Next‚ remove the oil filter using an oil filter wrench and replace it with a new one‚ lightly lubricating the gasket. Reinstall the drain plug‚ ensuring it’s snug but not overtightened. Finally‚ add the recommended amount of new oil (refer to your manual) using the oil fill cap. Check the oil level with the dipstick and run the engine briefly to circulate the oil.
Dispose of the used oil responsibly at a recycling center.
Air Filter Cleaning and Replacement
Maintaining a clean air filter is vital for optimal engine performance on your Craftsman YTS3000. Regularly inspect the air filter for dirt and debris. If it’s lightly soiled‚ you can gently tap it to remove loose particles or use compressed air‚ blowing from the inside out.

However‚ if the filter is heavily contaminated‚ it requires replacement. Locate the air filter housing and remove the cover. Discard the old filter and install a new one‚ ensuring a proper seal.
