Repairing your own lawn mower may sound really intimidating but doing your own lawn mower repair may be simpler than you think. Hopefully, this list can help you on your first attempt.
1. Safety first: Wear protective gloves, use eye protection and disconnect the spark plug. This is the first step you need to take before attempting to do anything with the lawn mower. Disconnecting the spark plug makes sure that the engine does not start while you are working on it. The gloves are for protecting your fingers from getting cut by sharp mower parts and prevent them from infected by dirt in the unfortunate event that you indeed got cut. Eye gear can protect your eyes from gasoline and metallic bits.
2. Determine if your lawn mower is a 2-stroke (oil and gasoline mixed) or a 4-stroke (separate oil and gasoline).
a. 2-stroke – Turn off fuel tap. Tip the mower anyway you want.
b. 4-stroke – Tip the lawn mower so the spark plug points to the sky.
3. Remove the spark plug and attach some string into the cylinder head while trying to undo the blade bolt/s to change a blade or blade disc.
4. Clogged air filter will increase consumption of fuel and lead to poor engine performance. Look out for symptoms of clogged air filter in the motor such as difficulty in getting it to start or sputtering and eventually stopping.
5. For 4-stroke models, it is recommended to change oil at least once a year.
Here are some things to remember when doing your lawn mower repair:
1. Be careful when changing blades, especially old ones. They have razor-sharp edges and you might get an infection from the rust and dirt when you get cut by them.
2. After operating, allow the machine to cool for a few minutes before touching the engine. Lawn mower parts may reach extremely hot temperatures and can burn your skin if you come in direct contact with them.
3. A new spark plug is often the solution when a lawn mower is not running. This may be one of the first things you would want to look at.
4. Check if you feel or hear some rattling in the mower. If that’s the case, a blade may be loose.
5. If you are not successful, have a trained technician take a look at it. It might just be worth the money to seek expert advice than to try mending it yourself, only to end up with a bigger mess.
