Starting a lawn mower might seem like a daunting task for beginners, especially if you’ve never handled one before. Yet, with the right guidance, it can be a straightforward process. This article aims to provide an in-depth, step-by-step guide to help beginners start a lawn mower safely and efficiently. We’ll cover different types of lawn mowers, the necessary pre-start checks, and common troubleshooting tips.
Understanding Different Types of Lawn Mowers
Before diving into the actual process of starting a lawn mower, it’s important to understand that there are different types of lawn mowers, each with its own starting procedure. The two main categories are:
Gas-Powered Lawn Mowers: These are the most common types, known for their power and efficiency, especially on larger lawns. They typically have either a pull-cord or an electric start.
Electric Lawn Mowers: These can be corded or battery-operated. They are quieter and easier to start compared to gas mowers but are generally less powerful.
Pre-Start Preparations
Regardless of the type of lawn mower you own, certain pre-start checks are crucial. These checks ensure that your lawn mower operates efficiently and safely. Here’s what you need to do before starting your mower:
1. Check the Fuel Level (Gas-Powered Mowers)
Locate the Gas Tank: Most gas-powered lawn mowers have a gas tank located at the rear or side of the engine.
Check the Fuel Level: Unscrew the gas cap and check the fuel level. If it’s low, add the recommended fuel type (usually unleaded gasoline with a minimum of 87 octane).
Avoid Overfilling: Ensure the fuel level is below the filler neck to prevent spillage.
2. Check the Oil Level (Gas-Powered Mowers)
Locate the Dipstick: This is usually near the base of the engine, often marked with an oil symbol.
Check Oil Level: Remove the dipstick, wipe it clean with a cloth, reinsert it fully, and then pull it out again to check the oil level. The oil should be between the “full” and “add” marks.
Add Oil if Necessary: If the oil level is low, add the recommended type of oil slowly, checking frequently to avoid overfilling.
3. Inspect the Air Filter
Locate the Air Filter Cover: This is usually on the side of the engine.
Check the Filter: Open the cover and inspect the air filter. If it’s dirty or clogged, replace it with a new one or clean it if it’s reusable.
Secure the Cover: Ensure the air filter cover is securely fastened after inspection.
4. Check the Spark Plug (Gas-Powered Mowers)
Locate the Spark Plug: It’s usually on the front or side of the engine.
Inspect the Spark Plug Wire: Ensure that the spark plug wire is firmly connected. If it’s loose, push it back onto the spark plug.
5. Battery Check (Electric Mowers)
Corded Electric Mowers: Ensure the extension cord is properly connected to a power outlet.
Cordless Electric Mowers: Make sure the battery is fully charged and securely attached to the mower.
6. Clear the Mowing Area
- Remove Obstacles: Before starting your mower, clear the lawn of any debris, such as sticks, rocks, or toys, which could damage the mower or cause injury.
- Inspect the Mower Blade: Tilt the mower carefully (refer to the manual to avoid oil or fuel spillage) and check the blade for sharpness and damage. A dull or damaged blade should be sharpened or replaced.
Starting a Gas-Powered Lawn Mower
Starting a gas-powered lawn mower typically involves either a pull-cord start or an electric start button. Here’s how to do both:
1. Starting with a Pull Cord
Step 1: Prime the Engine: Locate the primer bulb, usually a small rubber button on the engine. Press it 3-5 times to draw fuel into the carburetor. This step is essential for cold starts.
Step 2: Set the Throttle: Move the throttle lever to the “fast” or “choke” position. This position provides the engine with a richer fuel mixture for easier starting.
Step 3: Engage the Safety Lever: Most mowers have a safety lever on the handle that must be held down while starting the mower. Hold it firmly against the handle.
Step 4: Pull the Cord: Stand behind the mower, brace yourself, and pull the starter cord sharply. You may need to pull the cord several times before the engine starts, especially if it’s a cold start.
2. Starting with an Electric Start
Step 1: Prime the Engine: Press the primer bulb 3-5 times if your mower requires it.
Step 2: Set the Throttle: Move the throttle to the “fast” or “choke” position.
Step 3: Engage the Safety Lever: Hold down the safety lever on the handle.
Step 4: Press the Start Button: Simply press the start button. The mower should start immediately. If it doesn’t, you may need to check the battery or connection.
Starting an Electric Lawn Mower
Electric lawn mowers are generally easier to start than gas-powered ones, as they don’t require fuel or oil checks. However, you still need to take a few preparatory steps.
1. Corded Electric Mowers
Step 1: Plug In: Plug the mower’s power cord into an outdoor-rated extension cord and then into a grounded power outlet.
Step 2: Engage the Safety Lever: Hold down the safety lever, usually located on the handle.
Step 3: Press the Start Button: Press and hold the start button. The mower should start immediately. Release the start button while holding the safety lever to keep the mower running.
2. Cordless Electric Mowers
Step 1: Insert the Battery: Ensure the battery is fully charged, then insert it into the designated slot on the mower.
Step 2: Engage the Safety Lever: Hold down the safety lever on the handle.
Step 3: Press the Start Button: Press and hold the start button. The mower should start immediately, and you can release the start button while continuing to hold the safety lever.
Common Troubleshooting Tips
Even with the best preparation, you might encounter some issues when starting your lawn mower. Here are some common problems and their solutions:
1. Engine Won’t Start (Gas Mowers)
Check Fuel: Ensure there’s enough fuel in the tank. Old or stale fuel can cause starting issues. If necessary, drain the old fuel and refill with fresh fuel.
Check the Spark Plug: If the spark plug is dirty or damaged, clean or replace it.
Check the Air Filter: A clogged air filter can prevent the engine from starting. Replace it if it’s dirty.
2. Engine Stalls or Runs Rough (Gas Mowers)
Check the Carburetor: A dirty or clogged carburetor can cause the engine to run poorly. Consider using a carburetor cleaner or take it to a professional for servicing.
Check the Fuel Line: Ensure the fuel line is not blocked or leaking.
3. Electric Mower Won’t Start
Check the Power Source (Corded): Ensure the extension cord is properly connected and that the outlet is functioning.
Check the Battery (Cordless): Make sure the battery is fully charged and securely connected to the mower.
Check Safety Features: Ensure that all safety switches and levers are engaged properly.
4. Mower Starts but Blades Won’t Engage
Check the Blade Control: Ensure the blade control lever is engaged.
Inspect the Drive Belt: If your mower has a drive belt, ensure it’s not broken or slipped off. Replace it if necessary.
Safety Tips
Starting and operating a lawn mower involves certain risks. To ensure your safety and the safety of those around you, keep these tips in mind:
Wear Appropriate Clothing: Always wear sturdy shoes (no sandals) and long pants to protect yourself from debris.
Use Hearing Protection: Gas-powered mowers can be loud, so consider using earplugs or earmuffs.
Never Refuel a Hot Engine: Allow the mower to cool down before refueling to avoid fire hazards.
Mow in Daylight: Ensure you have good visibility while mowing to avoid accidents.
