Starting a Craftsman push mower can be a straightforward process if you understand the proper steps and maintenance procedures. Whether you're a new owner or need a refresher, knowing how to properly start your mower ensures efficient operation and prolongs its lifespan. In this comprehensive guide, we will walk you through the essential steps, safety precautions, troubleshooting tips, and maintenance practices to get your craftsman push mower up and running smoothly.
Understanding Your Craftsman Push Mower
Types of Craftsman Mowers
Before diving into the starting procedure, it's important to know which type of Craftsman mower you own:
- Push Mowers: Traditional walk-behind models powered by a small gasoline engine.
- Self-Propelled Mowers: Mowers with a drive system that moves the mower forward with minimal effort.
- Battery-Powered Mowers: Electric models that run on rechargeable batteries.
- Riding Mowers: Larger models, typically not classified as push mowers but part of the Craftsman lineup.
This guide primarily focuses on gasoline-powered Craftsman push mowers, which are among the most common.
Key Components to Know
Familiarize yourself with the main parts involved in starting:
- Engine: Typically a four-stroke gasoline engine.
- Primer Bulb: Used to pre-heat the carburetor for easier starting.
- Recoil Starter: The pull cord used to start the engine.
- Throttle Control: Adjusts engine speed and can assist in starting.
- Choke: A valve that enriches the fuel mixture for cold starts.
- Fuel Tank: Contains the gasoline required for operation.
- Spark Plug: Ignites the fuel-air mixture inside the engine.
Understanding these parts helps in troubleshooting and executing the starting process effectively.
Preparing to Start Your Craftsman Push Mower
Safety Precautions
Before starting, prioritize safety:
- Wear sturdy shoes and protective gear.
- Clear the area of debris, rocks, or objects that could be thrown by the blades.
- Ensure the mower is on a flat, stable surface.
- Never start the mower indoors or in enclosed spaces to avoid carbon monoxide buildup.
- Always read the manufacturer's manual for specific instructions and safety warnings.
Inspect and Prepare the Mower
A quick pre-start check can prevent issues:
- Check the oil level; top up if necessary.
- Verify there is enough gasoline; fill the tank if empty.
- Inspect the blade for damage or obstructions.
- Ensure the air filter is clean.
- Confirm the safety features, such as the blade brake or operator presence control, are functioning properly.
- Make sure the spark plug wire is connected.
Prime the Engine
Most Craftsman push mowers have a primer bulb:
- Press the primer bulb 2-3 times to draw fuel into the carburetor.
- Do not over-prime, as this can flood the engine.
Set the Choke and Throttle
- Choke: Move the choke lever to the 'Start' or 'Closed' position for a cold start. This enriches the fuel mixture.
- Throttle: Set to the 'Fast' or 'Start' position, often marked on the control.
Starting Your Craftsman Push Mower
Step-by-Step Starting Procedure
Follow these steps to start your mower efficiently:
1. Ensure Safety Interlocks Are Engaged: Some models require the operator presence control handle to be engaged.
2. Engage the Brake or Safety Bar: Hold the safety bar or handle to prevent accidental starts.
3. Pull the Recoil Cord: Grip the handle firmly and pull smoothly and quickly. You may need to pull several times if the engine is cold.
4. Adjust the Choke: Once the engine fires (you'll hear it sputter or catch), move the choke to the 'Run' or 'Open' position.
5. Release the Safety Bar: If your mower has a safety bar, release it once the engine is running smoothly.
6. Set the Throttle to the Desired Speed: Increase the throttle to the 'Run' position for normal operation.
7. Begin Mowing: Engage the blades if necessary and start mowing.
Starting a Warm Engine
If the engine has been recently used:
- Set the choke to the 'Open' or 'Run' position.
- Pull the recoil cord; starting a warm engine usually requires fewer pulls.
- Adjust the throttle as needed once the engine starts.
Troubleshooting Common Starting Issues
Engine Won't Start
- Check Fuel Supply: Ensure there is fresh gasoline in the tank.
- Inspect Spark Plug: Remove and examine for fouling or damage; replace if necessary.
- Verify the Air Filter: A clogged filter can prevent starting; clean or replace.
- Prime the Engine Properly: Use the primer bulb as instructed.
- Ensure Safety Features Are Engaged: Some models won't start unless safety controls are active.
- Check the Carburetor: May need cleaning if fuel is stale or clogged.
Engine Fails to Keep Running
- Adjust the Choke: If the engine stalls after starting, the choke may need to be gradually opened.
- Inspect for Fuel Blockages: Check fuel lines and filter.
- Clean or Replace the Spark Plug: Fouled plugs can cause poor engine performance.
- Check Oil Level: Low oil can trigger safety shut-offs.
Maintaining Your Craftsman Push Mower for Easy Starts
Regular Maintenance Tips
- Change the Oil: Follow the manufacturer's schedule, typically after every 25-50 hours of use.
- Clean or Replace the Air Filter: Dirty filters hinder starting and performance.
- Inspect and Replace the Spark Plug: A clean, properly gapped spark plug ensures reliable ignition.
- Use Fresh Fuel: Avoid stale gasoline, which can cause starting issues.
- Check the Carburetor: Periodic cleaning prevents fuel flow problems.
- Sharpen the Blades: Dull blades can strain the engine during operation.
Seasonal Storage Tips
- Drain the fuel or add fuel stabilizer before storing.
- Store in a dry, sheltered location.
- Remove the spark plug and add a small amount of oil into the cylinder, then pull the recoil cord to distribute oil.
- Cover the mower to prevent dust and moisture accumulation.
Conclusion
Starting a Craftsman push mower correctly involves understanding the key components, preparing the mower safely, and following a systematic procedure. Always prioritize safety, perform regular maintenance, and troubleshoot common issues promptly to ensure your mower starts easily every time. With proper care and attention, your Craftsman push mower will serve you reliably season after season, making lawn care less of a chore and more of a pleasure.
Frequently Asked Questions
What are the initial steps to start a craftsman push mower for the first time?
Begin by ensuring the mower is on a flat surface, check the oil and fuel levels, set the throttle to the 'start' position, and ensure the safety lever is engaged before pulling the starter cord.
How do I prime a Craftsman push mower before starting?
Locate the carburetor primer bulb, usually near the air filter, and press it about 2-3 times until you see fuel fill the bulb. This helps to improve starting by supplying fuel directly to the engine.
What should I do if my Craftsman push mower doesn't start after pulling the cord?
Check the fuel tank for fuel, ensure the safety lever is engaged, verify the spark plug is clean and connected, and inspect the air filter for clogs. If issues persist, consider checking the spark plug or consulting a technician.
Is it necessary to choke the engine when starting a Craftsman push mower?
Yes, for cold starts, set the choke to the 'on' position to enrich the fuel mixture, which helps start the engine. Once the engine runs smoothly, gradually move the choke to the 'off' position.
How to troubleshoot starting problems with a Craftsman push mower?
Check for fuel supply, inspect the spark plug for damage or fouling, ensure the safety features are engaged, and verify the air filter isn't clogged. Regular maintenance can prevent many starting issues.
What safety precautions should I take before starting a Craftsman push mower?
Always wear closed-toe shoes, ensure the area is clear of debris and people, engage the safety lever, and make sure the mower is on a flat surface before starting to prevent accidents.
Can I start my Craftsman push mower without priming or choking?
It's generally not recommended; priming and choking help start the engine more easily, especially in cold conditions. Skipping these steps may result in difficulty starting or engine damage.
