Types of Craftsman Weed Eaters

Craftsman manufactures three primary types of weed eaters, each with a unique startup process. Understanding which model you own is the first step to answering How Do You Start a Craftsman Weed Eater? correctly, as gas, corded electric, and cordless models require different pre-start steps and operating procedures.

Below is a comparison of the three most common Craftsman weed eater models to help you identify your unit and understand its key features:

If you’re still unsure which model you own, check the model number printed on the side of the weed eater’s motor housing or on the original packaging. Craftsman model numbers typically start with a letter followed by numbers, such as CMXGTAMD or CMEWA, which correspond to gas and electric models respectively.

Pre-Start Safety Checks

Before you even think about pulling the starter cord or flipping the power switch, completing a quick safety check will protect you from injury and prevent damage to your weed eater. These steps apply to all Craftsman weed eater models, regardless of power source:

1. Clear the work area: Remove rocks, sticks, toys, and other debris from the area you plan to trim. These objects can become dangerous projectiles when caught by the cutting line, and they can also damage the weed eater’s engine or motor.
2. Wear appropriate protective gear: Always wear safety glasses or goggles to protect your eyes from flying debris, closed-toe shoes to prevent foot injuries, and long pants to protect your legs from the cutting line and stray vegetation. If you’re using a gas-powered model, avoid loose clothing that could catch on the engine.
3. Inspect the cutting head: Make sure the cutting line is properly installed, not frayed or broken, and that the guard is securely attached. A damaged cutting head can break during use, causing serious injury.
4. Check for fuel or battery issues: For gas models, confirm there is no fuel leakage around the tank or fuel lines. For electric models, inspect the power cord for fraying or exposed wiring, and for cordless models, make sure the battery is free of cracks or damage. For gas-powered models, also check the oil level if your engine has a separate oil reservoir. Low oil can cause the engine to seize during startup, leading to permanent damage.
5. Engage the safety lock (if equipped): Most Craftsman weed eaters have a safety lock or trigger lock that prevents accidental startup. Confirm it is engaged before you begin the startup process to avoid unexpected activation.

Skipping these safety checks can lead to preventable accidents, so take 30 seconds to complete them every time you use your tool.

Starting a Gas-Powered Craftsman Weed Eater

Gas-powered Craftsman weed eaters are the most popular choice for users with large yards or thick vegetation, but they require a specific startup process to avoid flooding the engine or causing unnecessary wear. The process changes slightly depending on whether your engine is cold (has not run for at least an hour) or warm (has been running recently).

Cold Start Procedure for Gas Models

Follow these steps to start a cold gas-powered Craftsman weed eater:

1. Place the weed eater on a flat, stable surface. Make sure the cutting head is clear of any grass or debris, and the safety lock is engaged.
2. Locate the fuel shutoff valve (usually on the side of the fuel tank or near the carburetor) and turn it to the “On” position if your model is equipped with one. This allows fuel to flow to the engine.
3. Press the primer bulb (a small rubber bulb near the carburetor) 3 to 5 times. You should see fuel begin to fill the bulb after 3 or 4 presses. Priming pushes fuel into the carburetor to help the engine start, but avoid pressing it more than 5 times, as over-priming will flood the engine. If your Craftsman gas weed eater does not have a primer bulb, you may need to pull the starter cord 5 to 7 times to draw fuel into the carburetor before it will start. Check your owner’s manual to confirm if your model is equipped with a primer bulb.
4. Set the choke lever to the “Full” or “Cold Start” position. The choke restricts air flow to the carburetor to create a richer fuel mixture for cold engines.
5. Move the throttle trigger to the “Fast Start” or “Start” position, usually marked with a rabbit icon or the word “Start.”
6. Pull the starter cord slowly until you feel resistance, then pull firmly and quickly 2 to 3 times. Do not pull the cord all the way out, as this can damage the recoil mechanism.
7. Once the engine starts, let it run for 30 seconds with the choke still engaged. Then gradually move the choke lever to the “Off” or “Run” position. If the engine stalls when you turn off the choke, let it run a bit longer with the choke on before switching it off completely.
8. Release the safety lock and squeeze the throttle trigger to test the cutting head. Your weed eater is now ready to use.

