In order to keep your lawn mower in top notch condition, it’s vital to tune it up at the beginning and the end of the season. This is a brief self explanatory guide to do it yourself.
Introduction During summers, petrol powered lawn mowers are used frequently; so to keep it in good working condition, it is essential to tune it up before placing it back at the end of the season. This will ensure its parts are retained in good condition. Change oil, spark plugs, and air filters on mowers and put on elbow grease to dirty breaks. This should be done prior to storing them for the winter season so that it will speed up with a pull of the cord in the next spring. Investing an hour or two for maintenance or taking it to a professional for servicing, will enhance the performance of the machine and keep it in perfect condition for several years.
Here below are the servicing tips explained for a push mower in a step by step method. The same procedure can be employed for other small petrol powered lawn mowers, trimmers and snow blowers.
Step 1: Vacant the Petrol Tank If the petrol is there in the lawn mower, it can get hard in the winter, sticking up the carburetor and attracting corrosion. First of all, insert fuel additive to the tank, then after start the mower to dispense it through the system. Turn off the mower and allow the engine to calm down. Drain off excess petrol into a clean tin. Restart the lawn mower and run it till it halts. Redo till the fuel tank is totally vacant and the engine does not start.
Step 2: Detach the Spark Plug It’s crucial to detach the spark plug prior to carrying out the rest of the maintenance process. This will make sure that the mower does not kick-start accidentally and ensure your safety.
Step 3: Take Out the Blade Detach the blade by loosening the bolts that clasp it in place so that it is easier to change the oil and clean the base of the mower. When handling the blade, be sure to put on thick gloves. Take advantage of the opportunity to sharpen the blade when it is off.
Step 4: Emptying the Oil You will need to replace the oil if the mower has a four cycle engine (Mowers and trimmers also come with two cycle engines, wherein the oil is mixed with the petrol). To catch the oil that may spill out, you need to put a cover under the mower and have a pan ready. Place the mower on its side with the air filter and carburetor facing upwards, so oil and left over petrol don't disperse into them. Take out the oil tank plug and slowly shift the mower till the oil begins to spill into the pan. When all the oil has been vacated, replace the plug.
Step 5: Clean the Undercarriage To scrape off the grass and dirt layered on the mower deck, use a putty knife and wire brush. This puts off corrosion, clears the passageway to the ejection shaft, and permits the aeromechanics of the deck to work as designed. Reattach the sharpened blade after the deck is cleaned. Once you are done with, turn the mower in straight position, fill the oil tank with fresh SAE 30 or 30-weight oil, and recycle the used oil at a service station. Avoid using thicker oil like 10W-40.
Step 6: Replace the Air Filter Impure air filter holds back the engine from burning petrol competently by limiting the air required for burning. A lawn mower with a paper filter should be changed with a new one, and let the paper edges face outwards. Take it out in case it’s an oil-soaked sponge filter, and wash it thoroughly with soap and clean water, let it to dry entirely, and add a little bit of clean oil to it prior to placing it back. With a screwdriver or Popsicle stick clean the cooling fins of mud and debris.
Step 7: Change the Spark Plug Take off and change the spark plug, using a socket pull with a spark-plug socket, which has a neoprene lining to guard the plug's porcelain shell. For a couple of dollars, you will get a new spark plug, which will ensure better performance and a smooth launch coming spring season.
