Tools You’ll Need

Before you begin disassembling your Makita 6935FD, make sure you have the following tools and materials ready:

• Phillips and flathead screwdrivers
• Hex wrenches (if applicable)
• Needle-nose pliers
• A clean, well-lit workspace
• Lubricant or grease
• Compressed air for cleaning

Step-by-Step Guide to Disassemble the Makita 6935FD

Follow these steps carefully to disassemble your Makita 6935FD drill:

1. Prepare Your Workspace

Start by ensuring your drill is turned off and the battery pack is removed. Place the drill on a clean, flat surface and organize your tools nearby. It’s a good idea to take pictures at each step to reference later during reassembly.

2. Remove the Battery Pack

Slide the battery pack off the bottom of the drill by pressing the release buttons. This step ensures safety and eliminates the risk of accidental power activation.

3. Unscrew the Outer Casing

Use a Phillips screwdriver to remove the screws securing the outer casing of the drill. Keep the screws in a small container to avoid losing them. Once unscrewed, carefully separate the two halves of the casing.

4. Access the Internal Components

With the casing removed, you’ll see the internal components of the Makita 6935FD, including the motor, gearbox, trigger, and wiring. Inspect these components for visible wear or damage.

5. Remove the Chuck

To remove the chuck, insert a hex wrench into it and tighten it securely. Then, hold the drill firmly and strike the hex wrench with a mallet in the counterclockwise direction. This action will loosen the chuck from the spindle.

6. Disassemble the Motor and Gearbox

Disconnect the motor wires carefully, noting their positions for reassembly. Unscrew the gearbox assembly from the motor using the appropriate tool. Once separated, you can inspect and clean these components.

7. Clean and Inspect

Use compressed air to remove dust and debris from the internal parts. Check for worn gears, damaged wires, or any other issues. Apply a thin layer of lubricant to moving parts to ensure smooth operation.

8. Reassemble the Drill

Follow your disassembly steps in reverse order to reassemble the Makita 6935FD. Double-check that all screws are tightened and the wiring is correctly connected before replacing the casing and battery pack.

Troubleshooting Common Issues

While disassembling and inspecting your Makita 6935FD, you may encounter common issues. Here’s how to address them:

• Motor not running: Check for disconnected or damaged wires. Replace the motor if necessary.
• Gearbox issues: Inspect for worn or broken gears and replace as needed.
• Chuck won’t loosen: Apply penetrating oil and use additional force with the hex wrench.
• Trigger not responding: Test the switch with a multimeter and replace if faulty.

Precautions and Tips

To avoid damaging your drill or injuring yourself, follow these precautions:

• Always remove the battery pack before disassembling.
• Work in a well-lit and clean area.
• Keep small parts organized to prevent loss.
