If you want to ensure that your lawnmower has as long a working life as possible, it is important to give its engine a regular tune up. For most lawnmower models, a tune up once a year is regular enough, and this is often performed in early spring – the starting of the mowing season. To get started, purchase a lawnmower tune up kit, otherwise make sure that you have a spark plug, air filter and oil on hand.

You will need to prevent fuel from getting into the carburetor whilst you are working on the lawnmower by closing the inline fuel shut-off valve. Then, drain the oil out of the lawnmower into an approved container (so that you can recycle it later) and fill the tank with fresh oil.

Use a socket and ratcheting wrench to remove the lawnmowers old spark plug, being sure to replace it with a brand new one. You can also remove the old air filter and replace it with the new one you purchased. Take note if your lawnmower uses a foam pre-filter, as you will need to add a couple of drops of engine oil to the filter before installing it.

Carefully inspect the blades of your lawnmower to see whether they need to be sharpened or even replaced. To remove the blades, disconnect the spark plug, place a block of wood in front of them and use a wrench to remove the nut holding them in place. You can sharpen the blades yourself or have a professional do them for you. Reattach them to the underside of your lawnmower and your tune up is complete.
