Use this guide to remove and replace the trigger on your Ryobi P517 reciprocating saw.
The trigger is responsible for initiating the cutting action of the saw. When you press the trigger, it activates the motor of the saw, causing the blade to start reciprocating. The trigger ensures that the saw only operates when intentionally activated by the user, ensuring additional safety. The trigger assembly needs to be replaced when it is unresponsive or if its connection to the other components is compromised. A poorly installed trigger assembly can impact the movement/response of the blade and the user safety. The trigger is connected to the circuit board assembly, so the circuit board must be replaced to replace the trigger.
Before reading this guide, please review the Ryobi P517 Troubleshooting Guide to ensure that your issue cannot be resolved externally, without removing the trigger. Remove the housing assembly before beginning the trigger removal process.
