time or try using kiln dried materials.
However if moisture is not the issue then
check the knives to ensure that they are
sharp and not dull.
Chipped Grain: This is typically occurs with
materials containing impurities or when
cutting against the grain. Chipped grain
may also be caused by dull or damaged
knives (chipped blades).
Remedy: To prevent issues such as
chipped grain try removing less material per
pass by adjusting the cutterhead height. If
material doesn’t have a heavy
concentration of cross grain you may want
to check and inspect the cutterhead knives.
Chip Marks and Indentations: This is
typically caused by too much material being
removed making for larger wood chips that
are unable to be cleared through dust
collection port. Because of the debris
staying in the machine it gets re-deposited
on to the workpiece and firmly pressed into
it by the outfeed rollers resulting in
indentation or marking. This again may also
be caused by knives that are too dull or
damaged and cutting poorly.
Remedy: To help eliminate this issue
ensure that the cutterhead knives are sharp
and not dull or damaged. Also try removing
less material at a time by reducing the
depth of cut and only using wood suitable
for planing with moisture content less than
20%.
CHANGIG DEPTH OF CUT
The depth of cut when planing is adjusted
by the cutterhead adjustment crank located
on top of the jointer. To raise the height of
the cutterhead turn the crank clockwise and
to lower it counterclockwise.
The cutterhead height adjustment crank is a
simple yet accurate way for obtaining
consistent cut depths on multiple passes.
The height adjustments lead screw has a
screw pitch of 16 threads per inch. This
means that every full rotation of the height
adjustment crank will move the cutterhead
1/16” up or down and every quarter turn
would move the cutterhead 1/64”.
Anytime you switch from raising the
cutterhead to lowering the cutterhead you
may experience slight amount of backlash.
Backlash occurs during the first turn of the
height adjustment crank in the opposite
direction from which you were previously
working so the first rotation of the crank will
not be exactly 1/16” of movement up or
down for the cutterhead. Backlash will not
be experienced when moving the
cutterhead in the same direction as you are
currently working.
NOTE
Maximum depth of cut may vary dependent
on the type of wood, hardness, and width of
material being planed. For best results we
recommend you remove no more than 1/32”
at a time for cleaner cuts and less stress on
the machine.
