part 261.52.
Maintaining the Fuel System
WARNING
gas are extremely flammable and explosive, which
could cause burns, fire, or explosion, resulting in
death or serious injury.
• Inspect the fuel system periodically.
• NO leakage is permitted.
• DO NOT operate the engine if you smell fuel.

Pressure Regulator

The pressure and regulator components have been
specifically designed and calibrated to meet the engine's
fuel system requirements.
If the regulator fails to operate or develops a leak,
repair or replace it with the proper OEM recommended
replacement parts. When inspecting the regulator, check
the following:
• Check for any fuel leaks at the inlet and outlet fittings.
• Check for any fuel leaks in the regulator body.
