Understanding Your Bolens Weed Eater

Bolens offers three primary types of weed eaters, each with unique start requirements and use cases. Knowing which type you own is the first step to mastering how to start a Bolens weed eater correctly, as the procedure for a gas-powered model will be completely different from a cordless electric version.

Below is a comparison of the three most common Bolens weed eater models to help you identify your tool and understand its unique features:

Beyond power source, all Bolens weed eaters share a few core components that you’ll interact with during the start process. The primer bulb (on gas models) pumps fuel into the carburetor to help with cold starts. The choke lever controls air flow to the engine, creating a richer fuel mixture for starting. The throttle trigger controls engine speed, and most models have a safety lock to prevent accidental starts. Gas models also have a fuel tank and spark plug, while electric models have a power switch or cord, and cordless models have a removable battery compartment. The throttle trigger is usually spring-loaded, and you must squeeze it firmly to engage the cutting line. Most models also have a lock-off button that you must press before squeezing the throttle to prevent accidental starts.

Common Bolens Models and Their Start Mechanisms

Some of the most popular Bolens weed eater models include the Bolens BL-110, a 25cc gas-powered trimmer with a pull-start mechanism and 50:1 fuel mix requirement. The Bolens EL-15 is a 15-inch corded electric trimmer with a push-button start and no fuel requirements. The Bolens BL-20V is a 20V cordless lithium-ion trimmer with a battery-powered start and variable speed control. Each of these models has slightly different start steps, which we’ll cover in detail later in this guide.

Key Components You Need to Know

Before attempting to start your weed eater, familiarize yourself with its key parts to avoid confusion during the start process. The starter cord handle (on gas models) is the ribbed grip you pull to crank the engine. The choke lever is usually located on the side of the carburetor, with positions marked “Start,” “Run,” and “Close.” The primer bulb is a small rubber bulb near the carburetor that you press to pump fuel. For electric and cordless models, the safety trigger lock is a small button on the handle that you must press while squeezing the main throttle to start the motor. Knowing where these parts are located will make the start process much faster and less frustrating.

Pre-Start Safety Checks

Skipping pre-start safety checks is one of the most common causes of injury and tool damage when operating a weed eater. Taking 2-3 minutes to complete these checks before every use will keep you safe and ensure your tool starts reliably.

Personal Protective Equipment (PPE)

Always wear the following protective gear before starting your Bolens weed eater:

• Safety glasses or a face shield: To protect your eyes from flying debris, rocks, and twigs thrown by the cutting line.
• Hearing protection: Gas-powered weed eaters can produce noise levels up to 100 decibels, which can cause permanent hearing damage over time. Ear plugs or over-ear muffs are recommended for all model types.
• Sturdy closed-toe boots: To protect your feet from the cutting line and sharp debris. Avoid sandals or open-toed shoes when operating a weed eater.
• Long pants and gloves: To protect your legs and hands from scratches, cuts, and blisters. Avoid loose clothing that could get caught in the cutting line.

Workspace Preparation

Before starting your tool, clear the area you’ll be working in of large rocks, sticks, toys, and other debris that could be thrown by the cutting line. Make sure no children, pets, or bystanders are within 50 feet of the work area, as flying debris can cause serious injury. If you’re working near a garden bed or lawn edge, mark any underground irrigation lines, electrical wires, or utility lines to avoid damaging them while trimming. For dusty areas, lightly wet down the ground with a hose to reduce airborne dust and debris while you work. If you’re working near trees, eaves, or overhead wires, make sure the cutting line will not come into contact with them during operation, as this can damage the line or cause the tool to kick back.

Weed Eater Inspection

Do a quick visual check of your weed eater before each use to catch potential issues early. For gas models, check the fuel tank for leaks, and make sure the fuel cap is tightened securely. For electric models, inspect the power cord for fraying or exposed wires, and make sure the cord is rated for outdoor use. For cordless models, check that the battery contacts are clean and free of debris, and that the battery is fully charged. Also, check the cutting line or blade for wear, and make sure the line head is tightened securely to avoid it coming loose during operation.

