Table Saw Mod. RT-40
Instructions for replacing the Sawdust Guard
A
Your machine is equipped with a wooden guard (ballast) that helps to prevent sawdust from being blown up
through the table insert. This is a very important feature when dust collection is absent or very poor. Due to normal
wear it becomes necessary to change this guard, proceed as follows: Raise the saw blade to its maximum height,
remove the table insert. Replace the wooden guard with a new one of the same dimensions. Next, mount the new
piece of wood in the guard, and reassemble table insert. Turn the saw on and slowly lower it to its minimum height,
executing the cut in the wood. (Always lockout the power supply when doing blade maintenance)
