Porter-Cable PCC710B Troubleshooting

When the on/off switch is in the on position, the tool is not powering on even when the battery is fully charged.

Over time, dirt and debris can build up on the tool causing it to malfunction. To clean the tool: remove the battery and as many parts as you can. Then, use a soft cloth to wipe down the tool. Be sure to get into all of the nooks and crannies. Once the tool is clean, put all of the tool parts back on and try starting it again.

The switch controls the power to the motor. If the switch wears out or breaks, it will need to be replaced. You'll need to follow our guide for replacing a switch.

The motor is the power producer of the tool. A damaged motor can cause the oscillating tool not to turn on. To replace the motor take a look at this guide on how to replace the motor.

The tool does power on and the head does not oscillate (move back and forth) like it is supposed to.

Make sure that the blade is properly attached by following the steps below.

Step 1: Put the tool in an upright position so it is standing on the base where the battery goes.

Step 2: Align the blade and ensure the attachment you are putting on the tool is facing upwards (away from the tool) and not pointing downwards (towards the tool). The attachment itself should have a crosshair-like design, with the center space being surrounded by dashes in a circular pattern. When the dashes end and the circle space in the middle opens to a large slit, that slit is the opening that will slide downwards onto the tool.

Step 3: Pull back the trigger. You’ll need quite a bit of force; slide the attachment down onto the tool.

Step 4: Once you get the attachment into the created space by pulling on the trigger, turn the attachment left and right with your hand to ensure it is properly on the tool. You should hear a loud snap caused by the spring locking into place. The attachment should not be able to be twisted or turned from this final position and that is how you know the attachment is properly secured.

The shaft transmits power from the motor to the cutting blade. A worn or broken shaft will not be able to transmit power from the motor to the cutting blade. To access the eccentric shaft follow this guide.

When attempting to secure a blade to the multitool, the blade is loose or won’t attach properly.

The lever assembly is a gray clamp that holds blades and other attachments to the oscillating multi-tool. If the blades of your oscillating multi-tool are not staying firmly attached to the tool, it might be due to a faulty lever assembly. If the Lever Assembly breaks completely, you will not be able to attach or detach any blades or accessories. In this case, you'll need to replace it using this guide.

The spindle assembly helps hold the blades and attachments of the tool in place. If the power and motor are working properly and the attachments will not stay in place, it could be due to a malfunctioning spindle assembly. You'll need to follow this guide to replace it.

When the tool is powered on, it makes grinding and squealing sounds accompanied by an unnatural vibration of the tool.

A bearing is a device used to enable rotational or linear movement. It reduces friction and handles stress at the same time. Bearings are wear-and-tear items that need to be replaced over time. When a bearing wears out, it will produce a grinding, growling, or rumbling sound accompanied by a vibration. To check the condition of the bearing, you will need to access them using this guide.

The spindle assembly also rotates and is the key to the tool's ability to oscillate back and forth. If the power and motor are working properly but the Spindle is stuck or not moving properly, it could be due to a broken spindle assembly. You'll need to follow this guide to replace it.
