Stock Inspection
Stock Inspection &
Requirements
Follow these rules when choosing and jointing
stock:
DO NOT joint or surface plane stock that
•
contains large or loose knots. Injury to the
operator or damage to the workpiece can
occur if a knot becomes dislodged during the
cutting operation.
DO NOT joint or surface plane against the
•
grain direction. Cutting against the grain
increases the likelihood of kickback, as well
as tear-out on the workpiece.
Jointing and surface planing with the
•
grain produces a better finish and is safer
for the operator. Cutting with the grain is
described as feeding the stock on the jointer so
the grain points down and toward you as viewed
on the edge of the stock (see Figure below).
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.

INCORRECT
Figure 23. Proper grain alignment with the
cutterhead.
Only process natural wood fiber through
•
your jointer. Your jointer is designed to
cut only natural wood stock. This machine
is NOT designed to cut metal, glass, stone,
tile, products with lead-based paint, or prod-
ucts that contain asbestos—cutting these
materials with a jointer may lead to injury.

•
Scrape all glue off the workpiece before
jointing. Glue deposits on the workpiece,
hard or soft, will gum up the cutterhead and
produce poor results.
Remove foreign objects from the work-
•
piece. Make sure that any stock you pro-
cess with the jointer is clean and free of dirt,
nails, staples, tiny rocks or any other foreign
objects that could damage the cutterhead.
These particles could also cause a spark as
they strike the cutterhead and create a fire
hazard.
IMPORTANT: Wood stacked on a concrete
or dirt surface can have small pieces of con-
crete or stone pressed into the surface.
Make sure all stock is sufficiently dried
•
before jointing. Wood with a moisture con-
tent over 20% will cause unnecessary wear
on the cutters and poor cutting results. Excess
14" Min.
moisture can also hasten rust and corrosion.