Fuel Preparation for Gas Models

Gas-powered Bolens weed eaters use 2-cycle (2-stroke) engines, which require a specific mix of gasoline and engine oil to run properly. Using the wrong fuel mix is one of the most common causes of start issues and engine damage, so this step is critical for gas model owners.

Correct Fuel Mix Ratio

Nearly all modern Bolens gas weed eaters require a 50:1 fuel mix ratio, meaning 50 parts unleaded gasoline to 1 part 2-cycle engine oil. For example, to make 1 gallon of fuel mix, add 2.6 ounces of 2-cycle oil to 1 gallon of 87 octane unleaded gasoline. Some older Bolens models (made before 2010) may require a 40:1 mix, so always check your owner’s manual for the exact ratio for your specific model. Use only gasoline with an octane rating of 87 or higher, and avoid ethanol-blended gas if possible, as ethanol can break down rubber seals and clog the carburetor over time. If you can only find ethanol-blended gas, use a fuel stabilizer to extend its shelf life and reduce damage to the engine. When mixing fuel, always mix it in a clean, approved fuel container, never directly in the weed eater’s fuel tank. This ensures the oil and gas are fully mixed before adding it to the tank, and reduces the risk of spills.

Fresh Fuel vs. Stale Fuel

Gasoline goes stale after 30 days of storage, especially ethanol-blended gas, which absorbs moisture from the air and forms varnish that clogs the carburetor and fuel lines. Using stale fuel is one of the top reasons gas-powered Bolens weed eaters fail to start after being stored for the winter or a few weeks. Always mix fresh fuel right before use, or add a fuel stabilizer to your mix if you plan to store the weed eater for more than a month. If you’re unsure how old your fuel is, it’s always better to drain it and mix a fresh batch – stale fuel can cause hundreds of dollars in carburetor damage if left unaddressed. Never store a gas-powered Bolens weed eater with fuel in the tank for more than 30 days, even with a fuel stabilizer, as stale fuel is the leading cause of carburetor damage and start issues in gas models.

Step-by-Step Guide to Starting a Bolens Weed Eater

Now that you’ve completed your safety checks and prepared your fuel (if applicable), you’re ready to start your Bolens weed eater. The exact steps vary slightly depending on whether you’re doing a cold start (first use of the day, or after long storage) or a warm start (after a short break), and whether you have a gas, electric, or cordless model. Below are the step-by-step procedures for each scenario.

Cold Start Procedure (First Start of the Day or After Long Storage)

Follow these steps for a cold start on a gas-powered Bolens weed eater:

1. Place the weed eater on flat, level ground. Ensure the cutting head is facing away from you, and there are no obstacles within 3 feet of the tool to avoid accidental contact with the line.
2. If your model has a primer bulb, press it 4 to 6 times slowly until you see fuel visible inside the bulb. This pumps fuel from the tank into the carburetor to help the engine start. Do not over-prime, as this can flood the engine with too much fuel. If your model does not have a primer bulb, you can skip this step – many newer Bolens gas models have an automatic primer system that engages when you pull the starter cord.
3. Move the choke lever to the “Start” or “Closed” position. This restricts air flow to the carburetor, creating a richer fuel mixture that ignites more easily in a cold engine.
4. Set the throttle trigger to the “Start” position, or hold the throttle trigger halfway down with one hand while pulling the starter cord with the other (check your owner’s manual for your model’s specific requirement).
5. Grip the starter cord handle firmly with your dominant hand. Pull the cord slowly at first until you feel resistance, then pull quickly and smoothly in a single motion. Do not yank the cord or let it snap back, as this can damage the starter mechanism.
6. After 2 to 4 pulls, the engine should sputter and start running. Once it starts, gradually move the choke lever to the “Run” or “Open” position over 10 to 15 seconds. If the engine dies, leave the choke in the closed position for another 1 to 2 pulls, then open it gradually again.
7. Let the engine idle for 30 seconds to warm up before engaging the throttle to full speed. This allows the engine oil to circulate properly and prevents damage to internal components.

