Preparing Your Craftsman 6.75 Lawn Mower for Starting
Before you even think about pulling the starter cord, it’s crucial to prepare your Craftsman 6.75 lawn mower for a smooth start.
Checking the Fuel
Checking Fuel Level
The first step is to check the fuel level. Your Craftsman 6.75 lawn mower will likely use gasoline, so make sure there’s enough fuel in the tank. If the level is low, you’ll need to refill it. You can usually find the fuel tank cap on the side of the mower.
Using Fresh Fuel
It’s important to use fresh gasoline that is no older than 30 days. Older fuel can gum up the carburetor, making it difficult to start the engine. You can use a fuel stabilizer to help keep your fuel fresh for longer.
Checking the Spark Plug
The spark plug is responsible for igniting the fuel-air mixture in the engine. You’ll need to remove the spark plug to check its condition.
How to Check the Spark Plug
Use a spark plug wrench to remove the spark plug from the engine cylinder. You’ll find the spark plug under a small metal cover, usually on the side of the engine. Once removed, inspect the spark plug for wear, damage, or fouling. If the spark plug looks worn or dirty, you’ll need to replace it.
How to Test the Spark Plug
To test the spark plug, you can hold it against a metal surface and crank the engine over. If there’s a spark, the spark plug is functioning correctly.
Checking the Air Filter
The air filter cleans the air that enters the engine. A dirty or clogged air filter can restrict airflow, making it difficult to start the engine.
How to Clean the Air Filter
To clean the air filter, remove it from the air filter housing and tap it against a hard surface to remove dirt and debris. If the air filter is very dirty, you can wash it in soapy water and let it air dry completely.
When to Replace the Air Filter
If the air filter is beyond cleaning or if it’s more than 2 years old, it’s time to replace it.
Checking the Oil
The oil lubricates the moving parts of the engine. If the oil level is too low, the engine can overheat and seize up.
How to Check the Oil Level
Use the dipstick to check the oil level. The dipstick is a metal rod with a handle, and it’s located on the side of the engine. Remove the dipstick and wipe it clean. Insert it back into the dipstick tube and pull it out again. The oil level should be within the “full” markings on the dipstick.
How to Add Oil
If the oil level is low, add the recommended type of oil to the engine. You can find the recommended oil type in your Craftsman 6.75 lawn mower owner’s manual.