Warm Start Procedure for Gas Models

If your Craftsman weed eater has been running within the last hour, you can skip most of the cold start steps to avoid flooding the engine:

1. Place the weed eater on a flat surface and confirm the cutting head is clear.
2. Turn the fuel shutoff valve to the “On” position if equipped.
3. Set the choke lever to the “Half” or “Off” position. A warm engine does not need the extra fuel mixture provided by the full choke setting.
4. Pull the starter cord firmly 1 to 2 times. The engine should start immediately.
5. If the engine does not start after two pulls, switch the choke to the “Full” position for one more pull, then return it to half or off once the engine is running.

Warm starting your weed eater reduces wear on the starter cord and prevents fuel waste from over-priming.

Starting an Electric Craftsman Weed Eater

Electric Craftsman weed eaters are far simpler to start than gas models, as they do not require priming, choke adjustment, or fuel mixing. The startup process varies slightly between corded and cordless models, but both take only a few seconds to get running.

Starting a Corded Electric Craftsman Weed Eater

Corded electric Craftsman weed eaters are tethered to a power outlet, so they have unlimited runtime as long as you have access to electricity. Follow these steps to start one:

1. Plug the weed eater’s power cord into an outdoor-rated, grounded extension cord. Make sure the extension cord is rated for outdoor use and is at least 12-gauge to avoid voltage drops that can damage the motor. Make sure the extension cord is long enough to reach your work area without being stretched tight, as a taut cord can become damaged or disconnected during use. Avoid running the cord over sharp edges or through puddles, as this can create an electrocution hazard.
2. Confirm the extension cord is not frayed, cut, or exposed to water. Never use a damaged cord, as this creates an electrocution risk.
3. Engage the safety lock on the handle to prevent accidental startup.
4. Press the power trigger or switch to turn on the motor. Some models require you to squeeze the trigger while pressing a separate power button; check your owner’s manual for model-specific instructions.
5. Release the safety lock once the motor is running, and squeeze the throttle trigger to adjust the cutting line speed as needed.

Starting a Cordless (Battery-Powered) Craftsman Weed Eater

Cordless Craftsman weed eaters run on rechargeable lithium-ion batteries, offering cord-free convenience for users without easy access to outdoor outlets. To start a cordless model:

1. Confirm the battery is fully charged. Most Craftsman batteries have an LED indicator light that shows the charge level; a solid green light means the battery is fully charged, while a red or flashing light means it needs to be recharged.
2. Align the battery with the port on the bottom of the weed eater handle and slide it in until you hear a click. This confirms the battery is securely locked in place.
3. Engage the safety lock on the handle.
4. Press the power trigger or switch to turn on the motor. Some models require you to hold the safety lock while squeezing the trigger to start; refer to your owner’s manual for specific instructions for your model.
5. Release the safety lock once the motor is running, and adjust the throttle as needed for your trimming task.

One of the biggest benefits of cordless Craftsman weed eaters is their instant startup with no priming or warm-up time required.

Troubleshooting Common Startup Issues

Even if you follow the correct startup steps, you may occasionally run into issues that prevent your Craftsman weed eater from starting. Below are the most common problems and their solutions:

Weed Eater Won’t Start After Priming

If you’ve primed the bulb and pulled the starter cord multiple times with no luck, the issue is likely one of the following:

• Old or stale fuel: Gasoline goes bad after 30 days, especially if it contains ethanol. Drain the old fuel from the tank and replace it with fresh, ethanol-free gas for best results.
• Clogged spark plug: A dirty or worn spark plug will not create the spark needed to ignite the fuel. Remove the spark plug, clean it with a wire brush, or replace it if it is damaged.
• Dirty air filter: A clogged air filter restricts air flow to the engine, making it impossible to start. Remove the air filter cover, clean the filter with soap and water (if reusable) or replace it if it is disposable.
• Clogged fuel line: Old fuel can leave gummy residue in the fuel line, blocking fuel flow to the carburetor. Clear the line with a small wire or replace it if it is severely clogged.