For electric and cordless models, the cold start process is much simpler, and we’ll cover it in the next section. If you’re still having trouble with how to start a Bolens weed eater after trying these steps, consult your owner’s manual or contact Bolens customer support for assistance.

Warm Start Procedure (After Short Breaks)

If you’re starting your gas-powered Bolens weed eater after a 10 to 15 minute break, and the engine is still warm, follow these steps for a faster start:

1. Place the weed eater on flat ground, cutting head facing away from you.
2. Press the primer bulb 1 to 2 times only, if at all. A warm engine does not need as much fuel to start, so over-priming can cause flooding.
3. Leave the choke lever in the “Run” or “Open” position – a warm engine does not need a rich fuel mixture to start.
4. Pull the starter cord 1 to 2 times quickly and smoothly. The engine should start immediately.
5. Let the engine idle for 10 to 15 seconds before using full throttle to avoid putting unnecessary stress on the engine.

Starting Electric and Cordless Bolens Models

Electric and cordless Bolens weed eaters have far simpler start procedures than gas models, as they don’t require fuel mixing, priming, or choke adjustment. These models are ideal for beginners or for small yards where a gas model’s power is unnecessary.

Corded Electric Start Steps

1. Plug the weed eater’s power cord into a grounded 120V outdoor outlet. Make sure the cord is rated for outdoor use and is not frayed, cut, or exposed. Keep the cord away from the cutting line during operation to avoid cutting it.
2. Press the safety trigger lock (a small button on the side of the handle) with your thumb, then squeeze the main throttle trigger with your fingers.
3. The motor will start instantly – no pulling cords or priming required. Release the safety lock once the motor is running, and adjust the throttle pressure to control the cutting line speed.
4. When finished, turn off the motor, unplug the cord from the outlet, and wrap the cord loosely around the handle for storage.

Battery-Powered Cordless Start Steps

1. Check the battery’s charge level using the LED indicator on the battery pack. Most Bolens cordless weed eaters run for 30 to 60 minutes on a full charge, so charge the battery fully before use if the indicator shows low power.
2. Slide the battery into the compartment on the bottom of the weed eater handle until you hear a click, indicating it is locked in place.
3. Press the safety trigger lock with your thumb, then squeeze the throttle trigger with your fingers.
4. The motor will start instantly. Most Bolens cordless models have a variable speed trigger, so squeeze harder for faster cutting line speed, or lighter for slower trimming.
5. When finished, release the throttle to turn off the motor, then press the battery release button and slide the battery out for charging. Store the battery in a cool, dry place away from extreme temperatures to extend its lifespan.

Troubleshooting Common Start Issues

Even if you follow all the correct steps, you may occasionally run into start issues with your Bolens weed eater. Below are the most common problems and their fixes to get your tool running again quickly.

Engine Won’t Start After Multiple Pulls

If your gas-powered Bolens weed eater won’t start after 5 or more pulls, check the following:

• Empty fuel tank: Make sure you have fresh fuel mixed at the correct ratio in the tank. If the tank is empty, add fresh mix and try starting again.
• Clogged fuel line: Old, stale fuel can leave varnish in the fuel line, blocking fuel flow to the carburetor. Clear the line with a small wire or carburetor cleaner, or replace the line if it is severely clogged.
• Dirty spark plug: A fouled or worn spark plug will not ignite the fuel mixture. Remove the spark plug, clean it with a wire brush, or replace it with a new one (Bolens recommends part number 753-0818 for most models).
• Incorrect choke setting: Make sure the choke is closed for cold starts and open for warm starts. If the choke is in the wrong position, the engine will not get the right fuel mixture to start.
• Flooded engine: If you over-primed the engine or left the choke closed for too long after starting, excess fuel can flood the carburetor. Set the choke to open, pull the starter cord 3 to 4 times to clear the excess fuel, and wait 5 minutes before trying again.
• Dead starter battery (for electric-start gas models): Some gas-powered Bolens models have an electric starter instead of a pull cord. If the starter won’t crank, check that the starter battery is charged and replace it if needed.

