How to Disassemble a Makita 18V Cordless Drill

The Makita 18-volt cordless drill is an essential everyday power tool for many carpenters and tradesmen. But after using your drill for long periods of time, it can accumulate a lot of sawdust and general debris from everyday wear and tear. This build up can cause the drill to stop working properly. Whether you're cleaning or repairing your cordless drill, chances are that you'll have to dismantle it to some extent.

Locate the drill's battery pack attached to its handle. Press on the release buttons on each side of the drill, and remove the battery pack from the drill.

Lay the drill on its right side with the back of the drill facing you. Remove all Phillips-head screws from the back of the drill. The drill's housing is separated into two pieces that split down the middle of the drill's assembly. Lift up on the housing facing upward, and remove it from the rest of the drill.

Pull the drill's trigger out of its slot inside the handle assembly. Locate the "field assembly" inside the drill. This is the bundles of copper wire attached to the drill's motor. Lift it out of the drill, and set it aside.

Loosen and remove the Phillips-head screw on the drill's chuck, which is the fastening device used to attach all drill bits and extensions to the drill. Rotate the chuck in the counterclockwise direction until it's open all the way. Use a sturdy flathead screwdriver to pry the chuck from the drill.

Warning

Dismantling your drill will void your manufacturer's warranty.
