You wired it incorrectly. If it didn't trip before, and now it does? recheck the way you wired it. Most power tools have a single throw double pole switch. It seems like you have wired Active to Neutral at the switch to cause an immediate power trip.

check for a small button in the connecting parts of the pole press it in and slip the parts
on reassembly make sure that that button lines up with a hole and clicks in

Remington Saws have ceased operations and, unless you like to make your own replacement parts, they are prone to failure. The gearbox is sealed and the motor brushes are not available anywhere. Look elsewhere!

The bracket which holds the saw to the pole is not fully holding trigger in energized position

Problem is most likely in the trigger switch on pole. Bypass switch and test bu plugging lamp into power cord coming from pole

I'm so confused. This is reported as a Poulan and McCulloch pole saw, which one? Is it a pole saw? That is the only 445 Poulan I can find. It is reported as an electric but has a fuel routing problem.

If it is a Poulan Pro gas pole saw it is here: PP445 Gas Pole Pruner
The fuel system routing is terrible, but it is all there is.
Fuel Routing follows:
Tank to carburetor (hose in tank with filter on free end)
Carburetor to primer (primer draws fuel from the tank through the carb)
Primer to fuel tank (returns any excess fuel to tank when pushed) HTH
