3. Adjusting cutterhead to panel surface
a) Check with straight edge to assure cutterhead is set higher than base plate before continuing.
b) To adjust the cutterhead setting, switch on the machine and set it on a piece of flat panel (panel
does not need to have wood edge attached).
Caution: Make sure panel is secured to table with clamps, screws, etc. If cutterhead setting is
incorrect, an unsecured panel could be thrown off the table possible causing an injury!
c) SLOWLY turn the front adjustment knob (4) to lower the rotating cutterhead onto the panel.
Turning the knob clockwise will raise the cutterhead off of the panel, turning it counterclockwise
will lower the cutterhead onto the panel. (A coin may be used to turn the inner portion of the
knob.)
The knob is equipped with a built-in spring to produce a ratchet action. Each “click” of the ratchet
raises or lowers the cutterhead approx. 1/10mm – 4/1000”.
d) When adjusted correctly, the blades will slightly touch the panel without leaving any marks.
4. Feed rate
The maximum feed rate depends on various factors including depth of cut (how much material is
removed), width of cut (how wide the edge is), condition of blades, material being planed, etc.
While the BH 556 can remove up to 1/8” of material in one pass, it is recommended that the wooden
edge be glued as precise as possible, generally about 1/16” higher than the panel.
A power plane can only produce a clean cut when it is operated at full RPM!
