Happy Repeat Customer
Finding the correct part was very easy. The part was delivered quicker than advertised, was in great shape and easy to install. Taking photos of the old, damaged part while removing it was helpful in installing the new part and assuring the wires were placed in the optimal locations.

Once the handle is off route the wires back through the square hole in the bottom of the handle.
Wire nut the white wire and route the two blacks on one side and the yellow and red on the other. Hook them back to the switch and reattach the black plastic switch with the round metal fastener. Put the top on and screw down the yellow handle then add the black top handle with the two larger screws.

The aluminum base broke causing the saw to separate from the collapsible stand it was mounted to. This allowed the clamshell switch handle to be broken making the chop saw unusable.

I removed all screws holding the chop saw to the aluminum base, and replaced the broken base with the new base purchased from your warehouse. I then removed all screws holding the clamshell handle and switch on the saw, and then in reverse order recounted the handle and switch. I then tested the saw with repairs complete and the saw worked like new.
