Starting a gas string trimmer is a simple process that can be done in a few easy steps. First, make sure you have the necessary equipment, including safety goggles, gloves, and ear protection. Next, check the fuel and oil levels and fill them if needed. Then, prime the engine by pressing the primer bulb several times. After that, set the choke to the “Start” position and pull the starter cord firmly and quickly. Once the engine starts, let it warm up for a minute before adjusting the choke and throttle. Finally, you’re ready to start trimming! Remember to always follow the manufacturer’s instructions for your specific trimmer model.
To start a gas-powered string trimmer, follow these general steps: switch it on, close the choke, and pull the starting cord. However, it’s crucial to read the instructions provided by the manufacturer since trimmer designs can vary. If your trimmer has a priming bulb, press it multiple times before pulling the starting cord to ensure gas reaches the carburetor. The number of presses required can vary from four to ten, depending on the model. Avoid excessive priming to prevent engine flooding.
1. Stabilize the Trimmer
Place the trimmer flat on the ground or a workbench. This will allow you to hold it steady with one hand while pulling the cord with the other.
2. Check the Gas and Oil
Open the gas tank and ensure that the trimmer has enough gas.
3. Turn On the Power Switch
Locate the on/off switch, which can be on the motor housing or the trimmer shaft, and turn it on.
4. Close the Choke or Push the Priming Bulb
If your trimmer has a choke, move the small lever near the gas tank to the “on” or “choke” position. For models with a priming bulb, press it the specified number of times according to the manual.
5. Pull the Starting Cord
Hold the trimmer securely with one hand and pull the starting cord sharply with the other. Once the motor turns over and the trimmer starts, move the choke back to the “off” or “closed” position.
Preventing Engine Flooding
While the trimmer may not start on the first pull, repeated attempts usually do the trick. However, be cautious not to over-prime the engine, which can lead to flooding. If you smell gas after several attempts, wait 10 or 15 minutes to allow the gas to drain before trying again. If the trimmer still won’t start, there may be underlying issues that require further troubleshooting and maintenance.
Troubleshooting Tips
To troubleshoot starting issues, check the air filter first. A dirty filter can prevent air from entering the carburetor, so clean or replace it if necessary. Next, inspect the spark plug. Use a spark plug wrench to remove it and clean the contacts with sandpaper, or replace the plug altogether. If these solutions don’t work, a clogged carburetor or fuel line might be the problem. In this case, a simple hack can potentially solve the issue without disassembling the trimmer.
Remove the air filter and spray a one-second burst of engine starting fluid, available at car parts or hardware stores, into the carburetor through the air intake passageway. Without engaging the choke or priming button, immediately pull the starting cord. This should help clear any clogs in the carburetor. If the problem persists, it’s advisable to seek professional servicing or, if competent, clean the carburetor yourself.
