HOW TO POP OFF RISERS
How to Change the Risers
Popping off the risers is simple to do. Usually, you can gently wiggle them out using only your hands. However, because this is a natural product and humidity does sometimes swell wood, you may need to use a bit more force.
Flip the board over and push on the riser pegs. This should do the trick.
If they are really stuck use a golf tee or the like and, with a hammer, gently tap the riser pegs until they become loose. You can then pull them off with your hand.
