The grub screws in the sprintjet 9 brass motor to impeller coupler have seized. The 1.5 mm Allen key is slipping. Any ideas on how to proceed. It’s only weeks old and the grub screws are incredibly tight. I used a new 1.5 hex drive.

Use a 1.5mm hex wrench to loosen the set screws on the motor shaft coupler. If the screws are seized, apply penetrating oil and allow it to soak before attempting to loosen them again.
