While it’s a straightforward process, following the correct steps and using proper safety precautions are crucial. This article will provide you with a step-by-step guide to ensure you perform the oil change safely and effectively.
Step 1: Gather Your Supplies
Before you begin, make sure you have all the necessary tools and materials:
- New Engine Oil: Consult your Husqvarna lawnmower manual to determine the correct type and viscosity of oil for your model.
- Oil Drain Pan: A large, flat pan to catch the old oil.
- Oil Filter Wrench: If your Husqvarna model has an oil filter, you’ll need a wrench specifically designed to remove it.
- Funnel: For safely pouring the new oil into the engine.
- Gloves: To protect your hands from the oil.
- Rag: For cleaning up any spills.
- Safety Glasses: To protect your eyes.
- Work Area: Find a level surface for working on your mower.
Step 2: Prepare Your Mower
Safety First
- Before starting any work on your Husqvarna lawnmower, always disconnect the spark plug wire to prevent accidental ignition.
- Ensure the mower has completely cooled down, especially if it has been used recently.
Prepare the Work Area
- Find a level surface, preferably concrete or pavement, for easier drainage of the old oil.
- Position the mower so that the oil drain plug is easily accessible.
Step 3: Drain the Old Oil
Locate the Oil Drain Plug
- Consult your Husqvarna lawnmower manual for the specific location of the oil drain plug on your model. It’s usually located on the bottom of the engine housing.
- Using a wrench, loosen the oil drain plug, but don’t remove it completely just yet.
- Important: Once you’ve loosened the plug, be prepared for the oil to start draining immediately.
Drain the Oil
- Position the oil drain pan directly below the drain plug.
- Once the oil has stopped draining, completely remove the oil drain plug and allow the remaining oil to drain into the pan.
- Clean the plug thoroughly with a rag and reinstall it.
Step 4: Change the Oil Filter (If Applicable)
Check for an Oil Filter
- Not all Husqvarna lawnmower models have oil filters. Check your manual to see if yours does.
- If your mower has a filter: The oil filter is usually located near the top of the engine housing, often near the oil fill cap.
Remove and Replace the Oil Filter
- Locate the oil filter: Identify the filter and use an oil filter wrench to loosen and remove it.
- Inspect the old filter: Be careful when removing the filter, as oil may still be present inside.
- Replace the filter: Install the new oil filter, ensuring it’s securely fastened and tightened. Avoid over-tightening, as this can damage the filter.
Step 5: Refill with Fresh Oil
Locate the Oil Fill Cap
- Consult your manual for the specific location of the oil fill cap. It’s often located on the top of the engine housing, near the oil filter (if your model has one).
Add New Oil
- Use the funnel to pour the correct amount of oil into the engine.
- Refer to your manual for the recommended oil capacity for your model. Avoid overfilling the crankcase, as it can damage the engine.
Step 6: Check for Leaks
Inspect the Drain Plug
- Carefully examine the oil drain plug and surrounding area for any leaks. Tighten the plug further if necessary.
Inspect the Oil Filter (If Applicable)
- If your mower has an oil filter, check the filter connection for leaks.
Wait and Check Again
- Let the mower sit for a few minutes to allow the oil to settle.
- Recheck for leaks again.
Step 7: Dispose of the Old Oil Properly
Environmental Responsibility
- Never pour used motor oil down the drain or into the ground. This pollutes the environment.
- Locate a proper disposal site: Contact your local waste management or recycling center to find out where you can safely dispose of used oil. Many auto parts stores also have oil recycling programs.
Cleaning Up
- Clean up any spills immediately with a rag and soap and water.
- Wash your hands thoroughly after completing the oil change.
Step 8: Start and Run the Engine
Reconnect the Spark Plug Wire
- Once you have ensured everything is secure and clean, reconnect the spark plug wire.
Start the Engine
- Start the mower and let it run for a few minutes. Check for any leaks or unusual noises.
Important Note: It’s normal for the oil pressure light to illuminate briefly when the engine starts. If it stays lit, there could be a problem with the oil pressure system.
