Maintaining your lawn mower is essential for keeping your yard looking its best. Sometimes, that maintenance requires turning your mower on its side. But which way is the right way? Turning it the wrong way can lead to serious engine problems. This comprehensive guide will walk you through the proper technique, precautions, and everything else you need to know.
Understanding the Risks of Improper Tilting
Tilting a lawn mower seems simple enough, but there’s a significant risk involved if you do it incorrectly. The main culprit? Oil. Lawn mower engines rely on oil to lubricate moving parts. When you tilt the mower the wrong way, oil can flow into areas where it shouldn’t be, like the carburetor or the cylinder. This can cause a variety of problems, including:
- Hydrostatic Lock: Oil entering the cylinder can prevent the piston from moving, potentially damaging the connecting rod or other engine components.
- Carburetor Flooding: Oil in the carburetor can clog jets and prevent the engine from starting or running properly.
- Spark Plug Fouling: Oil can coat the spark plug, preventing it from igniting the fuel-air mixture.
- Difficult Starting: Even if the mower starts, it may run poorly or emit excessive smoke.
Avoiding these problems requires understanding which way to tilt your specific lawn mower model.
The Golden Rule: Spark Plug Up!
The cardinal rule when tilting a lawn mower is to always keep the spark plug facing upwards. This simple guideline minimizes the risk of oil flowing into the wrong places. Imagine the engine as a container of oil. When you tilt it with the spark plug up, gravity works in your favor, keeping the oil where it belongs – in the oil pan.
This rule applies to most standard four-stroke lawn mowers, which are the most common type found in residential settings. If you’re unsure about your mower type, always consult your owner’s manual.
Step-by-Step Guide to Safely Tilting Your Lawn Mower
Before you even think about tilting your lawn mower, safety should be your top priority. Follow these steps to ensure a safe and successful maintenance session:
- Preparation is Key: Disconnect the spark plug wire. This prevents accidental starting while you’re working on the mower. Pull the wire straight off the spark plug; don’t yank on it.
- Fuel Management: Ideally, you should empty the fuel tank before tilting the mower. Gasoline is flammable and can spill when the mower is tilted, creating a fire hazard. If you can’t empty the tank completely, try to run the mower until it’s nearly empty.
- Choose Your Workspace: Select a flat, stable surface for working on your mower. A garage floor or driveway is usually ideal. Avoid working on grass or uneven terrain.
- Identify the Spark Plug: Locate the spark plug on your lawn mower engine. This is crucial for determining the correct tilting direction.
- Tilt with Caution: With the spark plug facing upwards, carefully tilt the mower onto its side. Use a controlled motion to prevent dropping or damaging the mower.
Two-Stroke Engines: A Different Approach
While the “spark plug up” rule generally applies to four-stroke engines, two-stroke engines require a slightly different approach. Two-stroke engines have a different lubrication system. The oil is mixed directly with the fuel. Therefore, the risks associated with tilting are less severe, but still present.
With a two-stroke engine, it’s generally safe to tilt the mower in either direction, but it’s still best practice to minimize the amount of tilting and to avoid leaving it tilted for extended periods. Emptying the fuel tank is even more crucial with two-stroke engines, as the fuel-oil mixture is more prone to spillage. Always consult your owner’s manual for specific instructions related to your two-stroke mower.
Dealing with Oil Spillage After Tilting
Even if you take precautions, oil spillage can sometimes occur. If you find oil in the wrong places, don’t panic. Here’s what to do:
- Clean the Spark Plug: If the spark plug is fouled with oil, clean it with a wire brush or replace it altogether.
- Drain the Carburetor: If oil has entered the carburetor, you may need to drain it. Consult your owner’s manual for instructions on how to drain the carburetor on your specific mower model.
- Allow Time for Drainage: After cleaning, let the engine sit for a while to allow any remaining oil to drain out of the cylinder and carburetor.
- Attempt to Start: After taking these steps, try starting the mower. It may take a few attempts for the engine to clear itself. If the mower still won’t start, you may need to seek professional assistance.
Alternative Maintenance Methods
While tilting a lawn mower is sometimes necessary, there are alternative methods for certain maintenance tasks that can minimize the need for tilting altogether. Consider these options:
- Lawn Mower Lifts: These devices allow you to lift the mower safely and securely, providing easy access to the underside without tilting.
- Long-Handled Tools: For tasks like cleaning the deck, consider using long-handled brushes and scrapers to reach difficult areas without tilting the mower.
- Professional Service: If you’re uncomfortable performing maintenance yourself, consider taking your mower to a professional service technician.
