2 – Routine Maintenance
Service the engine air cleaner
The engine air cleaner contains 2 filters:
 A primary filter that fits over the outlet tube, which creates a critical seal on the inside diameter of the filter
endcap
 A safety filter that fits inside the outlet tube, which creates a critical seal on the outside diameter of the filter
endcap
Replace the safety filter every 3 air cleaner services or every 2 years, whichever interval is less.
In very dusty or dirty environments, check the primary filter approximately once every 2 weeks. Use moisture-free
compressed air to gently clean the filter, as needed. Never remove the safety filter except to install a new one.
1. Turn OFF the system. Make sure the power switch on the front panel is in the OFF ( O ) position.
2. Wait for 30 seconds, then disconnect the battery’s negative (-) ground cable.
3. Remove the service panel on the generator side of the system.
4. Pull back the 3 clips, and remove the cover from the air cleaner. See Figure 19 .

NOTICE
Replace the air cleaner filters regularly. Never run the engine when the air cleaner filters are missing
or damaged. The air cleaner filters prevent airborne debris from entering the air inlet. Dirt or other
debris that enters the engine can cause premature wear and damage to engine components that is
difficult and expensive to repair.