Engine Sputters Then Dies After Starting

If your gas-powered Craftsman weed eater starts but sputters and dies within a few seconds, try these fixes:

• Turn off the choke gradually: If you left the choke on full after starting, the engine is getting too much fuel and not enough air. Slowly move the choke to the “Off” position as the engine warms up.
• Check the fuel mixture: If you mixed your own fuel, confirm you used the correct ratio of gas to oil (usually 50:1 for most Craftsman models). Using too much oil will cause the engine to run poorly and die.
• Clean the spark arrestor: The spark arrestor (a small screen in the muffler) can get clogged with carbon buildup over time, restricting exhaust flow. Remove and clean it with a wire brush to restore proper airflow. If cleaning the spark arrestor and adjusting the choke does not fix the sputtering issue, the carburetor may need to be adjusted or cleaned. Consult your owner’s manual for carburetor adjustment instructions, or take the weed eater to a small engine repair shop for professional service.

Electric Model Won’t Power On

If your corded or cordless Craftsman weed eater won’t turn on, check these common issues first:

• Dead battery (cordless models): Charge the battery fully before use. If the battery no longer holds a charge, it may need to be replaced.
• Damaged power cord (corded models): Inspect the entire length of the cord for fraying, cuts, or exposed wiring. Never use a damaged cord; replace it immediately to avoid electrocution risk.
• Tripped circuit breaker: If you’re using a corded model, check the circuit breaker for the outlet you’re using. Reset it if it has tripped, and avoid plugging multiple high-wattage tools into the same circuit.
• Safety lock still engaged: Most electric models will not turn on if the safety lock is activated. Make sure you release the lock fully before pressing the power switch.

If you’ve tried all these troubleshooting steps and your weed eater still won’t start, consult your owner’s manual or contact Craftsman customer support for further assistance.

Maintenance Tips to Ensure Smooth Startups

Regular maintenance is the best way to avoid startup issues and extend the life of your Craftsman weed eater. Follow these tips to keep your tool running reliably:

• Use fresh fuel for gas models: Always use fresh, ethanol-free gasoline with a minimum octane rating of 87. If you must use gas with ethanol, limit it to 10% or less, and add a fuel stabilizer if you plan to store the weed eater for more than 30 days.
• Clean the air filter after every 5 hours of use: A dirty air filter is one of the most common causes of poor performance and startup issues. Remove the filter, tap out loose debris, and wash it with soap and water if it is reusable. Replace disposable filters as recommended in your owner’s manual.
• Sharpen the cutting line regularly: A dull cutting line puts extra strain on the engine or motor, making it harder to start and reducing cutting performance. Replace the line when it becomes frayed or worn, and sharpen the blade on models that use a metal cutting blade.
• Store your weed eater properly: At the end of the season, drain all fuel from gas-powered models to prevent it from going stale and clogging the carburetor. Store all models in a dry, cool place away from direct sunlight and moisture.
• Inspect the spark plug every 25 hours of use: Clean or replace the spark plug as needed to ensure consistent spark for ignition. For gas-powered models, change the engine oil after every 25 hours of use or at the start of each mowing season, whichever comes first. Use the oil type recommended in your owner’s manual, typically 10W-30 for most Craftsman models.
• Keep the cutting head clean: Remove grass and weed buildup from the cutting head after each use to prevent it from jamming and putting extra strain on the motor or engine.

Following these simple maintenance steps will reduce the number of startup issues you encounter and keep your Craftsman weed eater running like new for years.

