  If your Snapper Trimmer fails to start when the trigger lock is depressed, ensure the battery pack is correctly attached. If it is, try removing the battery and reinstalling it to ensure proper electrical contact. The battery may also be depleted and require charging. Finally, make sure you are pressing the lock-out button and trigger simultaneously; press down the lock-out button and hold it, then depress the trigger to turn on the string trimmer.

  If the line on your Snapper Trimmer keeps breaking, make sure you are only trimming with the tip of the line and avoiding contact with stones, walls, and other hard objects. Regularly feed the line to maintain the full cutting width.

Why won't the line advance on my Snapper ST48?

Alternatively, the lines may be tangled on the spool; remove the lines and rewind them.

  If your Snapper trimmer stops while cutting, several factors could be at play. Check if the guard is mounted, as its absence can cause the trimmer line to be too long, overloading the motor. Ensure you're using a nylon cutting line with a diameter of 0.080" or less. Grass binding the motor shaft or trimmer head can also cause this issue; if this occurs, stop the trimmer, remove the battery, and clear the grass. Overloaded motor may also cause the trimmer to stop; remove the trimmer head from the grass. The motor will recover to work as soon as the load is removed. When cutting, move the trimmer head in and out of the grass to be cut and remove no more than 8 inches of length in a single cut. Additionally, the battery pack or trimmer might be overheating, so allow them to cool. Ensure the b...
