Problem: A lawn mower engine, just like a car engine, needs regular maintenance for optimal performance; otherwise, it will probably develop problems.
Solution : The maintenance required to keep your mower in good condition is easy. With regular maintenance, your mower should provide several years of good service.
* Basic maintenance includes changing the spark plug, the air filter, and the oil.
Replace the spark plug - Leave it out of the engine until the work is complete so there's no chance the engine could start while completing the work.
- This is equivalent to turning the power off when working on electrical projects.
- When all other work is completed, replace the old spark plug with a new one.
Replace the air filter
- The casing for the filter might be located on the side or the top, depending on the model of lawnmower being serviced.
- Remove the casing for the filter and dispose of the old filter.
- Clean any debris from inside the casing with a brush, and install the new filter.
Change the oil
- Locate the drain plug; it is often underneath the mower's housing.
- Drain the oil, replace the drain plug and refill the oil reservoir.
Maintain the blade
- Be sure that when working with the blade, the spark plug has been removed so there is no chance the engine could somehow start.
- Periodically remove the blade and have it sharpened. When re-installing it, be sure the sharp edge faces the proper direction. In some cases the blade may need to be replaced.
- Check the underside of the mower deck often, and keep it as clean as possible for maximum efficiency.
Maintain the gas tank
When gas sits dormant in a gas tank for a long time, it can get stale. To counteract this, use a gas stabilizer or drain the gas tank and carburetor before storing the mower for the winter.
