Tools & Materials
Kinked cord? You probably need a new cord guard. The power cord passes through the cord guard as it goes into the saw's handle. The cord guard gives extra support to the cord, preventing it from kinking and rubbing against the handle. The cord guard is made of rubber, which will eventually harden and crack. Once it does, the cord may kink or crack near the handle. This can lead to broken wires. Left unprotected, the cord can also rub against the handle housings, eventually rubbing through the insulation (leaving bare wires).
Let's get started.
REMOVING THE CORD GUARD 1. Remove half of the pistol grip handle.
a. Remove the four (smaller) screws securing the two halves of the pistol grip handle.

a. Remove the two screws securing the cord clamp to the handle.
b. Remove the cord clamp from the saw.
3. Remove the power cord.
