My timber does not feed through correctly when thicknessing.

The way remedy this problem is to clean the thicknesser bed thoroughly from any loose shavings, then apply white spirit to the bed with a clean rag. After this the bed should re-waxed or treated with silicon spray (part no. CWA195). Please note: do not use any oil based products on the thicknesser bed as this will transfer to the passing timber. If cleaning the thicknesser bed does not solve the problem, the cause could be either blunt or incorrectly set planer knives in the cutter block. Also make sure that a square datum face is being achieved on the planing function before thicknessing the timber.
