Steps for Changing Oil in Lawn Mowers :
Step 1. Prepare for the Oil Change
They say that ‘failure to plan is planning fail.’ As such, there a couple of plans and things that you need to do before draining any old oil from the lawn mower.
- Warm the mower’s engine. This is done by running it for about 15 minutes. This speeds up the process of oil change by making it flow more freely thus making it easier to remove all the old oil from the engine.
- Turn it off and remove the mower’s spark plug.
- Clean the oil fill area. Use a clean towel or an air compressor to do this.
- Prepare the oil drain pan to catch the old oil. A normal container can also be used for this. Position the drain pan on the side of the lawn mower that you’ll tip to drain the oil.
Step 2. Dump the Old Oil
After the above preparations, the mower is now set to have its oil drained.
- Raise the mower’s wheels onto slabs of timber to increase clearance so that your hands can reach under the mower. Take care not to hurt your hands in the process.
- Unfasten and get out the oil fill cap.
- Tip the mower on its side and extract all of its oil. Leave it in that position for a couple of minutes to ensures that all the old oil drip out.
Step 3. Replace the Filters
If your mower’s oil filters are dirty, replace them. Simply loosen it with a wrench. Be ready for oil spillage from the filter ports on the engine.
Wipe the mounting ring on the engine and the engine compartment. Dispose off the old filter and use oil to lubricate the gasket of the new filter. Screw the new filter on.
Once the gasket and the casing meet, hand-tighten the filter until they make solid contact.
Step 5. Refill the mower with new engine oil
Your mower is now ready to have its engine refilled. Check the user’s manual to determine that exact amount of oil that the mower needs.
In most cases, mowers require between two-third and three-quarter a quanta of oil. This oil level is normally between the two holes on the dipstick.
Step 5. Add engine oil slowly until it reaches the required level
Stop severally as you fill the oil and use the dipstick to check its levels. Ensure you don’t overfill it. Over-filling the oil on the mower’s engine is as bad as under-filling it.
Step 6. Replace the oil cap
Be keen not to over-tighten the drain plug. If it’s made of plastic, over-tightening can split it in two and if it’s metallic, you can damage the thread on the sump.
Reconnect the spark plug wire and you’re good to go. It’s that simple, your mower’s oil change is now effected.
Step 7. Recycle the Old Oil
You can take the container with the old oil to the nearest approved oil-recycling dealer for recycling. Never dump old oil onto the ground, lawn or down a drain since it’s a powerful pollutant and can cause untold damage to the ground water and streams.
