1 week ago.. I would have mentioned to order the screws too.... Extras... As they snap easy....

Before you change them... Get some light weight spray oil and try to flush the bearings as sawdust gets in the seals and the head makes a thumping sound as you move it up and down. Catch all oil in a rag and later be careful of Spontaneous combustion of the oil rags.

Keep a tooth brush size wire brush to scrub the roller rails. Sawdust sticks to the rails.

Clean the rubber drive belt cogs.

Good Luck,
