Troubleshooting
Wrench slips on fastener
Ensure the wrench is fully seated on the 17mm hex head. Verify that the fastener is not damaged or rounded. Use a torque wrench for controlled application of force.
Difficulty reaching fastener
Combine the sensor wrench with appropriate 1/2" drive extensions and universal joints for better maneuverability. Assess if the fastener location is accessible with any tool.
Wrench appears loose on drive tool
Check for debris or wear on both the wrench's drive socket and the mating end of your ratchet or extension. Ensure a secure connection.