Common Mistakes to Avoid When Starting Your Craftsman Weed Eater

Many users accidentally create startup issues by making simple, avoidable mistakes. Avoid these common errors to make starting your Craftsman weed eater as easy as possible:

• Over-priming the carburetor: Pressing the primer bulb more than 5 times will flood the engine with fuel, making it impossible to start until the excess fuel drains. Stick to 3 to 5 presses for cold starts, and skip priming entirely for warm starts.
• Using the wrong fuel type: Never use diesel, E85, or gas with more than 10% ethanol in your Craftsman gas-powered weed eater. These fuels can damage the carburetor and engine, leading to permanent startup issues.
• Skipping the safety area check: Starting your weed eater without clearing debris from the work area can cause serious injury from flying projectiles, and can also damage the cutting head if it hits a rock or stick during startup.
• Pulling the starter cord too hard or too far: Yanking the starter cord all the way out or pulling it too forcefully can break the recoil spring, making it impossible to start the weed eater until the spring is replaced. Pull the cord firmly but smoothly, and stop once you feel resistance.
• Storing the weed eater with fuel in the tank: Stale fuel is the leading cause of gas-powered weed eater startup issues. Always drain the fuel tank before storing the tool for more than 30 days, or add a fuel stabilizer to keep the fuel fresh.
• Using indoor extension cords for electric models: Indoor extension cords are not rated for outdoor use and can overheat, causing a fire hazard or damaging the weed eater’s motor. Always use an outdoor-rated, grounded extension cord with the correct gauge for your model. Another common mistake is starting the weed eater with the cutting head touching the ground. This can cause the engine to stall immediately, and can also damage the cutting line or the cutting head guard. Always lift the cutting head a few inches off the ground before starting the tool.

Avoiding these mistakes will save you time, frustration, and money on repairs down the line.

Frequently Asked Questions

How Do You Start a Craftsman Weed Eater That Has Been Sitting for Months?

If your Craftsman weed eater has been stored for several months, start by addressing stale fuel and clogged components first. For gas-powered models, drain all old fuel from the tank, clean or replace the spark plug, replace the air filter, and then follow the cold start procedure outlined earlier in this guide. For electric models, fully charge the battery (cordless) or inspect the power cord for damage (corded) before following the standard startup steps. If the weed eater still won’t start after these steps, the carburetor may be clogged with old fuel residue, and you may need to clean or replace it. If the weed eater still fails to start after these steps, the carburetor may be severely clogged with old fuel residue, requiring a deep cleaning or replacement. You can clean a clogged carburetor yourself with a carburetor cleaning spray, or take the tool to a qualified small engine repair technician for service.

Can I Use Regular Unleaded Gas in My Craftsman Weed Eater?

Yes, you can use regular unleaded gasoline with an octane rating of 87 or higher in your Craftsman gas-powered weed eater. Avoid gas with more than 10% ethanol, as high-ethanol fuels can damage the carburetor and cause startup issues. For best performance and to prevent fuel system clogs, use ethanol-free gasoline whenever possible, and add a fuel stabilizer if you plan to store the weed eater for more than 30 days.

Why Does My Craftsman Weed Eater Flood When I Try to Start It?

Engine flooding is almost always caused by over-priming the carburetor or leaving the choke in the full position for too long after starting. If you prime the bulb more than 5 times, excess fuel enters the carburetor and prevents the engine from igniting. Similarly, leaving the choke on full after the engine has started will continue to feed excess fuel into the engine, causing it to flood. To fix a flooded engine, let the weed eater sit for 10 to 15 minutes to allow the excess fuel to drain, then follow the warm start procedure (skip priming, set choke to half or off) to restart it.

Do I Need to Prime the Bulb Every Time I Start My Weed Eater?

No, you only need to prime the primer bulb for cold starts, when the engine has been off for at least an hour and is at room temperature. Priming is not required for warm starts, and doing so will likely flood the engine. For warm starts, skip the priming step entirely and follow the warm start procedure outlined earlier in this guide.