Engine Starts but Dies Immediately

If your weed eater starts but dies as soon as you release the starter cord, the issue is usually related to the fuel mixture or air flow:

• Choke still closed: Gradually open the choke lever after the engine starts. If you leave it fully closed, the engine will not get enough air to stay running.
• Dirty air filter: A clogged air filter restricts air flow to the engine, causing it to die. Remove the air filter cover, clean the filter with soap and water, or replace it if it is severely dirty.
• Incorrect fuel mix ratio: If you used the wrong mix of gas and oil, the engine will not run properly. Drain the fuel tank and mix fresh fuel at the correct 50:1 ratio (or the ratio specified in your manual).
• Air leak in the carburetor: A damaged carburetor gasket can let excess air into the engine, leaning out the fuel mixture. Replace the gasket if you notice cracks or wear.

Excessive Smoke or Rough Idling

If your weed eater produces thick white or blue smoke, or idles roughly after starting, the issue is usually related to the fuel mix or spark plug:

• Too much oil in the fuel mix: Blue smoke is a sign of excess oil burning in the engine. Drain the fuel tank and mix fresh fuel at the correct ratio to fix this.
• Dirty spark plug: A fouled spark plug can cause rough idling and poor performance. Clean or replace the spark plug as needed.
• Clogged air filter: A dirty air filter restricts air flow, causing the engine to run rich and produce smoke. Clean or replace the air filter.
• Carburetor out of adjustment: If the carburetor’s idle screw is set too low, the engine will idle roughly. Adjust the idle screw clockwise to increase idle speed, following the instructions in your owner’s manual. If you are not comfortable adjusting the carburetor yourself, take the tool to an authorized Bolens service center for help.

Maintenance Tips to Keep Your Bolens Weed Eater Running

Regular maintenance is the best way to avoid start issues and extend the lifespan of your Bolens weed eater. Follow these simple tips to keep your tool running reliably:

• Change the spark plug every 6 months or 50 hours of use: A worn spark plug is one of the most common causes of hard starting and poor performance. Use only the spark plug type recommended in your owner’s manual for best results.
• Clean the air filter after every 5 hours of use: A clogged air filter reduces engine performance and makes starting harder. For foam filters, wash with soap and water and let dry completely before reinstalling. For paper filters, replace them when they look dirty.
• Drain fuel before long-term storage: If you won’t be using your gas-powered weed eater for more than 30 days, drain the fuel tank and run the engine until it stops to clear the carburetor. This prevents stale fuel from clogging the system.
• Sharpen or replace the cutting line regularly: A dull cutting line puts extra strain on the engine, making it harder to start and reducing cutting performance. When replacing the cutting line, use only the line size and type recommended in your owner’s manual. Using a line that is too thick can overload the engine, while a line that is too thin will break easily during use.
• Store in a dry, sheltered area: Keep your weed eater in a garage or shed away from rain, snow, and extreme temperatures. For cordless models, remove the battery before storage and charge it every 3 months to prevent battery degradation. Avoid leaving the battery on the charger for more than 24 hours after it is fully charged, as this can reduce the battery’s overall lifespan.
• Check the throttle linkage annually: Lubricate the throttle linkage with a small amount of silicone spray to ensure smooth operation, and replace it if you notice stiffness or wear.

