New Dust Collector Trips GFI circuits
TLDR: Plug it into a different GFCI.  If it doesn't trip, the GFCI is bad.  If it still trips, the appliance is bad. It happens.

That's not how GFCIs work.
GFCI detectors are not connected to the ground wire at all.   (Mind you GFCI receptacles are connected to ground, but only for the sockets. A GFCI breaker doesn't even have access to ground.)
Further, UL requires that devices be built intending to have no electrical interaction with the ground wire at all. So the saw should not be interacting with ground. If the saw isn't, then there are only 2 possible current paths:  From hot via the machine's internals to neutral.... and from neutral via the machine's internals to hot.  And AC power switches between them 120 times a second.
Machines cannot store electrons.  (it would take something like the Large Hadron Collider, but even that couldn't store enough electrons to trip a GFCI.)
All electrons that come in must come out effectively instantaneously.   Therefore, current flows should be equal on hot and neutral on a single-phase circuit.
Since current flows should be equal, the GFCI should not trip.   It only trips when currents are imbalanced, meaning electricity is leaking via a third ??? path.   The GFCI doesn't care whether the ??? path is to ground, via a human or pet, etc.
In a motor device, especially one where the motor's current is interrupted, this third path can be between the motor windings and the (grounded) motor chassis, due to a defect in the motor windings.  A mega-ohm-meter can be used to test for this, after disassembling the machine to avoid putting its test voltage on parts which can't handle it.  This isn't your problem on a machine within warranty.
Very often the third (fault) path is via the ground wire.  Strictly as a diagnostic, you can try interrupting the ground path, by using a 3/2 prong &quot;cheater&quot; and insulate the little tang so it doesn't contact the receptacle cover plate.  If the device stops tripping GFCIs at that point, that confirms an internal ground fault.  Don't continue in service a broken appliance with a ground fault.  One day you'll use it on a receptacle that is not GFCI, and the appliance will just kill you instead.
Appliance makers who are putting out appliances to be used in garages and sheds, really need to learn to make them not trip GFCIs.  Code has required GFCI in those locations for quite some time.  Don't let them &quot;try to make this your fault&quot;, it's theirs.
But as a last sanity check, plug it into a different circuit protected by a different GFCI.  If it does, then yeah, it's the appliance.  If it doesn't, I'd examine the original GFCI.
