4. Operating Instructions
The controller is an integral part of your Makita power tool, responsible for managing its electronic functions, such as motor speed, torque, and other operational parameters. Once correctly installed, the tool should operate as intended by the manufacturer. There are no direct user controls on the controller itself; its function is to enable the tool's normal operation via the tool's existing switches and controls.
5. Maintenance
As an internal electronic component, the controller requires minimal user maintenance. However, to ensure its longevity and proper function:
- Keep the power tool clean and free from dust, debris, and moisture. Excessive dust or moisture can affect electronic components.
- Avoid dropping or subjecting the tool to severe impacts, as this can damage internal circuitry.
- Periodically inspect the tool for any signs of loose connections or damaged wiring. If found, address them promptly or seek professional assistance.
- Store the tool in a dry, temperature-controlled environment.
6. Troubleshooting
If your Makita DTD172 or TD172D power tool is not functioning correctly after controller replacement, consider the following troubleshooting steps:
- Tool Not Powering On: Ensure the battery is fully charged and properly seated. Double-check all wiring connections to the controller for looseness or incorrect placement.
- Intermittent Operation: Inspect for any loose or corroded connections. Ensure no wires are pinched or frayed within the tool casing.
- Unusual Noises or Smells: Immediately discontinue use and disconnect the battery. This could indicate a serious electrical issue. Seek professional inspection.
- Tool Not Responding to Controls: Verify that the tool's switches and triggers are functioning correctly and that their connections to the controller are secure.
If problems persist after checking these points, it is recommended to consult a qualified power tool repair technician or contact Makita service for further assistance.