Common Mistakes to Avoid When Starting

Many users accidentally damage their Bolens weed eaters or cause start issues by making simple, avoidable mistakes. Avoid these common errors to keep your tool running smoothly:

• Using stale or ethanol-heavy fuel: As mentioned earlier, ethanol-blended gas goes stale quickly and can damage the carburetor. Always use fresh fuel with a fuel stabilizer if storing for more than a month.
• Over-priming the engine: Pressing the primer bulb too many times will flood the carburetor with excess fuel, making starting impossible. Stick to 4-6 presses for cold starts, 1-2 for warm starts.
• Yanking the starter cord: Pulling the starter cord too hard or letting it snap back can break the starter mechanism. Pull the cord smoothly and steadily, and let it retract slowly after each pull.
• Skipping the warm-up period: Running the engine at full throttle immediately after starting can damage internal components, especially in cold weather. Always let the engine idle for 30 seconds (cold start) or 10 seconds (warm start) before full use.
• Starting on an uneven surface: Trying to start a gas-powered weed eater on a hill or uneven ground can cause fuel to spill into the carburetor, leading to flooding or start issues. Always start on flat, level ground.
• Using the wrong fuel mix ratio: Using too much or too little oil in the fuel mix can cause engine damage, fouling, or hard starting. Always measure the oil and gas carefully to get the correct ratio. Only use oil labeled for air-cooled 2-cycle engines, as oil for water-cooled or 4-cycle engines will not lubricate properly and can cause engine damage. Never add oil directly to the gas tank without mixing it first, as this can lead to an incorrect fuel ratio and engine issues.

Frequently Asked Questions

How Many Pulls Should It Take to Start a Bolens Weed Eater?

For a cold start on a gas-powered Bolens weed eater, it should take 2 to 5 pulls of the starter cord to get the engine running. If it takes more than 10 pulls, check for issues like stale fuel, a dirty spark plug, or an incorrect choke setting. Electric and cordless models will start on the first trigger pull if the battery is charged or the tool is plugged in properly.

Can I Use Regular Gas in My Bolens Weed Eater?

Yes, but only if it is unleaded 87 octane gasoline mixed with 2-cycle engine oil at the correct ratio (usually 50:1 for most models). Never use diesel, premium gas with more than 10% ethanol, or straight gasoline without oil for 2-cycle gas models, as this will cause severe engine damage. Check your owner’s manual to confirm if your model is 2-cycle or 4-cycle (4-cycle models use straight gas and have a separate oil reservoir).

Why Is My Bolens Weed Eater Flooding?

Flooding occurs when too much fuel enters the carburetor, usually from over-priming the primer bulb, leaving the choke closed for too long after the engine starts, or trying to start a warm engine with the choke in the closed position. To fix a flooded engine, set the choke to the open position, pull the starter cord 3 to 4 times to clear the excess fuel, and wait 5 minutes before attempting to start again.

Do I Need to Mix Oil with Gas for My Bolens Weed Eater?

Only if you own a 2-cycle gas-powered Bolens weed eater. All gas-powered Bolens trimmers use 2-cycle engines, which require oil to be mixed directly with the gasoline to lubricate internal parts. 4-cycle Bolens models (rare, usually larger commercial trimmers) use straight gasoline and have a separate oil reservoir that you fill separately. Check your owner’s manual to confirm your model’s engine type.

How Often Should I Replace the Spark Plug?

For most Bolens weed eaters, you should replace the spark plug every 6 months or after 50 hours of use, whichever comes first. A worn or fouled spark plug will cause hard starting, rough idling, and poor engine performance. Bolens recommends using part number 753-0818 spark plugs for most of its gas-powered trimmer models for optimal performance.

Conclusion

Starting a Bolens weed eater doesn’t have to be a frustrating, trial-and-error process. By following the correct steps for your specific model type, completing pre-start safety checks, using fresh fuel for gas-powered trimmers, and performing regular maintenance, you can get your tool running quickly and reliably every time you use it. Whether you’re tackling a small residential yard with a cordless model or clearing thick brush on a large property with a gas-powered trimmer, the steps outlined in this guide will help you avoid common start issues and keep your Bolens weed eater running at peak performance for years. Mastering how to start a Bolens weed eater is simple once you understand the unique requirements of your tool, and with a little practice, you’ll be able to start it in seconds without any hassle.
