Generac Power Systems R100 Operator's Manual page 12

Do not dump oil containers or discarded engine oil into rubbish boxes or onto the ground. For the sake of environmental
protection, we suggest you take in discarded engine oil with a closed container and bring to local recycling station.
2. Maintenance of air filter
A dirty air filter can restrict air flowing into the carburetor. To keep the carburetor in good working condition, please service
the air filter periodically (clean air filter element after 20h of use). If the engine is being operated in an extremely dusty area,
clean the filter more often.
Never clean the air cleaner filter with gasoline or low flash-point detergents, or explosion may happen.
Never run the engine without an air filter because dirt and dust entering the engine can speed up engine wear and cause damage.
