Trimmer: Trigger Doesn't Work

If your trimmer trigger is not working, refer to our repair and symptom guide to help you better identify this problem. Check the following parts for damage: the housing, springs, trigger, and cable. Note: this is a general repair guide. Check the manual provided by your owner for more specific repair information related to your model.

Housings
Housings
The housing holds the throttle cable, spring, and trigger (also known as a lever). If anything inside the housing breaks, it can impact the function of the trigger. Remove the screws on the handle and separate the two halves of the handle. Look for any parts that are out of place that could indicate damage inside the handle. Inspect the mounting pin for the trigger as well as where the spring mounts, for any damage that could impact these parts from working properly. If there is damage, replace the handle. Remove the cable, trigger, and spring from the handle. Make note of the orientation of the spring. Take a photo with your phone so you can have it for a reference if needed. Install the throttle cable back into the trigger, then install the spring and reposition the trigger on the mounting pin. Make sure the throttle cable is seated...

Triggers
Triggers
The trigger controls the engine’s RPMs. If the trigger is not working, it may have broken off inside the housing. The trigger is made of plastic and can break over time. To check and repair, simply remove the screws on the handle that house the trigger. Separate the two halves of the handle. Inspect the trigger for any breakage. Make note of the orientation of the spring; we suggest you take a picture with your phone to use as a reference. Remove the spring and the throttle cable from the trigger. With the new trigger, install the throttle cable first, then re-install the spring and reposition the trigger on the mounting pin. Make sure the throttle cable is seated properly inside the handle and rejoin the two halves of the handle back together.

Cable
Cable
The cable runs from the trigger to the throttle control on the carburetor. When you pull the trigger, the cable opens the throttle valve inside the carburetor, allowing more fuel into the engine. This increases the RPM. Over time, this cable can stretch, fray, or break, causing trigger failure. Separate the two halves of the handle. Make note of the orientation of the spring, and remove the spring and throttle cable from the trigger. Remove the cable from the handle. Remove the cover from the engine that will allow you to access the carburetor to remove the cable. Remove the screws securing the choke plate and carburetor to the engine. Maneuver the carburetor around to slide the cable out; if you cannot get the cable out with the carburetor, fasten down. Once the cable is detached from the carburetor, remove the cable from the trimmer and discard it. Install the...

Once the cable is detached from the carburetor, remove the cable from the trimmer and discard it. Install the new cable, hooking it back up to the carburetor. Fasten down the carburetor and choke plate. You should remove and install a new gasket under the carburetor for a proper seal at this point. Re-install any covers you removed to gain access to the carburetor. Install the throttle cable into the trigger, then re-install the spring and reposition the trigger on the mounting pin. Make sure the throttle cable is seated properly inside the handle and rejoin the two halves of the handle back together.
