Feed  rollers  at  the  front  and  rear  of  the  cutterblock  push  and  pull  the  wood  through  the
rotating  cutter  knives.  The  infeed  roller  is  located  at  the  front  of  the  block  and  is  made  of
serrated steel. In order for it to operate effectively it must be kept free of resin. Clean off any
build up of resin using a stiff brush with a proprietary cleaner or solvent. The metal serrations
will be imprinted on the timber as it is forced under the cutterhead, and these marks are then
removed by the cutting of the planer knives. At the back of the cutterblock is a smooth metal
roller.  A flat belt powers both rollers through a gear-reduction mechanism, and each roller is
spring loaded to accommodate variations in wood thickness. These roller springs are adjustable
to  enable  you  to  vary  the  degree  of  pressure  that  they  exert.  For  further  details  see
‘Maintenance’.

For  thickness  planing  thin  stock  or  making  finish  cuts,  it  is  a  good  idea  to  make  an  auxiliary
table with a smooth plastic laminate top. The table can be a straight piece of plywood with a
cleat on each end. Wax the laminate surface often with a non-silicon wax.
