Adjusting the Cutting Unit
Pitch
Cutting unit pitch is the difference in height of cut from
the front of the blade plane to the back of the blade
plane. Use a blade pitch of 6 mm (1/4 inch), meaning
that the back of the blade plane is 6 mm (1/4 inch)
higher than the front.

Position the machine on a level surface on the
shop floor.

the front tip of the blade. Rotate the blade tip to
the rear and measure from the floor to the tip
of the blade.
5.
Subtract the front dimension from the rear
dimension to calculate the blade pitch.
6.
