The drive chain for the feeding system on the thicknesser can very easily be lubricated by opening the
planer in feed table. Now the drive chain can be seen right next to the planer table locking bolt. The
little cover plate X0164 can be removed by removing the table locking bolt. When however the chain
has to be replaced, then the complete saw spindle table has to be taken off to reach this chain.
