Introduction

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.

Tools

Parts

Ryobi p517 Circuit Board Assembly

Step 1

Lay the saw flat so the left side is facing up.
Remove the grey orbital button by twisting it counterclockwise.

Step 2

Remove the rubber boot from the device by peeling it from back to front.

Step 3

Flip the saw so its right side is facing up.
Remove the 10 mm screw using a Torx T27H screwdriver.

Step 4

Grab the black shoe assembly and pull it out from the front of the saw.

Step 5

Remove the two 12.5 mm screws from the front of the guide plate using the Torx T10H screwdriver.
Then remove the guide plate.

Step 6

Flip the saw so its right side is facing up.
Use the Torx T15H screwdriver to remove the eleven 18.1 mm screws from the housing assembly.

Step 7

Refer to the diagram provided to identify the gear case.
Use a Torx T15H screwdriver to remove the four 30.7 mm screws that are holding the housing assembly with the gear case assembly and gear case cover.

Step 8

Pull apart the two sides of the housing.
If the housing assembly does not come apart easily, do not try to force the pieces apart or else you may damage it. Ensure that all screws have been removed.

Step 9

Refer to the diagram on the device page to locate the trigger-switch, circuit board, and contact plate assembly. Each of these parts is connected by wires.
Remove the switch, circuit board, and contact plate holder assembly from the housing assembly.
Gently remove the switch by taking out the wiring from the assembly. Rough handling of the wiring could damage it and require it to be replaced.

Step 10

Lift and remove the gear case from the housing assembly and ensure that there are no parts remaining in housing assembly.
Ensuring the motor remains attached to the gear case to ease reassembly.

Step 11

Position the saw so the ports connecting the circuit board assembly to the motor are accessible.

Step 12

Use the soldering iron and desoldering pump to desolder the circuit board assembly from the motor.
Be extremely careful with soldering iron. Improper use of the iron could damage the device and could lead to bodily harm.
