How to remove crankarm on ToSeven DM02? Seems stuck

[maxwolfie]

Is the square drive a standard system?

Do I need a special tool to remove the crankarm?

"Stuck" is how these old style cranks stay on. Do you not have a standard square taper crank puller? Use a cheater pipe on the handle if you need more torque.
